• What is the cause and solution for SAP error message EDEREG472 - Backup supplier is not unique ?

  The SAP error message EDEREG472: Backup supplier is not unique typically occurs in the context of supplier management or procurement processes within SAP. This error indicates that there are multiple backup suppliers defined for a particular material or service, and the system cannot determine which one to use.
  Cause:
  
  
  Multiple Backup Suppliers: The primary cause of this error is that more than one backup supplier has been assigned to a material or service in the system. When the system tries to process a transaction that requires a backup supplier, it finds multiple options and cannot proceed.
  
  
  Configuration Issues: There may be issues in the configuration of the supplier data or the material master data that lead to ambiguity in selecting a backup supplier.
  
  
  Data Entry Errors: Incorrect or duplicate entries in the supplier master data can also lead to this error.
  
  
  Solution:
  To resolve the EDEREG472 error, you can take the following steps:
  
  
  Check Supplier Data:
  
  Go to the supplier master data and check the list of backup suppliers assigned to the relevant material or service.
  Identify and review the backup suppliers to determine if there are duplicates.
  
  
  
  Remove Duplicates:
  
  If you find multiple backup suppliers, decide which one should be the primary backup supplier and remove or deactivate the others.
  You can do this by editing the supplier data in the relevant transaction (e.g., ME11 for creating or ME12 for changing a supplier).
  
  
  
  Review Material Master Data:
  
  Check the material master data (transaction MM03) to ensure that the backup supplier information is correctly maintained.
  Ensure that the backup supplier field is populated correctly and does not contain multiple entries.
  
  
  
  Consult Documentation:
  
  Review any relevant SAP documentation or guidelines regarding supplier management to ensure compliance with best practices.
  
  
  
  Testing:
  
  After making changes, test the transaction again to ensure that the error is resolved.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as ME11 (Create Vendor), ME12 (Change Vendor), and MM03 (Display Material) to manage supplier and material data.
