MDG_BS_ECC_CUST006 - Details

• The SAP error message MDG_BS_ECC_CUST006 indicates that the Data Replication Framework (DRF) is configured to use non-harmonized keys for customer data in the specified client system. This typically occurs in the context of SAP Master Data Governance (MDG) when there is a mismatch in the key configuration for customer master data between the MDG system and the connected ECC (or S/4HANA) system.
  
  Cause:
  
  Non-Harmonized Keys: The error arises when the customer master data is set up to use non-harmonized keys, meaning that the keys used in the MDG system do not match the keys expected in the target ECC system.
  
  Configuration Issues: There may be a configuration issue in the DRF settings, where the key mapping for customer data is not properly defined.
  Inconsistent Data Model: The data model in the MDG system may not align with the data model in the ECC system, leading to discrepancies in how customer data is identified and
