• What is the cause and solution for SAP error message APB_FPM_CORE205 - Changing the target subview only allowed while view-switch event ?

  The SAP error message APB_FPM_CORE205 typically occurs in the context of SAP FPM (Floorplan Manager) applications when there is an attempt to change the target subview outside of a view-switch event. This error indicates that the application is trying to switch views or subviews in a manner that is not permitted by the framework at that particular point in time.
  Cause:
  The error is caused by trying to change the target subview in a way that is not aligned with the expected lifecycle of the FPM application. Specifically, it usually happens when:
  
  The application is not in a state that allows for a view switch.
  The view-switch event is not triggered, which is necessary for changing the subview.
  There may be issues with the event handling or the sequence of operations in the application.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Event Handling: Ensure that the logic for changing the subview is correctly placed within the appropriate event handlers. The view-switch should be triggered by a specific event (like a button click or a selection change).
  
  
  Use the Correct API: Make sure you are using the correct API methods to change the subview. The method should be called in response to a view-switch event.
  
  
  Debug the Application: Use debugging tools to trace the flow of events in your application. Check if the view-switch event is being fired as expected and if the application state allows for a subview change.
  
  
  Review Configuration: Check the configuration of your FPM application. Ensure that the views and subviews are correctly defined and that there are no misconfigurations that could prevent the view-switch event from being recognized.
  
  
  Consult Documentation: Refer to the SAP documentation for FPM to understand the lifecycle of views and the correct usage of view-switch events.
  
  
  Error Handling: Implement error handling in your application to gracefully manage situations where a view-switch cannot occur.
  
  
  Related Information:

  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have found.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to prevent it from occurring in your SAP FPM application.
