• What is the cause and solution for SAP error message APB_FPM_CORE107 - Shared data component cannot be attached; it is already instantiated ?

  The SAP error message APB_FPM_CORE107 indicates that there is an issue with the attachment of a shared data component in the Floorplan Manager (FPM) framework. This error typically occurs when the system attempts to instantiate a shared data component that is already in use or instantiated elsewhere in the application.
  Cause:
  
  Multiple Instantiation: The most common cause of this error is that the shared data component is being instantiated multiple times in the same context or session.
  Configuration Issues: There may be a misconfiguration in the FPM application or the component settings that leads to the component being instantiated more than once.
  Session Management: If the application is not managing sessions properly, it may lead to conflicts with shared components.
  
  Solution:
  
  Check Component Instantiation: Review the FPM configuration and ensure that the shared data component is not being instantiated multiple times. Look for any duplicate entries in the configuration.
  Use Singleton Pattern: If applicable, ensure that the shared data component is designed to follow the singleton pattern, which allows only one instance of the component to exist.
  Review Application Logic: Check the application logic to ensure that the shared data component is being used correctly and that it is not being unnecessarily instantiated in different parts of the application.
  Clear Cache: Sometimes, clearing the application cache or restarting the application server can resolve issues related to stale instances.
  Debugging: Use debugging tools to trace the instantiation of the shared data component and identify where the multiple instantiations are occurring.
