  SAP Error Message:
  WD482 Table processing not allowed in asynchronous methods
  
  
  Cause:
  This error occurs when a Web Dynpro application tries to perform table processing (such as modifying or accessing internal tables in a way that requires synchronous context) inside an asynchronous method.
  
  Asynchronous methods in Web Dynpro are executed in a different processing context (background or parallel processing).
  Table processing operations (like modifying UI tables, or certain data manipulations tied to the UI context) are not allowed in asynchronous methods because the UI context and the internal table processing logic are designed to work synchronously.
  The framework restricts table processing in asynchronous methods to avoid inconsistencies and runtime errors.
  
  
  When does this typically happen?
  
  When you call wd_this->register_for_event or use asynchronous event handlers.
  When you try to update UI elements or internal tables bound to UI inside an asynchronous method.
  When you perform operations that require synchronous UI context inside
