  SAP Error Message:
  WX802 SYST: error inserting tab &
  
  Cause:
  
  The error WX802 typically occurs during the runtime of an SAP Web Dynpro application.
  It indicates that there was a problem inserting a tab into a tabstrip UI element.
  The placeholder & in the message is replaced by the name or index of the tab that failed to be inserted.
  Common causes include:
  
  The tabstrip UI element is not properly initialized or does not exist.
  The tab being inserted has invalid or missing properties (e.g., no ID, no label).
  The tab index or position is out of range.
  The UI component tree is in an inconsistent state.
  Programming errors in the Web Dynpro component or view controller.
  Issues with dynamic tab creation logic (e.g., trying to insert a tab multiple times or with duplicate IDs).
  
  
  
  
  Solution:
  
  
  Check Tabstrip Initialization:
  
  Ensure the tabstrip UI element is correctly defined in the Web Dynpro view layout.
  Verify that the tabstrip instance is properly instantiated before inserting tabs.
  
  
  
  Validate Tab Properties:
  
  Make sure each tab has a unique ID.
  Ensure the tab label and other required properties are set correctly.
  
  
  
  Review Tab Insertion Logic:
  
  Check the code where tabs are dynamically inserted.
  Confirm that the tab index or position is valid and within the allowed range.
  Avoid inserting the same tab multiple times.
  
  
  
  Debug the Web Dynpro Application:
  
  Use the Web Dynpro debugger to trace the point of failure.
  Check the component controller and view controller methods related to tab creation and insertion.
  
  
  
  Check for UI Component Tree Consistency:
  
  Sometimes, the UI component tree might be corrupted or inconsistent.
  Try to refresh or reinitialize the UI elements if possible.
