Background task is not being executed

Hi all,

It's been some time since I've played with workflows and I have forgotten quite a lot, so I assume that this is a simple matter and I'm just forgetting something.

Background: In response to changes that are being made to one of objects in system I'm trying to an update z-tables. I've decided to use workflow events that are being fired during creation of change document.

What I did:

- I've created ABAP class that implements IF_WORKFLOW interface and implemented all Methods (especially BI_PERSISTENT~FIND_BY_LPOR and BI_PERSISTENT~LPOR, rest have only EXIT inside), added Contructor, event and my own method that do all work.

- I've prepared Workflow that was started with event that I've declared in my class and added one activity that is calling method (that do all work)

- I made all customizing that was necessary for this to run (like in transaction SWEC). Since this is SAP object and change object already exists, I did no changes in SWED

- for first test I've set it task work in dialog and added me as an agent

Result:

I'm changing an object. In effect in SWIA workflow is getting status STARTED and automatically a dialog step is added with status READY. I can execute it in business workplace. Dialog step is being set to COMPLETED, but workflow has still status STARTED - I've to click button "manualy end" in SWIA to make it change into COMPLETED. What could be the reason?

Next:

I've deleted agent for my task and I've set it to "background task"

Result:

I'm changing an object. In effect in SWIA workflow is getting status READY. No background task is being created automatically, why? When I click "execute workitem" and refresh then workflow status is STARTED and background task is being created, however It's not being executed, again why? When I go in details of this task then I can see that its start date/time and creation date/time are equal, so it should be executed right after creation.

Any ideas are welcome

Best Regards
