Dequeue Work Item

[Florin Wach]

Hi Sandy,

I have experienced a very similar problem and I worked around that by using the new ABAP-Objects for the workitem's container. But apparently that container get's rolled back whenever the work item was cancelled (and not fully processed).  By the way, I'm talking about a synchronous dialog step.

Instead of writing the value immediatly back to the container, you could use the EXPORT TO MEMORY statement to pass information back from the transaction to the calling business object method, picking it up there to pass it back via the method container (as plain exporting element).
Another possibility could be, to use a separate database table with the work*flows* WI_ID as the key field and you pass this to the transaction (as hidden parameter or so). The transaction then can put entries there, as you wish, and you create an extended WORKITEM object with a virtual attribut holding the information from the db table. In the workflow you can then use the instance of the workflow itself to access it.

Maybe this gives you some more ideas.

Best wishes,
Florin
