Hi Nahuru,
- Go to OMSR and search the MARC-LADGR by field name and change the Selection Group from 94 to your required Group.(Say 101)
- Then go to OMS9 and check 94 and 101.94 will have MARA-TRAGR and 101 will have MARC-LADGR.
- Then use the Display and Reqd Enty for your Field Reference.
As for as route determination is concern,as Summet said,kindly do the route determination and check
Regards
Logan
