Error Your receipt could not be created successfully because the receiving transaction manager is no

Getting error in Procurement (OAF)

Your receipt could not be created successfully
because the receiving transaction manager is not running. Please contact
your system administrator for further assistance.

I restarted receiving transaction manager, request to restart/activate completes successfully, however users are still unable to receive and get the error mentioned above.  I did see many other docs referring to same issue but none of the solution apply and could work. Please advise

Thanks,

Susan
