SAP Note 22787 - MD04: Branching to scheduled quantity in SD

Symptom:

If in MD04 you branch to a scheduling agreement item of sales and distribution via 'Environment -> Display element', the system always displays the first entered or selected item.

Cause and prerequisites

Incorrect entries in table T457C.

Solution
The additional data in the following lines must be changed:
1) MD01, VE, A, VA33; Additional data; old entry: VL, MDPS-DELPS; new entry: LPN, MDPS-DELNR; additional entry: VPO, MDPS-DELPS
2) MD01, VE, V, VA32; Additional data; old entry: VL, MDPS-DELPS; new entry: LPN, MDPS-DELNR; additional entry: VPO, MDPS-DELPS

The scheduling agreement number is transferred correctly with the new entry and the corresponding item is selected by the additional entry.
