  The SAP error message /PM0/3FW_MESSAGES056 Not possible to create plug-in object; class &1 not available typically indicates that the system is unable to instantiate a plug-in object because the specified class is not available in the system. This can occur for several reasons, including missing or incorrectly configured components, or issues with the class definition itself.
  Causes:
  
  Missing Class: The specified class (&1) is not available in the system. This could be due to it not being installed, or it may have been deleted or not properly activated.
  Incorrect Configuration: The configuration for the plug-in may be incorrect, leading to the system being unable to locate the class.
  Transport Issues: If the class was recently transported from another system, there may have been issues during the transport process that prevented it from being properly imported.
  Authorization Issues: The user may not have the necessary authorizations to access the class or create the plug-in object.
