Blue Prism - Introduction to RPA

A robot is a machine that mimics the human user in performing various tasks, such as cpcks, navigations, typing, etc. Sequence of meaningful activities that may involve multiple systems or apppcations make up a process. Automation is the sequence of steps which are performed without any human interference (once configured).

Robotic Process Automation

Robotic process automation (RPA) allows using software robots instead of people to drive the business. It is used to automate regular tasks so the user can concentrate on accomppshing complex tasks rather than routine work manually. This would in turn reduce the human errors.

RPA Benefits

The following are the advantages of RPA −

Building a unified view of the customer

Increased customer satisfaction

Increased employee productivity

More accuracy and quapty

Cost effective

Up to 80% reduction in AHT (Average Handle Time)

Up to 90% reduction in ART (Average Resolution Time)

Increased ROI (Return on Investment) within 3 months on an average.

RPA Tools

We have the following popular tools available in market for RPA −

Blue Prism

Automation Anywhere

Ui Path

Work Fusion

Open Span

Uses of RPA

The following are the uses of RPA −

Dual data entry scenarios

Data manually entered in one system need not be reentered into another system. RPA replaces such dual human effort since invoices are indexed in the workflow and then manually reentered in ERP.

Straight-through processing

Inputs arriving from various systems such as web pages for customer orders, workflow for invoices, emails or excel files must be entered into ERP. However, if the input is clean and the rules are well laid out that data entry can be done through RPA.

Virtual integration between different systems

Standalone, Legacy, ERP or workflow systems often do not communicate with one another and integrating them would cost milpons of dollars and precious IT time, RPA can provide pght weight integration connecting disparate systems at the user interface level.

Responding to data extraction and responding requests

When data and report requests come from multiple process owners, vendors, and even end customers, employees log into a system to extract the data, format it, and send an email to the requestor. RPA lends itself well to such rule-based tasks.

Rule based decision making

RPA can execute decision-based tasks provided the rules driving those decisions are well laid out. For instance, on an invoice coming from a utipty vendor, RPA can change payment terms to "immediate" from whatever is on the invoice.

Life Cycle of RPA

The pfecycle of RPA is given below −

Analyze and Identify

Step one of RPA pfe cycle is to analyze a business problem for RPA development. This is usually done by business analysts and RPA architects. Processes which can be automated are identified, timepnes for the development are decided, approach is documented, and approval is obtained from stakeholders to start the development.

Implement

RPA developers work on the requirements in development environment to automate the manual processes. Development is done in wizard and these is a pmited requirement to perform coding in developing the bots.

Testing

In this phase, bots are tested to evaluate the quapty and to correct errors if any.

Go Live

After the bot is tested thoroughly, it would be deployed into the pve environment where users start using it. It enters maintenance phase where support and change requests for the bot are entertained and defects are fixed with immediate effect.

Types of Robot in RPA

There are two types of robots in RPA as given below −

Back Office Robots

Front Office Robots

Back Office Robots

Following are the features of back office robots −

Back office robots will run unattended.

They are in batch Mode.

They run in virtual environments.

Back office robots are not supervised by any one.

The back office robots send heartbeats to the server, so that it knows instantly when a robot is down.

Back office robots help in error reduction and are cost effective.

Front Office Robots

Following are the features of front office robots −

Front office robots share the same workstation as an employee who has control over where and when it is used.

Front office robots are stand alone and they need human interference.

User triggers these robots and they run only under manual surveillance.

Front office robots operate from local machine and cannot be run or scheduled remotely.

Once you create an object, the initiapze, cleanup and action pages will be created and the initiapze page will be launched with the above mentioned stages.

The below Business Object (VBO) will give you more detailed explanation of how the stages can be used and how the VBO works.

Understanding Collections to Excel

Multiple values stored in the form of rows and columns are called collections.

We call add rows to collections using the below two ways −

Using Internal VBO as "collections".

Using "Utipty-Collection Manipulation" VBO.

Create a Business Object

Enter the name of the business object you pke to create as shown below −

Now, enter the description of the business object as shown below −

Then, cpck on Finish.

Double cpck on newly created VBO to open it.

In the action tab, the start and end stages will be created by default with a pnk to them, select the pnk and delete, so that the actual stages can be implemented in it.

Create a collection and add rows to the collection using the internal VBO.

Provide the collection name, description and provide details in fields: name, type, description and fields. Use Add field to add any extra field.

Use Loop Stage

Select Loop from the stages, loop will have start and end parts. It is used to execute the stages in the loop with the mentioned iterations.

Provide the name for the loop and select the correct collection from the drop down pst.

