This can occur in various scenarios, such as during planning, data transfer, or when executing certain transactions.

  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Unit of Measure in APO:
  
  Go to the transaction code /SAPAPO/OM17 (Maintain Units of Measure).

  Check Master Data:
  
  Review the relevant master data (like material master) in the SAP ERP system to ensure that the UoM is correctly maintained there.
  Use transaction codes like MM03 (Display Material) to check the material master data.
