Smart SAP Assistant

• What is the cause and solution for SAP error message /STTPEC/MC_MD079 - Other materials exist using the same GTIN with different base UoM &1 ?

  The SAP error message /STTPEC/MC_MD079 indicates that there are multiple materials in the system that share the same Global Trade Item Number (GTIN) but have different base units of measure (UoM). This can lead to confusion in inventory management, sales, and logistics processes, as the GTIN is intended to uniquely identify a product.
  Cause:
  
  Duplicate GTIN Assignment: Different materials have been assigned the same GTIN, which is not allowed if they have different base units of measure.
  Incorrect Material Master Data: The material master records may have been incorrectly set up, leading to multiple entries with the same GTIN but different UoMs.
  Data Migration Issues: If data was migrated from another system, it’s possible that the GTINs were not properly validated, resulting in duplicates.
  
  Solution:
  
  Identify Duplicate Materials: Use transaction codes like SE16 or SE11 to query the material master table (MARA) and identify all materials that share the same GTIN.
  Review Material Master Data: Check the material master records for the identified materials to confirm their base UoM and GTIN.
  Correct the Data:
  
  If the materials are indeed different products, consider assigning unique GTINs to each material.
  If they are the same product, consolidate them into a single material record with the correct UoM.
  
  
  Update GTINs: If necessary, update the GTINs in the material master records to ensure that each GTIN is unique to a specific material and its base UoM.
  Consult with Business Stakeholders: Engage with relevant stakeholders (e.g., product management, sales, logistics) to ensure that the changes align with business processes and requirements.
  
  Related Information:
  
  GTIN: The Global Trade Item Number is a unique identifier for products, often used in barcodes.
  Base Unit of Measure (UoM): This is the unit in which the material is managed in inventory and sales processes.
  Material Master Data: This is a central repository of information related to materials in SAP, including descriptions, units of measure, and other attributes.
  SAP Transactions: Familiarize yourself with relevant SAP transactions such as MM01 (Create Material), MM02 (Change Material), and MM03 (Display Material) for managing material master data.
  
  Preventive Measures:
  
  Implement data validation rules to prevent the assignment of duplicate GTINs in the future.
  Regularly audit material master data to ensure compliance with GTIN and UoM standards.
  Train users on the importance of maintaining unique GTINs and correct UoM assignments in the material master.
  
  By addressing the root cause of the error and ensuring proper data management practices, you can resolve the issue and prevent it from recurring in the future.
