Replication of Supplier from ERP to SUS

Hi,

I am trying to replicate suppliers from ERP (ECC) to SUS system ( Classic Scenario). I have done all technical settings. When I run BD14, I am getting successful outbound IDOC from ECC. (There is no PI/XI but ECC connected to SUS via RFC.). I am getting error in SUS for Inbound IDOC "Basic type CREMAS05 does not exist" and "External segment name E2LFA1M002 cannot be interpreted". Ans vendor's are not replicated to SUS Vendor root.

Di you anyone know, reason for this inbound IDOC error? And is it mandatory to replicate suppliers from ERP to SUS?

Any help is appreciated.

Thanks ,
