Creating a Loop

Build a complex activity in your business process.

Select the complex activity to see its properties.

Properties display in the Properties section of the Business Process Logic Page.

Select the Iteration Settings tab.

Select This Activity Runs Iteratively to create a loop.

Create a counter variable.

Define the counter variable:

In Properties, click the ellipsis in the Counter Variable field.
The Variable Reference Dialog opens.
Select the variable that you want to use and click OK.
If the Counter variable is set, the loop automatically increments the counter variable by one at the bottom of each loop. To increment by a different amount or to decrement, set the Counter increment. The Counter initial value allows the Counter variable to initialize before loop execution.
Define the Counter initial variable and the Counter increment variables:

In Properties, click the ellipsis in either the Counter Initial or Counter increment field, whichever you are populating.
The Variable Reference dialog opens.
Choose one of:

Option	Action
Variable	Select the variable that you want to use and click OK.
Literal	Enter the value in the Literal field and click OK.

Define a single rule for the loop.

You must define a rule for loop evaluation. The loop executes as long as the rule evaluates to true. Usually, a counter variable is used in the rule for the loop; however, this is not required. Any rule that evaluates to either true or to false is supported.

Complete the flow of the business process logic inside the loop:

Maximize the complex activity.
Add the activities from the Tool Palette that complete the logic.
Connect the activities to determine the flow of execution.
Minimize the complex activity.

The center of the activity icon is decorated to reflect the loop.
