• What is the cause and solution for SAP error message MPLAN519 - Unit of measurement &1 not in table MMPT ?

  The SAP error message MPLAN519 indicates that the unit of measurement (UoM) specified in the system is not found in the table MMPT (which contains the valid units of measurement for materials). This error typically occurs during planning or when trying to create or modify a material master record.
  Cause:
  
  Invalid Unit of Measurement: The UoM you are trying to use is not defined in the system or is not valid for the material type you are working with.
  Missing Configuration: The unit of measurement may not have been set up correctly in the system, or it may have been deleted or deactivated.
  Data Entry Error: There might be a typographical error in the UoM being entered.
  
  Solution:
  
  
  Check UoM in MMPT:
  
  Go to transaction code SE11 (Data Dictionary) and check the table MMPT to see if the UoM exists.
  If it does not exist, you will need to create it.
  
  
  
  Create or Modify UoM:
  
  If the UoM is missing, you can create it using transaction code CUNI (Unit of Measure Conversion) or OMS2 (Maintain Units of Measure).
  Ensure that the UoM is correctly defined and linked to the appropriate material types.
  
  
  
  Verify Material Master Data:
  
  Check the material master data for the material in question using transaction code MM03 (Display Material).
  Ensure that the UoM is correctly assigned in the basic data view or the purchasing view.
  
  
  
  Check Configuration:
  
  If you have access, check the configuration settings in the customizing (transaction code SPRO) to ensure that the UoM is properly configured for the relevant material types and plants.
  
  
  
  Data Entry:
  
  Double-check the UoM being entered for any typographical errors. Ensure that it matches the UoM defined in the system.
  
  
  
  Related Information:
  
  Table MMPT: This table contains the valid units of measurement for materials. You can view it to see all the UoMs that are currently defined in the system.
  Transaction Codes:
  
  CUNI: For unit of measure conversion.
  OMS2: For maintaining units of measure.
  MM03: For displaying material master data.
