• What is the cause and solution for SAP error message WR_POWL002 - Select only one table line ?

  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).
  Certain actions (like "Change", "Display", or "Edit") are designed to work on a single object at a time.
  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 items one by one.
  If the error occurs despite selecting one line, it might be a UI or POWL configuration issue; try refreshing the list or restarting the session.
  
  
  Related Information:
  
  This message is common in SAP Fiori apps or SAP GUI transactions that use POWL.
  Check the POWL configuration if you are a developer or administrator to ensure the action’s selection mode is set correctly.
  Sometimes, custom POWL queries or actions might not handle multi-selection properly, requiring adjustment in the underlying code or configuration.
  SAP Note references for POWL errors can be checked via SAP Support Portal if the problem persists.
  
  
  Summary:
  
  WR_POWL002 means you must select exactly one line in the POWL list to proceed. Select one item and retry the action.
