• What is the cause and solution for SAP error message /STTPEC/MC_MD087 - GTIN &1 is already used in material &2. Business partner (Cust.) mismatch ?

  The SAP error message /STTPEC/MC_MD087 GTIN &1 is already used in material &2. Business partner (Cust.) mismatch typically occurs in the context of managing materials and their associated Global Trade Item Numbers (GTINs) in SAP. This error indicates that the GTIN you are trying to assign to a material is already in use for another material, but there is a mismatch in the business partner (customer) associated with that GTIN.
  Cause:
  
  Duplicate GTIN Assignment: The GTIN you are trying to assign is already linked to another material in the system.
  Business Partner Mismatch: The GTIN is associated with a different business partner (customer) than the one you are trying to use it with. This can happen if the GTIN is meant for a specific customer and you are trying to assign it to a different customer.
  
  Solution:
  
  
  Check Existing Assignments:
  
  Use transaction codes like MM03 (Display Material) or MM02 (Change Material) to check which material is currently using the GTIN.
  Verify the business partner associated with that GTIN.
  
  
  
  Change GTIN Assignment:
  
  If the GTIN is indeed already assigned to another material, you may need to either:
  
  Use a different GTIN that is not currently in use.
  Reassign the existing GTIN to the correct material if it is appropriate to do so.
  
  
  
  
  
  Update Business Partner Information:
  
  Ensure that the business partner information is correctly set up in the system. If the GTIN is meant for a specific customer, make sure you are working with the correct customer data.
  
  
  
  Consult with Your Team:
  
  If you are unsure about the implications of changing GTIN assignments or business partner information, consult with your SAP team or a business analyst to ensure compliance with business rules and data integrity.
