Use option 0 - Profile, on the RC/Migrator main menu, then option 6 - Utility Model Services to display the CA General Model Services screen.
Create a copy of the @DEFAULT model using the 'T' line command next to the entry for the @DEFAULT model.
Update the new version of the @DEFAULT model using the 'U' line command next to the entry with the new model's name. This displays the CA General Model Utilities screen. Locate the entry on the screen for the LOAD utility. Use the 'E' line command next to this entry to edit the Load utility model.
Locate the line "#IF(%SORTNUM,=,0)" and modify it to: "#IF(%SORTNUM,NE,0)". Press PF3 to save the changes.
