Hi Kiran Kumar,

Kiran Kumar Valluru

I have got a question. Im doing custom workflow for SAP SRM ROS process. I have a workflow class as you mentioned, workflow template design as you mentioned, now i do want to trigger this workflow from a standard sap class (once after Save – Business partner). So can we implement the same webdynpro workflow trigger code to the post exit of the sap standard class?

Appreciating your help!

Thanks,

Rani.

Furthermore, use discussions section to get quick responses from fellow members.
