I tried running task using workflow process manager through srvrmgr.
run task for comp WfProcMgr server SBLD02AP01 with ProcessName="cwaAlertMasterWorkflow"
SBL-ADM-60070: Error reported on server 'SBLD02AP01' follows:
SBL-SVR-01042: Internal: Communication protocol error while instantiating new task SBL-OMS-00203: Error 6750391 invoking method "RunProcess" for Business Service "Workflow Process Manager"
SBL-OMS-00203: Error 6750391 invoking method "RunProcess" for Business Service "Workflow Process Manager"
SBL-OMS-00107: Object manager error: ( Error updating business component at sep '<?>'.(SBL-BPR-00187) (0x6700bb))
SBL-OMS-00203: Error (null) invoking method "(null)" for Business Service "(null)"
This custom workflow is just a simple workflow that works on Business Process->simulator and Siebel Tools simulator.
1) I had activate the workflow.
2) The SRF using is the latest version.
3) From the workflow instance monitor I couldn't see any log and believe that the error occur before the custom workflow is called.
