Hi,
I have implemented the value mapping for predefined data element distribution channel(VTWEG).It's working fine(by Replication).
Now added a new data element for Payment Block Indicator(DZAHLS) which is not predefined in "Maintain value mapping fields".But it's not working.
Because BAdi(MDG_CODE_LIST_PROVIDER) is not implemented for this data element.This BAdi only for 'SAP internal' not for custom name space.
Thanks,
Bala
