Asynchronous Method For Object ZVACASSIGN

Hi,

I am currently working on workflow solution for application processes in which applicants should be examined that way if an applicant is to be invited or to be rejected transactions should be triggered. I have created asynchronous method with events (rejected/tobeinvited) which should change status of workitem to be completed.

Unfortunately it does not work and workitem is still in process. Please advise on how status of workitem could be changed to "completed"; any input is appreciated.

Thanks in advance,

Alex
