What is VBA?

VBA stands for Visual Basic for Applications. It is a combination of the Microsoft’s event-driven programming language Visual Basic with Microsoft Office Applications such as Microsoft Excel.

VBA enables you to automate various activities in Excel like generating reports, preparing charts & graphs, doing calculations, etc. This automation activity is also often referred as Macro. This way it helps users to save their time spent behind running the repetitive steps.

Blue Prism Tutorial for Beginners

Blue Prism is a UK-based software development company in the field of Robotic Process Automation. The group supplies software robot which helps to automate clerical back office processes that work exactly like a human.

The Robotic Process Automation which is shortly known as (RPA) was invented by Blue Prism. This fact itself shows that the company is pioneers in RPA software development.

Blue Prism software enables business operations to be agile and cost effective by automating, manual, rule-based, repetitive back-office processes and improving accuracy by developing a “Digital Workforce.”. The Blue prism tool offers flow chart like designer with drag and drop feature to automate each step of the business processes.

In this tutorial, you will learn

Components of Blue Prism

Blue Prism is a set of libraries, tools, and runtime environments for RPA.

Every software robot has two main parts:

  1. Process Studio
  2. Object Studio

What is Object Studio?

Object studio is a where we can create the Visual Business Object. It is abbreviated as VBO. VBO are created to interact with other applications.

We will see that Object Studio looks very like Process Studio. There are key differences, which are:

  • Object Studio offers some “stage” which are not available in the Process Studio
  • Object Studio does not have a Main Page, but it does have two default pages
  • Pages are organized as a flat group instead of hierarchy like in the Process Studio

Benefits of Developing VBO:

  • Consistency and scalability
  • Lesser Bot creation time for subsequent processes
  • System changes only needed to be updated in one location instead of for each process. Bot maintaince becomes easy

What is Process studio?

Process studio looks similar to a traditional flowchart. It is an area where an actual process is created. Apart from features offered by Object studio, it allows business logic, control loops, variables, and object call to be sequenced, and tested in a visible business flow. Each Page in Process has its tab, and generally, the process defined in the Process Studio is pretty similar to a flowchart.

A process acts like a human user. It implements a software robot’s logic. It is almost similar to personal interaction with several applications to carry out a series of steps which can invoke actions to carry out same steps.

Process diagram:

  • Process diagrams are comprised of various stages connected together using links to form logical structures.
  • Stages are selected from the toolbar and placed on the diagram using the mouse.
  • They can be selected, moved, resized, formatted, cut, copied, pasted, and deleted, much as you might expect.
  • Stages also have various properties that can be accessed by double -clicking.
  • Links are created using the link tool by dragging the mouse from the center of one stage to the center of another.
  • Dragging without the link tool can be used to select more than one stage at a time.

How to Create a New Process

From the main Blue Prism window, select “Studio” from tabbed menu at the top of the screen.

Figure: Main screen Toolbar

Or select the Studio icon from the left-hand navigation menu.

  • Right- click the Processes heading under studio and then select “Create a Process” from the context menu.
  • Name the new Process “First Process”.
  • Enter a brief description of the Process.

  • The new process will appear beneath the Processes heading. Now double-click it to open it.
  • Along the left-hand side of the screen is the Stages toolbar. To put a stage on the page click and drag it into position. Try this by dragging a few different stages onto the page.
  • You will notice that one of the stages in the stages toolbar has a blue rectangle highlighting it. Whichever stage is highlighted will be the one added if you click directly on the page. Click on the calculation stage on the toolbar to highlight it.

Figure: Process Studio Stages Toolbar

Here, you can notice how the cursor changes and has the calculation stage icon next to it. Now click on the process page to add a calculation stage. This saves you having to return to the toolbar if you have several stages of the same type to add.

Even with the calculation stage cursor you can still drag and place other stage types.

When stages are on the page you can:

  • Double click on various stages to view their properties
  • Press the Save button but keep the diagram open.

Space in Process Studio is effectively infinite, and pan and zoom tools can be used to maneuver around the diagram. The grid lines and “snap” settings are on by default, but these can be switched off (via the View menu) if necessary.

Advantages of Process Studio

  • A process is very much similar to a business object.
  • Every process is defined by using one or more pages
  • Each page contains various stages and data
  • Always begins at its Main page
  • Each page in a process has an individual tab, which allows you to divide he processes into various logical groupings.
  • A process acts like a human user who thinks and types very fast.
  • Need to publish the process then only it visible to Control Room.
  • The biggest advantage of the process studio allows you to design the logic by assembling the design surface graphically.

