• What is the cause and solution for SAP error message APB_FPM_CORE324 - No transaction handler class has been maintained ?

  The SAP error message APB_FPM_CORE324 indicates that there is no transaction handler class maintained for a specific application or configuration in the Floorplan Manager (FPM). This error typically arises when the FPM application is trying to execute a transaction but cannot find the corresponding handler class that is supposed to manage the transaction.
  Cause:
  
  Missing Configuration: The transaction handler class has not been defined in the FPM configuration.
  Incorrect Configuration: The configuration might be pointing to a non-existent or incorrect handler class.
  Transport Issues: If the application was transported from one system to another, the handler class might not have been included in the transport.
  Development Errors: There may be issues in the development environment where the handler class was not properly implemented or activated.
  
  Solution:
  
  
  Check FPM Configuration:
  
  Go to the FPM configuration in the SAP system (transaction code FPM).
  Verify that the transaction handler class is correctly defined in the configuration settings.
  Ensure that the handler class is assigned to the correct application.
  
  
  
  Maintain Transaction Handler Class:
  
  If the handler class is missing, you need to create or maintain it. This can be done in the FPM configuration settings.
  You can use transaction code SE80 to navigate to the relevant package and create or modify the handler class.
  
  
  
  Check for Transport Issues:
  
  If the application was transported, ensure that all necessary objects, including the handler class, were included in the transport request.
  Check the transport logs for any errors or missing objects.
  
  
  
  Debugging:
  
  If you have access to the development environment, you can debug the application to see where it is failing to find the handler class.
  Use transaction SE37 to check if the function module associated with the handler class is available and functioning correctly.
