• 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
