Checkpoints for rolling back work items

Use the checkpoint system functions to roll back work item data field values and processing to a previous step.

Guidelines for checkpoint placement and usage
In a workflow definition, place checkpoint system functions in the following order: BeginCheckpoint, RollbackCheckpoint, and EndCheckpoint.
BeginCheckpoint system function
Use this instruction to save the current values of the work item's data fields. These values are retained until an EndCheckpoint or RollbackCheckpoint executes.
RollbackCheckpoint system function
Use this instruction to mark the point at which saved data values replace the current values in the data fields that are designated for rollback. RollbackCheckpoint configuration options determine both which data fields are to be rolled back and where work item processing resumes after the rollback.
EndCheckPoint system function
Use this instruction to discard the data values that were saved with BeginCheckpoint.
Wait behavior
When WaitForCondition runs, the workflow system checks the system for a work item that matches the specified criteria. If no existing work item meets the condition, the waiting work item is moved to the Delay system queue.
