Maintenance of UNTIL Loops

Use

You use an UNTIL loop in a workflow definition if:

At execution time with one of two possible alternatives the workflow is to "jump back" to process sections of the workflow definition again.

The workflow system can make a decision based on the contents of the workflow container.

In the workflow definition an UNTIL loop is represented with the symbol .

Features

An UNTIL loop consists of a sequence of steps processed by the workflow system until a termination condition is recognized as true by the workflow system. In an UNTIL loop, the steps are processed at least once before the loop can be terminated.

Outcome of UNTIL Loops

The evaluation of a condition can return the values true or false.

You assign an event name for each of the two values. These names are used to label the two outcomes of the loop in the workflow definition.

In an UNTIL loop, the return jump always occurs when the condition evaluation returns the value false. The workflow execution is continued if the condition evaluation returns the value true.

Activities

To define the loop you must assign names for the step and enter the outcomes. Use the condition editor to enter the termination condition. For further information, refer to Condition Editor.

The system creates a loop containing an undefined step in the workflow definition. You must then define the loop content.
