• What is the cause and solution for SAP error message MPE_EXEC_SFO120 - Unit conversion (from unit &2 to unit &3) for order &1 failed ?

  The SAP error message MPE_EXEC_SFO120 indicates that there is a problem with unit conversion when processing an order. Specifically, it suggests that the system is unable to convert a quantity from one unit of measure (UoM) to another for a specific order. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause
  
  
  Unit of Measure Configuration: The units involved in the conversion may not be properly defined in the system. This can happen if the units are not set up in the unit of measure table or if there are missing conversion factors.
  
  
  Missing Conversion Factors: If the conversion factors between the two units are not defined, the system will not be able to perform the conversion.
  
  
  Incompatible Units: The units being converted may not be compatible. For example, trying to convert between units that are not logically convertible (e.g., weight to volume) can lead to this error.
  
  
  Data Entry Errors: There may be errors in the data entry for the order, such as incorrect unit specifications.
  
  
  Solution
  
  
  Check Unit of Measure Configuration:
  
  Go to the transaction code CUNI (Maintain Units of Measure) in SAP.
  Verify that both units (&2 and &3) are defined in the system.
  Ensure that the units are correctly set up in the relevant tables.
  
  
  
  Define Conversion Factors:
  
  In the same transaction (CUNI), check if there are conversion factors defined between the two units.
  If not, you may need to create a new entry to define how one unit converts to the other.
  
  
  
  Review Order Data:
  
  Check the order (&1) for any discrepancies in the unit of measure fields.
  Ensure that the units used in the order are appropriate and correctly specified.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for specific details on unit conversions and any additional configuration that may be required.
  
  
  
  Testing:
  
  After making changes, test the order processing again to see if the error persists.
