• What is the cause and solution for SAP error message APB_FPM_CORE023 - Main view &1 requires a subview ?

  The SAP error message APB_FPM_CORE023 indicates that a main view in a Floorplan Manager (FPM) application requires a subview to function properly. This error typically occurs when the configuration of the FPM application is incomplete or incorrect, specifically when the main view is not properly linked to a subview.
  Cause:
  
  Missing Subview Configuration: The main view is defined, but the corresponding subview is not configured or linked correctly.
  Incorrect View Hierarchy: The application may have an incorrect hierarchy where the main view expects a subview that is not defined.
  Transport Issues: If the application was transported from one system to another, the subview might not have been included in the transport request.
  
  Solution:
  
  
  Check Configuration:
  
  Go to the FPM configuration in the SAP system.
  Ensure that the main view is correctly linked to a subview. You can do this by checking the FPM configuration settings in the relevant application component.

  Ensure that the view hierarchy is correctly set up. The main view should have a defined subview that it can call.
  
  
  
  Transport Check:
  
  If the issue arose after a transport, verify that all necessary components (including the subview) were included in the transport request. If not, transport the missing components.
