• What is the cause and solution for SAP error message MSI_ECC019 - the order unit &1 and base unit &2 are same ?

  The SAP error message MSI_ECC019 indicates that there is a mismatch between the order unit and the base unit of measure for a material in the system. Specifically, the error states that the order unit and the base unit are the same, which is not allowed in certain contexts within SAP.
  Cause:
  This error typically occurs in the following scenarios:
  
  Material Master Configuration: The material master record has been set up incorrectly, where the order unit (the unit used for ordering) is defined to be the same as the base unit of measure (the unit in which the material is stored and managed).
  Transaction Context: The error may arise during transactions such as creating purchase orders, sales orders, or inventory management activities where the system expects different units for ordering and base measurement.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03).
  Check the "Basic Data" and "Purchasing" views for the material in question.
  Ensure that the order unit (in the Purchasing view) is different from the base unit of measure (in the Basic Data view).
  
  
  
  Adjust the Order Unit:
  
  If the order unit is indeed the same as the base unit, you will need to change the order unit to a different unit that makes sense for your business processes.
  You can do this by using transaction code MM02 to modify the material master record.
  
  
  
  Review Configuration:
  
  If you are unsure about the appropriate units to use, consult with your SAP functional team or a business analyst to ensure that the units align with your business requirements.
  
  
  
  Test the Changes:
  
  After making the necessary adjustments, try to perform the transaction again to see if the error persists.
  
  
  
  Related Information:
  
  Unit of Measure (UoM): In SAP, the base unit of measure is the primary unit in which the material is managed, while the order unit is used for procurement and sales. It is important to configure these correctly to avoid issues in transactions.
  SAP Documentation: Refer to SAP Help documentation for more details on material master data and unit of measure settings.
  Transaction Codes:
  
  MM03: Display Material Master
  MM02: Change Material Master
  MM01: Create Material Master
