• What is the cause and solution for SAP error message RSAU279 - Unit of the source key figure was adjusted to unit in the IO repository ?

  The SAP error message RSAU279 indicates that there is a mismatch between the unit of measure (UoM) of a key figure in your data source and the unit defined in the InfoObject (IO) repository. This typically occurs during data loading or transformation processes in SAP BW (Business Warehouse) or SAP BW/4HANA.
  Cause:
  
  Unit Mismatch: The key figure in the source system has a different unit of measure than what is defined in the InfoObject in the BW system.
  Data Source Configuration: The data source may not be correctly configured to handle the units of measure.
  Transformation Rules: The transformation rules may not be set up to convert or handle the units appropriately.
  
  Solution:
  
  
  Check InfoObject Settings: 
  
  Go to the InfoObject in the BW system and verify the unit of measure defined for the key figure. Ensure it matches the unit of measure used in the source system.
  
  
  
  Adjust Data Source:
  
  If the source system's key figure has a different unit, you may need to adjust the data source or the extraction logic to ensure that the correct unit is being used.
  
  
  
  Modify Transformation:
  
  Review the transformation rules for the data load. If necessary, add logic to convert the units from the source to the target unit defined in the InfoObject.
  
  
  
  Data Load Monitoring:
  
  Monitor the data load process to ensure that the adjustments have resolved the issue. Check for any further error messages or warnings.
  
  
  
  Testing:
  
  After making changes, perform a test data load to confirm that the error has been resolved and that the data is being loaded correctly with the appropriate units.
