You're right, CLOI_ORD_RESBU_IMP is the right table.
I tried to change CLOI_ORD_OPRU_IMP table and it worked well!
But if i try to change the components, the Value can't be saved in database:
So in this case, theres an empty database insert.
If i want to correct the component, i got an error:
"Das System hat keine Materialnummer übergeben/no MATNR served by system"
Any idea?
