• What is the cause and solution for SAP error message CPWB214 - Only locked task list headers can be classified ?

  The SAP error message CPWB214 ("Only locked task list headers can be classified") typically occurs in the context of the SAP Production Planning (PP) module, particularly when working with task lists (such as routing or production versions) in the Classification system.
  Cause:
  This error message indicates that you are trying to classify a task list header that is not locked. In SAP, task lists must be locked before they can be classified. This is a safety measure to prevent changes to the task list while it is being classified, ensuring data integrity.
  Solution:
  To resolve this error, you need to ensure that the task list header you are trying to classify is locked. Here are the steps you can follow:
  
  
  Lock the Task List Header:
  
  Navigate to the transaction code for the task list you are working with (e.g., CA01 for routing).
  Open the task list header you want to classify.
  Lock the task list by using the appropriate function (usually there is a lock icon or a menu option to lock the task list).
  
  
  
  Classify the Task List:
  
  Once the task list header is locked, attempt to classify it again using the classification transaction (e.g., CL02 for classifying objects).
  
  
  
  Check Authorizations:
  
  Ensure that you have the necessary authorizations to lock and classify task lists. If you do not have the required permissions, contact your SAP administrator.
  
  
  
  Review Task List Status:
  
  Make sure that the task list is in a status that allows it to be locked and classified. If the task list is in a status that prohibits changes, you may need to change its status first.
