• What is the cause and solution for SAP error message MDG_BS_ECC_SUPPLIER012 - Exit; user recognized current supplier as duplicate ?

  The SAP error message MDG_BS_ECC_SUPPLIER012 indicates that the system has identified a potential duplicate supplier during the data governance process in SAP Master Data Governance (MDG). This error typically occurs when a user attempts to create or change a supplier record, and the system recognizes that the supplier being processed is similar to an existing supplier in the system.
  Cause:
  The primary cause of this error is that the system has a duplicate check mechanism in place to prevent the creation of duplicate supplier records. The criteria for identifying duplicates can include various attributes such as:
  
  Supplier name
  Tax identification number
  Address details
  Contact information
  
  When the system detects that the new or modified supplier data closely matches an existing supplier record, it triggers this error message to alert the user.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Existing Suppliers: Check the existing supplier records in the system to confirm whether the supplier you are trying to create or modify is indeed a duplicate. You can use transaction codes like BP (Business Partner) or MK01 (Create Vendor) to search for existing suppliers.
  
  
  Modify the Supplier Data: If you find that the supplier is a duplicate, you may need to modify the data you are trying to enter to ensure it is unique. This could involve changing the supplier name, address, or other identifying information.
  
  
  Merge Records: If the supplier is indeed a duplicate, consider merging the records if your business process allows for it. This can help maintain data integrity and avoid confusion.
  
  
  Adjust Duplicate Check Settings: If you believe the duplicate check is too strict or not applicable for your scenario, you may need to adjust the duplicate check settings in the MDG configuration. This should be done with caution and typically requires the involvement of an SAP MDG consultant or administrator.
  
  
  Consult Documentation: Refer to the SAP documentation or help resources for more detailed information on how to handle duplicate suppliers and the specific configuration settings related to duplicate checks.
  
  
  User Training: Ensure that users are trained on how to properly enter supplier data and understand the importance of maintaining unique records to avoid such errors in the future.
