  Check for Data Consistency: Use transaction codes like /SAPAPO/TS (for checking the consistency of the planning area) to identify any inconsistencies in the data.
  Re-run the Planning Run: After addressing any issues found in the above steps, try re-running the planning run to see if the error persists.
