MDG_BS_ECC_SUPPLIER020 - Details

• The SAP error message MDG_BS_ECC_SUPPLIER020 indicates that there is a key mapping issue between a supplier and an identical entity in the system. This typically occurs in the context of Master Data Governance (MDG) for suppliers when there is a need to establish a relationship between a supplier record and another entity that is considered identical (e.g., a vendor or customer record).
  
  Cause:

  Configuration Issues: The configuration settings for key mapping in the MDG system may not be set up
