WR_POWL002 - Details

• SAP Error Message:
  WR_POWL002 - Select only one table line
  
  
  Cause:
  This error occurs when a user tries to perform an action in a POWL (Personal Object Worklist) application but has selected either no line or multiple lines in the list instead of exactly one line. Many POWL actions require the user to select exactly one item to proceed, and selecting zero or more than one line violates this requirement.
  
  Explanation:
  
  POWL (Personal Object Worklist) is a framework in SAP that displays lists of business objects (e.g., purchase orders, workflow tasks).

  If the user selects multiple lines or none, the system cannot determine which object to process, hence the error.
  
  
  
  Solution:
  
  Select exactly one line in the POWL list before executing the action.
  If you want to process multiple items, check if the action supports multi-selection or batch processing. If not, process
