  Cause:
  
  Invalid Function Module: The function module referenced in the error message (&1) is either not defined, has been deleted, or is not active in the system.
  Configuration Issues: There may be configuration issues in the B2B settings or in the CPM settings that are causing the system to reference an invalid function module.

  Check Function Module:

  Transport Management:

  If necessary, re-transport the missing function module or related objects.
  
  
  
  Authorization Check:
