  SAP Error Message:
  WXPB218 - Function cannot be executed in lead columns
  
  
  Cause:
  This error occurs when a user tries to execute a function or action on a "lead column" in an ALV (ABAP List Viewer) grid or a similar SAP UI element where such operations are restricted. Lead columns are typically the first columns in a table or grid that serve as identifiers or key fields, and certain functions (like sorting, filtering, or specific context menu actions) are not allowed on these columns to maintain data integrity or UI consistency.
  
  Explanation:
  
  Lead columns are special columns in ALV grids or SAP tables that often contain key or primary data.
  Some functions (e.g., certain toolbar buttons, context menu options, or user commands) are disabled or not applicable on these columns.
  Attempting to execute these functions on lead columns triggers the WXPB218 message.
  
  
  
  Solution:
  
  
  Avoid executing the function on lead columns:
  Ensure that the function or action is performed on non-lead