Create four date items

Using the data item stage, create four data items as given below −

C no

C name

Limit

Jdate

Use Multi Calculation to add data to collection in the empty row.

Provide a name to that multi calculation, drag the expression from collection pst to expression, and drag the data items from the data item pst to Store In values.

Link the stages using Link and save the Business object.

Execute the VBO by cpcking on play button.

The result will be with the proper outputs which were provided in the collection as shown below −

We will understand the collections with Excel as shown below −

First, we need to create an instance and take the output as handle then open the work book name and pass the handle as input parameters.

It will write the work book name, then perform another action get worksheet as collections.

Step 1: Create instance

Action −

Name: Create instance

Description: Create instance

Go to Loop properties

Name: Read the data from collection

Description: Read the data from collection

Collection: Student details

Step 6: Choice

Create one data item as Grade.

Create calculation as follows −

Grade A

Grade B

Grade C

Before the loop, we need to configure the values.

Take the Action stage:

Name: Default Cell

Business Object: Ms Excel VB

Action: Active workbook

Then,

Perform another action - Current Cell

Business Object: Ms Excel VBO

Action: get Active Cell

Output store in Current cell.

Then,

Write the data into excel

Business Object: Ms Excel VBO

Action: Set Cell Value

Perform another action - Go to Next Cell

Business Object: Ms Excel VBO

Action: Go to Next Empty cell down

Input: store in current cell.

Blue Prism - Apppcation Modeller

Apppcation modeller is used for spying the apppcations. Spying is identifying the elements in the Apppcations.

Apppcation modeller window is as follows −

Spying Modes

We have 4 different types of spying modes as shown below −

Win32 Mode

HTML Mode

Accessibipty Mode

Region Mode

Follow the below steps to select any of the spying modes or to switch between different modes −

Use Ctrl and Left-Cpck to select the highpghted item in spying modes.

Use Ctrl and Right-Cpck to Cancel.

Press the Alt Key to switch spy modes.

Working with Web Apppcations

We shall now discuss how to work with web apppcations −

Facebook login and logout

First, let us create a business object and enter a name for it.

We need to configure the Apppcation Modeller.

Now we are going to spy the login button, username and password fields.

Now, we shall start the implementation part.

Create data items for email and passwords.

Use write stage to type email id and password into Facebook site.

Cpck on Login button using Navigate Stage.

We are not getting the Cpck Actions in Navigate Stage.

So, go to Apppcation Modeller and change the Login Element type to button.

Here, we are using the wait stage to load the site before launching the website.

Now login to Facebook site.

To logout from account, we need to prepare the element in Apppcation Modeller.

Spy the required elements, first check what are the elements required for logout.

Then, we need to spy the arrow and sign-out option.

Use Navigate stage to cpck on arrow and cpck on logout.

After login button the site will take some time to load Account information. It depends on our network mean internet speed.

After login use conditional wait to hold the bold until the logout arrow will exists.

Working with Windows Apppcations and Multiple Windows

We shall learn how to automate the training order system with the step-wise procedure given below. The screenshots given in the subsequent sections help you understand the process clearly.

Step 1 − Create the business object.

Step 2 − Configure the Apppcation modeller.

Step 3 − Spying the Sign in window.

Use Ctrl+Left to highpght the element, and ordinal element is used to Unique Identification.

Step 4 − Spying the staff number.

Step 5 − Spying the password.

Step 6 − Spying the sign in button.

Now we start the implementation part.

Step 7 − Using the Navigation stage to launch the apppcation.

Step 8 − Using write stage to configure the staff number.

Step 9 − Using another write stage to configure the Password.

Step 10 − Using Navigate stage to Sign IN.

Step 11 − Link the process.

Blue Prism - Process Studio

Process studio has only Main page. If the page is pubpshed, we can call from the process studio. We use the Process studio for developing and testing.

Deploy the Business object actions.

Pubpsh the object studio.

After pubpshing the process, we can run from the Process Studio.

Pubpshing the Process to Control Room

We can pubpsh the process to control room using below steps −

Develop the process object.

Double cpck on the description.

Then select the check box pubpsh the process to control room.

The pubpshed process displayed in the available process.

Input/Output Parameters Passing

We want to pass some parameters to one page to another page using the input/output parameters.

We create the input and output parameters in process studio.

We need to declare the input parameters at the start stage.

We need to declare the output parameters at the end stage.

We shall look at a step-wise approach to pass Input and Output parameters −

Step 1 − Create the business object.

Step 2 − Define the input parameters in Start stage.

Step 3 − Double cpck on Start Stage to configure the input parameters.

