• What is the cause and solution for SAP error message GPSC027 - UoM-conversion from & to & failed ?

  The SAP error message GPSC027 indicates that there is a failure in the unit of measurement (UoM) conversion between two different units. This typically occurs in scenarios where a conversion is required, such as in inventory management, sales orders, or production orders, and the system is unable to perform the conversion due to various reasons.
  Causes of GPSC027 Error
  
  
  Missing Conversion Factors: The conversion factors between the two units of measurement may not be defined in the system. If SAP does not have the necessary information to convert from one UoM to another, it will trigger this error.
  
  
  Incorrect UoM Configuration: The units of measurement may not be correctly configured in the system. This can include issues with the UoM type, decimal places, or other related settings.
  
  
  Inconsistent UoM Usage: The error can occur if there is an inconsistency in how units of measurement are used across different documents or master data. For example, if a material is defined with one UoM in the material master but is being used with another UoM in a transaction.
  
  
  Data Entry Errors: Manual data entry errors can lead to incorrect UoM being used in transactions, which can cause conversion failures.
  
  
  Solutions to GPSC027 Error
  
  
  Check UoM Configuration:
  
  Go to the transaction code CUNI (Unit of Measure Conversion) to check if the conversion factors between the two units are defined.
  Ensure that the UoM types and conversion factors are correctly set up.
  
  
  
  Define Missing Conversion Factors:
  
  If the conversion factors are missing, you can define them in the same transaction (CUNI). Make sure to include the correct source and target UoM along with the conversion factor.
  
  
  
  Review Material Master Data:
  
  Check the material master data (transaction code MM03) to ensure that the UoM settings are correct and consistent. Look for the base unit of measure and any alternative units of measure.
  
  
  
  Validate Transaction Data:
  
  Review the transaction data where the error occurred. Ensure that the UoM used in the transaction matches the UoM defined in the material master.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for additional guidance on UoM configuration and troubleshooting.
  
  
  
  Contact SAP Support:
  
  If the issue persists after checking the above points, consider reaching out to SAP support for further assistance.
