CY402 - Details

• The SAP error message CY402: Operation is already dispatched typically occurs in the context of production planning and control, particularly when dealing with production orders or operations in a manufacturing environment. This error indicates that an operation you are trying to process has already been dispatched, meaning it has already been scheduled for execution or is currently being worked on.
  Causes:
  
  Duplicate Dispatching: The operation has already been dispatched, and you are attempting to dispatch it again.
  Status Conflicts: The status of the operation may not allow for further dispatching (e.g., it may be in a status that indicates it is already in progress).
  System Errors: There may be inconsistencies in the database or issues with the transaction that led to the operation being marked as dispatched erroneously.
  
  Solutions:
  
  Check Operation Status: Verify the status of the operation in the production order. If it is already dispatched, you may not need to dispatch it again.
