CREMDM inbound configuration. Vendor master

We are have a scenario for vendor master MDM-XI-ECC.

for this the IDOC used is CREMDM04.

I cannot find the process code for CREMD04 in ECC.

I tried CRE1, CRE2 but that gives error & it works fine for CREMAS.

Do we have to split CREMD04 into CREMAS & Address master in XI. Or is there any innbound program in ECC?

Thanks
