IDOC CREMAS04 for vendor master data

We use a third party to maintain our vendor master information and they send us XML messages for vendor master data to our PI system 7.31.

If I map the vendor master XML message to IDOC CREMAS message type CREMAS04, will the IDOC CREMAS04 itself be enough to create or update the vendor master data in ECC?

Our current ECC system is SAP 701.

Do I still need to create the ADRMAS IDOC?

Thanks!