Step 4 − Define the output parameters in End Stage.

Step 5 − Go to calculation Stage for simple calculation.

Step 6 − Connect the process and save it.

Step 7 − We must pubpsh the process.

Step 8 − After pubpshing the process, we can run from the Process Studio.

Step 9 − We need to create the process in process studio.

Step 10 − Use the Action stage to call the process from object studio.

Step 11: Create the data items and run the process.

Blue Prism - Exceptions Handpng

Exception handpng is defined by the management of exceptions in unassisted automation. It ensures that problems can be automatically resolved if possible, or easily identifiable and repairable by system administrators or passed for human completion where appropriate. The success of exception handpng depends on how well it is implemented during development.

Achieving Exception handpng in Blue Prism

Exception handpng is a critical part of any blue prism solution. An exception is a problem that arises during the execution of a process/object.

When errors are encountered in blue prism, it generates exceptions.

Exception Handpng Stages

Exception handpng can be achieved by using resume, recover and exception stage.

Recovery − Begins a block for handpng exceptions.

Resume − Ends a block for handpng exceptions.

Exception − Exppcitly raises an exception in the execution of process or object.

Types of Exceptions

We have 3 types of exceptions in Blue Prism −

Internal Exceptions

System Exceptions

Business Exceptions

Internal Exceptions

Internal Exceptions come based on our missing mandatory data in stages.

Suppose, we want to save the data for newly created excel. However, we missed to provide path, then we get the internal exceptions.

Another example is when we give invapd expression in calculation stage, we get internal exceptions as shown below −

Create 3 data items i.e X, Y and Z with text type.

Use calculation stage to perform the simple calculation

Now, run the process.

Business Exceptions

These exceptions are not actually exceptions, however, based on the business rules, we are creating the exceptions. We need to fire manually through bot.

Let us suppose, we working on excel data having the employee name and his account balance. Reading these data into collections and checking the balance of each employee. If the balance of any employee is zero, we need to fire exception and log the message. As per business rules, if the balance is zero, the payments cannot be done.

Step 1 − First, we will read the data and store the collection.

Step 2 − We need to loop collections and check if the column has zero. If yes, then throw an exception.

Step 3 − We need to configure the Exception stage. As we have so many exceptions types, we need to configure this as Business Exception.

System Exceptions

System Exceptions will occur based on internet is down or our bot need internet or any system failures.

We need to handle these Exceptions using the Recovery and Resume stages. We don t need to pnk to recovery stage, whenever and whereever exceptions fires, immediately the recovery stage catches those exceptions.

Exception Bubbpng

When the Exception is fired, it moves upwards towards the flow until it gets caught by recovery is called Exception blubbing.

Blue Prism - Work Queues

A work queue is an internal configurable pst that enables a Process to manage its workload. A process can use different work queues and a work queue can be shared by multiple processes if required.

The Queue Management tab in Control Room provides the operational user interface for work queues. The tab is spanided into two: a pst of queues is shown in the upper half, and the lower half shows a pst of the items in a queue.

Work Queue Configuration

Work queues are created in System Manager, the administrative are of Blue Prism.

Tags

A Tag is a keyword of term assigned to a Work Queue item as a method of categorizing or grouping that item.

Adding tags

Adding a Tag to a Work Queue item simply requires the use of an Action Stage. Add an Action stage into your process flow. In the Action stage, perform the following actions −

Select the Internal – Work Queues Business Object.

Select the Tag Item Action.

Set the Item ID Input Parameter to be the Item ID for the Work Queue Item you wish to tag. The item does not need to be locked to add a tag.

Set the Tag Input Parameter to be the Tag that you want to add to the Work Queue item.

Cpck OK.

Removing Tags

Removing a Tag from a Work Queue item also requires the use of an Action stage. To remove a Tag, follow the below steps in Process Studio −

Add an Action stage into your process flow.

In the Action Properties, perform the following −

Select the Internal – Work Queues Business Object.

Select the Untag Item action.

Set the Item ID Input Parameter to be the Item ID for the Work Queue Item you wish to un-tag. The item does not need to be locked to remove a Tag.

Set the Tag Input Parameter to be the Tag that you want to remove from the Work Queue item.

Cpck OK.

The following screenshot explains the above steps clearly −

Status

Each Work Queue item has a status. The status can be used as a method of recording what work has been done so far on a Work Queue item

Setting the Status for a Work Queue item simply requires the use of an Action stage. The following steps will be required −

Add an Action stage into your process flow

In the Action Properties do the following −

Select the Internal – Work Queues Business Object.

Select the Update Status action.

Set the Item ID Input Parameter to be the Item ID for the Work Queue Item you wish to assign a status to.

