• What is the cause and solution for SAP error message /STTPEC/MC_MD074 - GTIN &1 is already used in material &2. National code mismatch. &3/&4 ?

  The SAP error message /STTPEC/MC_MD074 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, leading to a national code mismatch. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Duplicate GTIN: The GTIN you are trying to assign to a material is already assigned to another material in the system.
  National Code Mismatch: The GTIN may be associated with a different national code than the one you are trying to use, which can happen if the GTIN is registered in a different country or region.
  Data Entry Error: There may have been a mistake in entering the GTIN or material number, leading to confusion in the system.
  
  Solution:
  
  
  Check Existing Assignments:
  
  Use transaction codes like MM03 (Display Material) or MM02 (Change Material) to check which material is currently using the GTIN in question.
  Verify the GTIN and ensure it is not mistakenly assigned to another material.
  
  
  
  Correct the GTIN:
  
  If the GTIN is indeed already in use, you will need to either:
  
  Use a different GTIN that is not currently assigned to any material.
  If the GTIN is supposed to be associated with the material you are working on, you may need to remove it from the other material first.
  
  
  
  
  
  Review National Codes:
  
  Ensure that the national codes associated with the GTIN and the material match. If they do not, you may need to update the national code for the material or GTIN as appropriate.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP support team for specific guidelines on handling GTINs and national codes.
  
  
  
  Data Maintenance:
  
  Regularly maintain and audit your GTIN and material data to prevent such conflicts in the future.
