Need to get details of Position/User for a task

Hello Experts,

I am working on a report where I am displaying Position/User for workflow items. Sometimes when the users are not assigned to Position in the organization structure then S XXXXXXX is coming, however when the users are assigned, the ID is coming. When I refer tables SWWORGTASK to get Position/User for work item, I get the IDs but I want their descriptions also. I though I can refer HRP1000 for Position Details it didn t prove useful as the data type of OBJ_ID in SWWORGTASK and the field in HRP1000 are different.

Is there any function module that I can use to get descriptions of positions/users for a workitem ID in one go?

Thanks and Regards,
