Pega Flows

 How to configure flows in Pega .

first we have to Learn 

What is Flow rule?

• A flow rule is business process using shapes and connectors that helps in achieving the events,every work item cross in there life cycle.
• How do we Configure a flow rule?

• Flow rule is of Process Category.

Create a flowRule.

You can Specify the  additional configuration options:

Here we have two types of Flows.

1.Process Flow

2.Screen Flow

What is Process Flow?

• This is can be a simple flow to support the business process.Here users are able to route the taskes to other users,workList , work Basket and all other functionalities.

What is Screen Flow?

• The screen flow typically contains multiple assignment shapes that present information to the user, along with other shapes. 
• For example: Imagine you are filling an application form which contain N number of  fields,you can represents this fields in series of screens(pages) for effective user experience.

*Interview Question

1.What are the Differnce between Process Flow and Screen Flow?

Process Flow:

Process flow is the main flow for which you can create a case route to respective operators WL or WB, this can be persisted to DB,anything can be performed here. 

For ex: use integrator shape to call Websevices, call any smart shapes or what all shapes available can be used in this process flow.

Screen Flow:

• The ability to jump ahead or go back to different entry points in the flow at run time. 
• Routing options that are configured in the Start shape instead of in individual assignments.
• Because one user processes all assignments in a screen flow, you cannot route assignments to different users or to a work queue.
• User actions that are configured in the Assignment shape instead of in a connector.
• A single harness that defines the presentation, such as tabs or nodes in a tree, for every step in the screen flow.
• The ability to branch or call only screen flows that use the same harness.

Note:

When considering a screen flow in your application, keep in mind that not all shapes are supported and that a screen flow cannot be designated as a starter flow. 

Let start with Configuration. In this post , i am going to explain only congfiguration.

There are 4 main tabs:

1.Diagram tab.

2.Design tab.

3.Process tab.

1.Diagram tab.

Here we can see two main things  one is Draft and + icon.  let me explain.

• Draft button is provided to  On/Off  the Functionality. if draft is ON ,then you  can test  flow by adding shapes alone.
• + Icon is used to add shapes with in the flow rule,  there are many shapes are avialble in Flow Rule.

2.Design tab.

Flow-wide local action:

• This action acn be used throughout the case Lifecycle.
• Here we can add multiple Local actions. 

3.Process tab.

Start Settings:

1.Process Commander Internal flow: You can open the property and check ".pySystemFlow"

properety contians the data for this check box.

2.Create a new Work Object: On clicking this check box, the flow will create a new work item.

Case Creation Settings:

Temporary object: On selecting this check box, work item is created but with no ID.This work item will not saved in Database.

*  For Harness topic i will post separately.

Interview Questions:

1.what is Parallel Processing?

2.What are the Differnce between Process Flow and Screen Flow?

3.Diffence Between Split join, Split for each, SpinOff?

4.Diffence between Local action and Flow action?
