• What is the cause and solution for SAP error message /STTPEC/MC_MD145 - Copying EAN to GTIN not possible for material &1 UoM &2. GTIN is invalid. ?

  The SAP error message /STTPEC/MC_MD145 indicates that there is an issue with copying the European Article Number (EAN) to the Global Trade Item Number (GTIN) for a specific material and unit of measure (UoM). The error specifically states that the GTIN is invalid, which can occur due to several reasons.
  Causes:
  
  Invalid GTIN Format: The GTIN must adhere to specific formats (e.g., GTIN-8, GTIN-12, GTIN-13, GTIN-14). If the GTIN does not conform to these standards, the system will reject it.
  Missing GTIN: The GTIN may not be assigned to the material in the system, leading to the inability to copy the EAN.
  Incorrect Material Master Data: The material master data may be incomplete or incorrectly configured, particularly in the area related to GTIN and EAN.
  Unit of Measure Issues: The unit of measure (UoM) associated with the material may not be compatible with the GTIN or may not be defined correctly in the system.
  Data Consistency Issues: There may be inconsistencies in the data between the EAN and GTIN fields, leading to validation errors.
  
  Solutions:
  
  Check GTIN Format: Verify that the GTIN is in the correct format and adheres to the required length (e.g., 8, 12, 13, or 14 digits).
  Assign GTIN: If the GTIN is missing, you need to assign a valid GTIN to the material in the material master record.
  Review Material Master Data: Go to the material master (transaction code MM03) and check the relevant views (e.g., Basic Data, Sales, and Distribution) to ensure that all necessary fields are filled out correctly.
  Validate UoM: Ensure that the unit of measure associated with the material is correctly defined and compatible with the GTIN.
  Data Consistency Check: Perform a consistency check on the material data to identify any discrepancies between the EAN and GTIN fields.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on GTIN and EAN management.
