This error indicates that there is an issue with the conversion of volume units during planning processes.
  Causes:

This can happen if the unit of measure used in the planning data does not match the expected unit of measure in the master data or if there are inconsistencies in the conversion factors.
  
  
  Master Data Issues: If the material master data or the location master data has incorrect or incomplete unit of measure settings, it can lead to conversion errors.
  
  
  Data Inconsistencies: Inconsistencies in the data, such as different units of measure being used across different planning books or data sources, can also trigger this error.
  
  
  Custom Code or Enhancements: If there are custom developments or enhancements in the planning process that manipulate units of measure, they may not handle conversions correctly.

  Data Consistency Checks:
  
  Run consistency checks in the APO system to identify any discrepancies in the data.
  Use transaction codes like /SAPAPO/TS to check for inconsistencies in the planning books.
