Journal Approval: Invalid Application Role Error

Summary:

Hi Everyone, We are facing error in approval rule.

The task is assigned to an invalid application role null_Entity_Financial_Manager_AG in application context fscm.

Content (required):

We are trying to route the approval to 'Application Role' in THEN condition.

in THEN condition, application role = Journal Line.Account Segment1+"_Entity_Financial_Manager_AG".

This condition works in DEV1 instance but not in latest DEV7 instance. E.g. It routes correctly in DEV by generating aplication role string as "550_Entity_Financial_Manager_AG" but same is not happening in DEV7.

Is there anything we are missing out some process?
