wf-batch - agent not found

Hi Good day,

i have designed a workflow and in one of the methods of my Object Type is M_get_approver where i try to get the approver.

when i test the method i can able to see the Agent or Approver.

but when i Execute the workflow using SWDD i cannot get the approver instead it Passes WF-BATCH.

When in my Method if i change out the SY-UNAME and Hard code the User name ex : 999999 i get the Agent or Approver from the work flow.

can i please know how can i pass the USERID instead of hardcoding in the method?

thank you ,

J.
