We are using standard MDG M BRF+ workflow WS60800086 for material change process.On approval of the change material is getting activated after that we are calling synchronous method for sending mails and changing status to final check approved.But after activation the workflow step "Agent and Route finder" is going to error stating "Error in getting proper agent group; user/non-user mixed group found". On restart of workflow it is getting completed and sending mails as well. Checked BRF+ tables and they are fine.
I got one sap note for this issue 2559196 but workflow event linkage and binding is fine when i checked.
so could some one help for this issue, so that workflow should work without restarting.
