Generic Output Parameter StepID and ReferenceStepID

Some activities require an optional input ReferenceStepID that points to a previous execution step.

This is done by capturing the parameter StepID from the required step. This output parameter StepID is generated for each activity, and it points to a unique number identifying each workflow step.

In the following example, the activity CreateWorkItem needs a reference to the CompareRecord step. 

<Activity Name="CompareRecord">
   <Action>CompareRecord</Action>
   <Description lang="en">Compare with previous confirmed version and generate an output document</Description>
   <Parameter direction="in" name="InDocument" type="document" eval="variable">workDoc</Parameter>

   <Parameter direction="out" eval="variable" type="document" name="OutDocument">workDoc</Parameter>
