  Review Planning Parameters: Check the planning parameters and settings in the APO system to ensure that they are correctly configured. This includes reviewing the sequence of operations and ensuring they align with the expected planning logic.
  Analyze the Planning Run: Use transaction codes like /SAPAPO/SDP94 (for planning book) or /SAPAPO/MC90 (for monitoring) to analyze the planning run and identify where the sequence error is occurring.
  Re-run the Planning Process: After making necessary corrections to the master data or configuration, re-run the planning process to see if the error persists.
