Hi,
OMBW field selection is only for old MBxx transactions - not for MIGO. For MIGO, the field selection is with OMJJ - Field selection (Enjoy), where there is no option to make the field as display only. However, you can hide the field if you can remove / delete the field UMCHA from theEnjoy - field selection.

Clik here to view.
Now, system wont show the field "receiving batch" in MIGO for corresponding movement type. Test the scenario and revert back.
Regards,
AKPT
