Dear Friends,

I am getting a MOVE_CAST_ERROR dump, (Class:CL_SWL_BWSP_BADI_SERVICES=====CP Method:EXECUTE_WF_BWP_OBJ_ATTRIBUTE, Line 11 LH_EXIT ?= M_EXIT.."), when I try to execute Business Workplace and click on INBOX ----> Workflow then it gives me dump..

Please suggest the solution?

Thanks and Regards