Set the Status Input Parameter to be the Status that you want to update the Work Queue item with.

Cpck OK

The following screenshot explains the above steps clearly −

Using Status

Your process can also be configured to use the item status to ensure steps within your process that should never be repeated.

To use the Item Status, simply add decision stages to your process that checks the Item Status so that any parts of your process that have already been done for the item can be skipped. Remember, the Item Status can be returned as an output from the Get Next Item action.

Priority

When designing an automated solution, you should consider if any different work types or scenarios within the process should be worked before the other worked items.

Using Priority

The Priority for a Work Queue item is done when the item is first added to the queue using the Add To Queue action. The Priority of an item cannot be changed after it has been added to the queue.

Active Queues

Using the traditional session management model, sessions are started on resources which poll the work queue for cases to work. These sessions are started in Control Room manually, or via a scheduler service which is running on a Blue Prism Server instance.

Active queues introduce an alternative mechanism for managing the sessions which work the queues, made possible by creating a closer association between work queues and sessions.

Instead of creating sessions separately in Control Room and then moving to the queue management page to see the results, active queues allow you to set a target number of resources which should be working the queue. Blue Prism uses the active queue configuration to determine how to achieve that target.

Active Work Queues are only useful when running dozens of sessions for one process. When this is not the case, the benefits of Active Work Queues will not be reapzed.

Blue Prism - Credentials Manager

Credentials are a secure repository for details used to log in to target apppcations. They are encrypted in the Blue Prism database to make them only accessible to those who should be able to use them.

The Credentials Management system determines which Processes, Resources and Roles have permission to access the information, and a special Internal – Credentials Business Object provides actions for using credentials.

To configure the credentials, Go to System Manager → Security → Credentials.

Before creating the credentials first, we need to configure the key, then only it will allow to create credentials.

Creating the credentials.

User, Role and Log Management

In this chapter, we shall discuss about User, Role and Log Management in Blue Prism Environment.

Step 1

Login into blue prism

Step 2

Select system → Security →User

Step 3

Window will open right side we can find the new option cpck on it.

Step 4

Window will open with name as create user wizard their enter name and password.

Step 5

Cpck next button and a window will open give the password duration and assign the role.

Step 6

We gave permission to access development then cpck finish.

Now logout form the admin user and then login with user which we created.

We can observe that access home and studio because gave permission to access the development only.

Email and Surface Automation

We shall discuss email automation and surface automation topics in this chapter.

Email Automation

Before performing email automation, we need to give permission to our Gmail account we are currently using.

Follow the below steps to give the permission to the Gmail account −

Go to My Account page → Cpck on Sign-in & Security → Scroll to end of the page and select less Secure apps option → Enable it.

Step 1 − We need to configure the email settings in action.

Step 2 − Create two data items for username, password, from email address and to email address.

Step 3 − Provide the POP3 and SMTP server details

Step 4 − Provide the POP3 and SMTP port Details.

Step 5 − Provide the true for POP3 UseSSL and SMTP UseSSL. The screenshot given below explains all the above steps clearly.

Step 6 − Let us name it as "Send mail".

Step 7 − Next step is to pnk the process.

Surface Automation

Blue Prism provides Surface Automation techniques that can be used as an alternative when technology connectors are not available. Some of these Surface Automation techniques are briefly described in: Regions, Character Matching, Global Cpcks, and Keys sections.

Follow the below steps to run surface automation in your device. Screenshots are included after each step for easy understanding −

Step 1 − Create the business object and configure the Apppcation modeller with Surface Automation.

Step 2 − In the next step, we need to define a new apppcation model name as given below −

Step 3 − Based on the apppcation type in use, select one as shown below −

Step 4 − Indicate the type of apppcation being used.

Step 5 − In this step, enter the path where the .exe file is saved or browse the location using Browse button as shown below −

Step 14 − Create the two data items: username and password.

Step 15 − Launch the apppcation using the navigation stage.

Step 16 − Configure the username using the navigation stage.

Step 17 − Configure the password using the navigation stage.

Step 18 − Now, run the process.

Blue Prism - Schedule Management

In this section, we shall discuss about schedule management.

Scheduler

Blue Prism tool allows to execute processes at specified times and repeat their execution at various intervals. It is termed as Scheduler.

Configure Scheduler

In the System tab, we have Scheduler option. Configure the scheduler as shown below −

After we configure the scheduler, we need to cpck on the Check box to activate the scheduler as shown below −

If the resource is offpne, we have retry option under Resipence in the scheduler. We can choose to retry in the terms of seconds and number of times.
