SIPM integration to SAP ECC using MDG-S

Dear All,

We are working on to integrate Ariba SIPM to SAP ECC using MDG-S.

I have the following queries on it

• When vendors created in SIPM are replicated into SAP ECC, do they get stored in SAP ECC vendor master tables or to MDG-S specific tables ?
• If the vendors get stored in MDG-S tables, then how can they be updated in standard SAP ECC vendor master tables like LFA1 ?

Thanks in advance.
