MDG Vendor synchronization issue

Hi,

I  am trying to create vendor using Vendor ERP UI. The Business partner are getting created after approval  process is complete. The vendors are not getting created. i am facing the below error during replication.

'No object type code assigned to entity type ADDRNO of data model BP'.

I have maintained the below prefixs as well.

Data Model = BP, Entity Type = ADDRNO => Prefix $ (where ADDRNO is the address number)

Data Model = BP, Entity Type = BP_HEADER => Prefix $ (where BP_HEADER is the supplier number).

Can you please share your inputs in  resolving this issue.

Thanks,

Nagendra.
