CF226 - Details

• The SAP error message CF226, "You cannot delete a PRT of a referenced task list," typically occurs when you attempt to delete a Production Resource Tool (PRT) that is linked to a task list that is currently being referenced in a production order or another related object. This is a safeguard in SAP to prevent inconsistencies in production planning and execution.
  
  Cause:
  
  Referenced Task List: The PRT you are trying to delete is associated with a task list that is currently in use or referenced by a production order.
  Active Production Orders: If there are active production orders that utilize the task list containing the PRT, the system will prevent deletion to maintain data integrity.
  Dependencies: The PRT may have dependencies or relationships with other objects in the system that prevent its deletion.
  
  
  Solution:
  
  Check References: Before attempting to delete the PRT, check if it is being used in any active production orders or task lists.
