Dear Shahzaib,

The workflow engine not able to find the User defined for approval. Make sure that the workflow assignment in the configuration template is valid.

Thanks Kumar for your kind response !

I had verified user assignment on workflow and there is no issue with it [ Approver user exists in system].

Actually the problem was with Workflow version i.e. Activated Purchase Order Workflow Version was not same as of which respective PO is running on.

So what I did, I re-call all stopped PO and submit again and it works !!
