How to know that workitems´ve been put back in inbox

["Schröder, Ute Marion"]

Hallo everybody,
 
I=B4m facing an annoying problem,
due to a customer created transaction,
I have to delete certain records from the database in 3 cases:
First: If Workflow is complete successfully (no problem there)
Second: If the decision to be maid is negative (works too)
Third: If the user stops his work on a workitem and puts it back into =
his
inbox via cancel
 
This is my problem.
Is there a way to create coding that is only executed when a workitem =
that
has been in process is cancelled
to be executed again later on?
 
Up to now I=B4ve been not very successful on this.
 
Has anyone experienced this problem before and give me a hint where to =
look?
 
Thanx a lot for all your help
 
Ute
