SAP Error Message - Details

• Message type: E = Error

• Message class: MDG_BS_BP_DATAREPL - Messages for Business Partner Data Replication

• Message number: 020

• Message text: A fatal error occurred when processing partner &1

What causes this issue?

During the bulk inbound processing for business partners checks are
applied. If possible, errors found for a single business partner are
passed to 'Forward Error Handling' . Such errors do not imply a complete
rollback of the bulk message. Reprocessing for the faulty business
partners is possible with the Postprocessing Desktop.
However some erros which are found at a very late stage of inbound
processing cannot be handled with Forward Error Handling. They result in
a complete ROLLBACK of the processing to ensure data consistency.

System Response

The bulk message has been rejected.
