  • 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
