• What is the cause and solution for SAP error message /STTPEC/MC_MD075 - GTIN &1 is already used in material &2. Registration code mismatch. &3/&4 ?

  The SAP error message /STTPEC/MC_MD075 indicates that there is a conflict with the Global Trade Item Number (GTIN) being used in the system. Specifically, the error states that the GTIN is already associated with another material, and there is a registration code mismatch. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  GTIN Duplication: The GTIN you are trying to assign to a material is already assigned to another material in the system. GTINs must be unique identifiers for products.
  Registration Code Mismatch: The registration code associated with the GTIN does not match the expected value for the material you are trying to create or modify. This could be due to incorrect data entry or configuration issues.
  
  Solution:
  
  
  Check Existing GTINs: 
  
  Use transaction codes like MM03 (Display Material) or MM02 (Change Material) to check which material is currently using the GTIN in question.
  If the GTIN is indeed assigned to another material, you will need to either use a different GTIN or remove it from the existing material if it is no longer needed.
  
  
  
  Verify Registration Codes:
  
  Ensure that the registration code you are using matches the one that is expected for the GTIN. This may involve checking the configuration settings in the system or consulting with your data management team.
  
  
  
  Data Cleanup:
  
  If there are discrepancies in the data, you may need to clean up the material master records to ensure that GTINs and registration codes are correctly assigned.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP support team for specific guidelines on managing GTINs and registration codes.
  
  
  
  Use Unique GTINs:
  
  If you are creating new materials, ensure that you are using unique GTINs that are not already in use within the system.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on managing GTINs.
  Material Master Data Management: Familiarize yourself with best practices for managing material master data in SAP, including GTIN assignment and registration code management.
  Training and Support: If you are frequently encountering this issue, consider additional training for users involved in material master data management to prevent future occurrences.
  
  By following these steps, you should be able to resolve the error and ensure that your GTINs and registration codes are correctly managed within your SAP system.
