Find all the recipients after workitem executed

Hello All,

     I have a workitem number say 711461 which is residing in the inbox of three people A, B and C. Now, before the execution of the workitem 711461, I can have the recipient list using FM SAP_WAPI_WORKITEM_RECIPIENTS.

Now, my problem is I want to have the same recipient list (A, B and C) after the execution of workitem. FM SAP_WAPI_WORKITEM_RECIPIENTS does not give this list once the workitem is executed.

Please guide me how can I achieve this?

Thanks,

Viraj.
