• What is the cause and solution for SAP error message WWP1026 - Only one object can be selected to be refreshed ?

  SAP Error Message:
  
  WWP1026 - Only one object can be selected to be refreshed
  
  Cause:
  This error occurs in SAP Web Dynpro applications when a user or a program tries to refresh multiple UI elements (objects) simultaneously, but the framework or the specific method being called only supports refreshing one object at a time.
  In other words, the refresh operation is designed to handle a single UI element (like a UI container, view, or component) per call, and passing multiple objects or a collection of objects to the refresh method triggers this error.
  
  When does it typically occur?
  
  When calling the wd_this->refresh() or wd_component->refresh() method with multiple objects.
  When trying to refresh multiple UI elements in one go, for example, passing an internal table or multiple references instead of a single UI element.
  In custom Web Dynpro code where the developer attempts to refresh more than one UI element simultaneously.
  
  
  Solution:
  
  
  Refresh one object at a time: Modify the code to refresh each UI element individually in a loop rather than passing multiple objects at once.
  Example:
  LOOP AT lt_ui_elements INTO DATA(lo_ui_element).
    lo_ui_element->refresh( ).
  ENDLOOP.
  
  
  Check the method signature: Ensure that the refresh method is called with a single object reference, not a table or multiple references.
  
  
  Review the UI element references: Confirm that the object passed to the refresh method is a valid single UI element (like a view or UI container).
  
  
  
  Related Information:
  
  SAP Web Dynpro Framework: The refresh method is used to update the UI element to reflect the latest data or state.
  Documentation: SAP Web Dynpro ABAP Programming Guide explains the usage of the refresh method and its limitations.
  Debugging: Use the debugger to check what object(s) are being passed to the refresh method when the error occurs.
  SAP Notes: Sometimes SAP releases notes or patches if this error is caused by a framework bug, so check the SAP Support Portal for relevant notes.
  
  
  Summary:
  
  Cause: Attempting to refresh multiple UI objects at once, but only one is allowed.
  Solution: Refresh UI elements one by one.
  Check: Code logic and method calls to ensure only a single UI element is refreshed per call.
