  Solution:
  
  Refresh Data: If you encounter this error, try refreshing the data or reloading the planning view. This can help synchronize the changes made in the system.
  Check for Changes: Review the changes made to the precondition. You may need to check the change logs or audit trails to identify what was modified.
  Locking Mechanism: Ensure that proper locking mechanisms are in place to prevent concurrent modifications. This may involve coordinating with other users or teams.
  Re-evaluate Planning Parameters: If the precondition is related to specific planning parameters, ensure that they are correctly set and aligned with the current planning scenario.
