• What is the cause and solution for SAP error message /STTPEC/MC_MD076 - GTIN &1 is already used in material &2. National code type mismatch.&3/&4 ?

  The SAP error message /STTPEC/MC_MD076 indicates that there is a problem with the Global Trade Item Number (GTIN) being used in the system. Specifically, the error states that the GTIN is already associated with a different material, and there is a mismatch in the national code type. 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 for each material.
  National Code Type Mismatch: The error suggests that there is a mismatch in the expected national code type for the GTIN being used. This could be due to incorrect configuration or data entry.
  
  Solutions:
  
  
  Check Existing GTIN Assignments:
  
  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 National Code Type:
  
  Ensure that the national code type for the GTIN you are trying to use matches the expected type in your configuration. This may involve checking the settings in the material master or the relevant configuration settings in the SAP system.
  You can check the configuration for GTINs in the relevant customizing settings (SPRO) under Logistics > Material Management > Material Master > Basic Settings > Define National Codes.
  
  
  
  Consult with Your Team:
  
  If you are unsure about the GTIN assignments or the national code types, consult with your materials management or data governance team to ensure that you are following the correct procedures.
  
  
  
  Data Cleanup:
  
  If there are obsolete or incorrect GTINs in the system, consider cleaning up the data to avoid future conflicts. This may involve archiving or deleting materials that are no longer in use.
  
  
  
  SAP Notes and Documentation:
  
  Check for any relevant SAP Notes that may address this specific error or provide additional guidance. You can search for notes in the SAP Support Portal.
