Hello Jodie,
The program now is more restrictive than when I first set this up. Now you have to define the salesperson in AR, then change the default in OE to this new salesperson in Group setup, Order Entry template and probably also under the Maintenance tab & OE template. Then go back to AR and delete the new salesperson before it is used. It will still remain as the default but give the error message when trying to leave the Header screen in OE without changing to a valid salesperson.
Regards,
Rick McLeod
