RFC to update/ reject work flow

Question

Hi Experts,
Is there any RFC/ FM to approve or reject the work flow?
I am using SAP_WAPI_DECISION_COMPLETE, with following inputs:
WORKITEM_ID <000000665113>
LANGUAGE = EN
USER  = <user id>
DECISION_Key  = 0001
DO_COMMIT= X
It gives:
return code = 2
message line: M = E, line =     Work item 000000665113 is not a user decision
Message structure
MSGID                M            MSG        MSGV1
SWR                  E                 205           000000665113
Where am I going wrong? Need help.
It shows  ready status after execution at SWIA.
Is there an alternative?
Thanks,
Ritu

Hi Ritu
Call FM SAP_WAPI_GET_WORKITEM_DETAIL, the export parameter WORKITEM_DETAIL-TOP_WI_ID will give you the work item ID of the parent. If you do not have sub-workflows within the main WF, you will just need to call it once. But if you are using sub workflows and your step is inside the Sub-WF, then call it first to get the Sub WF ID, then Use the sub WF ID and call it again to get the MAIN WF Id ....
And if you want the details on the main Workflow, use the TOP_WI_ID and then call SAP_WAPI_GET_WORKITEM_DETAIL again to get the details of the main WF.

Good to see that you are learning ... however do keep the SCN Rules Of Engagement in mind ( http://scn.sap.com/docs/DOC-18590 ) . Ask only one question in one thread.
Also, your question are not very specific for SRM and hence the right place to post such questions are on the forum SAP Business Workflow http://scn.sap.com/community/bpm/business-workflow
Post your question on this (current) forum only when you need SRM specific advise for workflows.
