• What is the cause and solution for SAP error message /ISDFPS/FDP442 - Operation/exercise '&' has already started and cannot be moved ?

  The SAP error message /ISDFPS/FDP442 indicates that an operation or exercise in the context of SAP's Flexible Planning (often used in production planning and control) has already started and cannot be moved. This typically occurs when there is an attempt to change the scheduling or planning of an operation that is already in progress.
  Cause:
  
  Operation Already Started: The primary cause of this error is that the operation or exercise you are trying to move has already begun. In SAP, once an operation starts, it is locked for changes to prevent inconsistencies in planning and execution.
  Incorrect Planning Sequence: If the planning sequence is not followed correctly, it may lead to attempts to move operations that are already active.
  Data Integrity Constraints: SAP enforces data integrity rules that prevent changes to operations that could lead to conflicts or inconsistencies in the production process.
  
  Solution:
  
  Check Operation Status: Verify the status of the operation or exercise. If it has indeed started, you will need to wait until it is completed before making any changes.
  Review Planning Sequence: Ensure that you are following the correct planning sequence. If you need to adjust the schedule, consider doing so for operations that have not yet started.
  Use Alternative Methods: If you need to adjust the planning, consider using alternative methods such as creating a new operation or exercise that reflects the desired changes instead of moving the existing one.
  Consult with Production Team: If the operation must be moved for operational reasons, consult with the production team to understand the implications and whether it is feasible to stop the current operation (if applicable).
  SAP Notes and Documentation: Check SAP Notes or documentation for any specific guidance related to this error message. There may be updates or patches that address similar issues.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP that pertain to production planning, such as CO01 (Create Production Order), CO02 (Change Production Order), and CO03 (Display Production Order).
  SAP Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP support for assistance. They may provide insights based on the specific configuration of your SAP system.
  User Permissions: Ensure that you have the necessary permissions to make changes to operations in the system, as restrictions may also lead to errors.
  
  By following these steps, you should be able to address the error message and understand the underlying issues related to operation scheduling in SAP.
