Application-Specific Customizing (MM-PUR-GF)
In Customizing for Purchasing, you define:
You enter a user name directly.
You enter a job or a position, for example. At runtime, the system then determines the processing staff member responsible.
Take care to ensure that this assignment is compatible with the processor assignment in Task-Specific Customizing for SAP Business Workflow. If, you enter a user, for example, the latter must also be the holder of a position in Task-Specific Customizing. If you enter a position, precisely this position must also be defined in Task-Specific Customizing and have users assigned to it.

You can implement an enhancement (user exit M06E0005) for a release code if you wish to have a different role resolution than the one defined in the standard system.
You make these settings via the Customizing activity (Purchasing
® Purchase Requisition ® Release Procedure ® ) Procedure with Classification. For more detailed information, refer to the Implementation Guide (IMG).
