Issue with TMSADM_WF user while setting up TMS WorkFlow

Hi Experts,

I am getting the error "Could not create user TMSADM_WF with exception 6" while setting up TMS Workflow on DEV(000).

We have removed it from CUA and tried but no luck, the last option i tried by creating the user TMSADM_WF manually and saved the settings of WF,

In this case RFC TMSWF@WORKFLOW_ENGINE generated automatically but autherization test is not working and could not able to modify this RFC to update the password of user TMSADM_WF which we have created manully.

Please help me to setup the TMS Work Flow. Screen shots attached for your reference.

Thanks in advance,

Regards,

Suresh Babu
