• What is the cause and solution for SAP error message WSTRN088 - Select a prepack line ?

  SAP Error Message:
  
  WSTRN088 - Select a prepack line
  
  Cause:
  The error message WSTRN088 typically occurs in the context of SAP Warehouse Management (WM) or Extended Warehouse Management (EWM) when handling prepack handling units or during the picking/packing process. It indicates that the system expects the user to select a specific prepack line (a handling unit or a packaging specification line) but none has been selected.
  This usually happens because:
  
  The process involves handling prepacks (pre-packaged sets of products), and the system requires the user to specify which prepack line to process.
  The user has not selected or confirmed the prepack line in the transaction or screen.
  The prepack line is mandatory for the next step in the process (e.g., picking, packing, or posting goods issue).
  
  
  Solution:
  To resolve the WSTRN088 error:
  
  
  Select the Prepack Line:
  
  On the relevant screen (e.g., during picking or packing), ensure that you explicitly select the prepack line.
  This might be a line item representing a prepackaged handling unit or a packaging specification.
  
  
  
  Check the Handling Unit or Prepack Setup:
  
  Verify that the prepack configuration is correct in the system.
  Ensure that the prepack lines are properly maintained in the packaging specifications or handling unit types.
  
  
  
  Follow the Process Flow:
  
  Make sure you follow the correct process steps in the transaction.
  If the system prompts for a prepack line, do not skip this step.
  
  
  
  User Training:
  
  Train users to recognize when a prepack line selection is required.
  Provide guidance on how to select the correct prepack line.
  
  
  
  Technical Checks (if needed):
  
  If the error persists despite selecting a prepack line, check for any custom enhancements or user exits that might interfere.
  Review the configuration of the warehouse process type or packaging specifications.
