• What is the cause and solution for SAP error message UPF040 - Planning sequence &1 is defined recursively ?

  The SAP error message UPF040 indicates that a planning sequence is defined recursively, which means that the sequence is set up in such a way that it refers back to itself, creating a loop. This can lead to infinite loops during planning runs and is not allowed in the system.
  Cause:
  The recursive definition typically occurs when:
  
  A planning sequence is configured to call itself directly or indirectly through other sequences.
  There are circular dependencies in the planning sequence definitions.
  
  Solution:
  To resolve the UPF040 error, you can follow these steps:
  
  
  Review Planning Sequence Configuration:
  
  Go to the configuration of the planning sequence that is causing the error.
  Check the sequence for any direct references to itself.
  
  
  
  Check Dependencies:
  
  Look for any indirect references that may lead back to the original sequence.
  Ensure that no other planning sequences that are called within the current sequence also reference the original sequence.
  
  
  
  Modify the Sequence:
  
  If you find a recursive reference, modify the planning sequence to eliminate the recursion.
  You may need to redesign the planning logic to ensure that sequences are called in a linear fashion without circular dependencies.
  
  
  
  Test the Changes:
  
  After making the necessary changes, test the planning sequence to ensure that it runs without errors.
  
  
  
  Documentation:
  
  Document the changes made to the planning sequence for future reference and to help others understand the configuration.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like C223 (for planning sequence) or CPI1 (for planning sequence overview) to access and modify planning sequences.
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to planning sequences and this specific error message.
  Consult Documentation: Refer to SAP documentation or help guides for detailed information on configuring planning sequences and avoiding recursive definitions.
  
  By following these steps, you should be able to resolve the UPF040 error and ensure that your planning sequences function correctly without recursion.
