  SAP Error Message: WFCS203
  
  Message Text: List display: ALV grid
  
  1. Cause
  The error message WFCS203 typically appears in SAP Workflow when the system tries to display a list using the ALV (ABAP List Viewer) grid control, but encounters an issue. This can happen due to:
  
  Missing or incorrect ALV grid control setup in the workflow container or the workflow step.
  The ALV grid control is not properly initialized or the required ALV function modules/classes are not called correctly.
  The frontend (SAP GUI) does not support the ALV grid control or the control is not available in the current environment.
  Authorization or system configuration issues preventing the ALV grid from being displayed.
  The workflow container element expected to be displayed as an ALV grid is empty or not properly populated.
  
  
  2. Solution
  To resolve the WFCS203 error, consider the following steps:
  
  
  Check Workflow Container:
  
  Verify that the container element intended for ALV display contains the correct internal table or data structure suitable for ALV grid display.
  
  
  Ensure ALV Grid Control is Supported:
  
  Confirm that the SAP GUI version supports ALV grid controls. Older or limited SAP GUI versions might not support ALV grid display.
  
  
  Review Workflow Step Configuration:
  
  In the workflow step where the ALV grid is displayed, check the method or function module used to display the list. Make sure it uses the correct ALV function modules or classes (e.g., CL_GUI_ALV_GRID).
  
  
  Check Authorization:
  
  Ensure the user has the necessary authorizations to display ALV grids and execute related function modules.
  
  
  Debug the Workflow:
  
  Use transaction SWI1 or SWI2_DIAG to trace the workflow and identify where the error occurs. Debug the ABAP code or method that triggers the ALV display.
  
  
  Update or Patch SAP GUI:
  
  If the issue is due to frontend limitations, update the SAP GUI to a version that supports ALV grid controls.
