• What is the cause and solution for SAP error message SWDP_WB_TOOL523 - UI element &1 needs action type NON_PHASE ?

  The SAP error message SWDP_WB_TOOL523 indicates that a UI element in your Web Dynpro application requires an action type of NON_PHASE, but it is currently set to a different type. This error typically arises during the development or configuration of Web Dynpro applications in SAP.
  Cause:
  The error occurs when a UI element (like a button or link) is expected to perform an action that does not require a round trip to the server (i.e., it should not be a phase action). Instead, it should be a non-phase action, which means it can be executed without the need for a full page refresh or server interaction. This is often the case for UI elements that are meant to trigger client-side actions or updates.
  Solution:
  To resolve this error, you need to check the properties of the UI element that is causing the issue. Here are the steps you can follow:
  
  
  Open the Web Dynpro Component: Go to the Web Dynpro component where the error is occurring.
  
  
  Locate the UI Element: Identify the specific UI element that is generating the error. This could be a button, link, or any other interactive element.
  
  
  Check Action Type: In the properties of the UI element, look for the action type setting. Ensure that it is set to NON_PHASE. If it is set to a different type (like PHASE), change it to NON_PHASE.
  
  
  Review Event Handlers: If the UI element is supposed to trigger an event, ensure that the event handler is correctly implemented and does not require a server round trip.
  
  
  Test the Application: After making the changes, test the application to ensure that the error is resolved and that the UI element behaves as expected.