What is Business Objects

To implement RPA system in any organization, a real process would be needed to do some useful tasks and to do so; it would need to work with external applications.

The interface to an application is never contained in the process diagram, but in a separate diagram which is called Business Object.

  • A Business Object is never configured in Process Studio but in a distinct, environment which is called Object Studio.
  • The main aim of Business Object is to provide an interface to single application.
  • A Business Object is not exposed to Control Room and is never used on its own. Instead, it is always used by a Process.

Blue Prism

Let’s get started.

1. Documentation

Begin with the end in mind.

In the context of RPA, this means you should start off by documenting the process that you will be automating.

We call this the Process Definition Document (PDD), and it minimally comprises of the process map, as well as a detailed step-by-step walkthrough of the process. These process steps are usually augmented by screenshots for clarity purposes, and may include pertinent information such as possible exceptions and error handling.

Other useful information to include inside the PDD are:

· Contacts of the process SMEs

· “As is” process metrics, e.g. transaction volumes, average handling time (AHT), etc

· In scope and out of scope

One hidden advantage of doing this is that the PDD can serve as part of your organization’s Business Continuity Plan (BCP). For example, if there is an outage in the production bots, your SMEs should be able to pick up the PDD and follow the instructions there to perform the process manually (as a last resort, of course).

2. Planning

If you fail to plan, you plan to fail.

The same goes for RPA development as well.

It is generally not advisable for one to jump straight into RPA development without first considering the high level design.

What this means is that you need to identify beforehand the various components that altogether make up your solution, and how these components interact with one another.

One great hack — create a generic and process agnostic framework that enables you to deal with any use cases in a consistent and structured manner.

3. Modularity

Implied from the previous point is the importance of modularity.

Modularity in this context means simply to break down a complex programme into bite-sized, more manageable components.

There are two important benefits of doing so.

Firstly, there are often common steps that occur across different processes, for example, logging into the SAP system. Rather than generating these steps from scratch every time you automate a new process, a smarter and more efficient way is to create a separate workflow that does so, and add this to your automation library.

So the next time you have a process that requires logging into SAP, you can simply invoke this workflow file as follows:

This greatly enhances the reusability of your content.

The second benefit is that modularity supports fine granular development and testing. This is especially useful when dealing with complex processes, as you can independently assign the development and testing of specific components to individual developers.

4. Readability

Ignoring the readability of your RPA script is a common mistake made by many new RPA developers.

Readability in this case means how easy is it for someone else (other than the developer) to take the script and understand what the software robot is being programmed to do. In fact, for complex processes involving hundreds or thousands of steps, the developer himself often lose track of what is going on if he does not take active steps to ensure readability.

Ensuring good readability will also drastically reduced the amount of time you spend during troubleshooting and debugging, as well as during bots maintenance.

To do so is fairly straightforward. Mostly, you need to make a conscientious effort to provide meaningful names for workflow files, activities, arguments and variables.

Moreover, as a best practice, all your variables and arguments should be aligned to a naming convention:

· Variables should be in camelCase, e.g. firstNamelastName

· Arguments should be in TitleCase, e.g. FileNameDefaultTimeOut

Also, all your workflow names should contain the verb describing what the workflow does, e.g. GetTransactionDataLoginToSAP.

Last but not least, you should make judicious use of comments and annotations to describe sections of your code which are not as intuitive. It is important to be selective though as you do not want to end up clustering your programme with redundant comments.

5. Avoid hard coding

Where possible, you should avoid hard coding all the external settings (e.g. file paths, URLs) within your script. By hard coding, we mean that the only way to change these settings is to amend them from within the script itself.

Hard coding should be avoid because these settings are prone to changes over time. For example, the file location where you download the daily report to might change due to business requirements.

The idea is to minimize unnecessary changes to the script, especially if it has already been deployed to production, to avoid introducing additional bugs or errors. Also, if these settings are used multiple times within the script, if you hard code, you need to know exactly where the changes are required (chances are that you do not).

The most efficient way to store these parameters is to use a configuration file, an example of which is given below:

In this example, we have created an Excel spreadsheet containing three worksheets where the external settings, constants and automation assets are stored.

6. You are not alone

No, I am not referring to the 1995 Michael Jackson classic.

Chances are that as a beginner, you are likely to encounter some seemingly “insurmountable” problems during your development stage.

Rather than tearing your hair cut trying to resolve your issues, keep calm and google it! For it is highly likely that someone else have encountered the same problem and found a solution for it.

You will be pleasantly surprised by how helpful Professor Google can be.
