  Cause:
  
  Invalid Time Unit: The time unit specified in the configuration or transaction is not found in the standard tables T546T (Time Units) or T777L (Time Unit for Time Evaluation).
  Configuration Issues: There may be a misconfiguration in the time management settings, such as in the employee's time data or in the time evaluation settings.

  Solution:
  
  
  Check Time Unit Configuration:
  
  Go to transaction code SPRO and navigate to the following path:
  
  Personnel Management -> Time Management -> Time Data Recording and Administration -> Define Time Units.

  If you need to use a custom time unit, you may need to add it to the configuration.
  
  
  
  Check Employee Master Data:
  
  Review the employee master data to ensure that the time unit assigned is valid.
  Use transaction code PA30 to check the relevant infotypes (e.g., Infotype 0007 - Planned Working Time).
  
  
  
  Review Custom Code:
  
  If there are any custom programs or enhancements, review the code to ensure that it is not referencing an invalid time unit.
