  The SAP error message BRF390: Function module &1 not found typically indicates that the Business Rule Framework (BRF) is trying to call a function module that does not exist in the system. This can occur for several reasons, including:
  Causes:
  
  Missing Function Module: The function module specified in the error message has not been created or has been deleted.
  Incorrect Configuration: The BRF configuration may be pointing to a function module that is not correctly defined or has been renamed.
  Transport Issues: If the function module was recently transported from another system, it may not have been transported correctly or may not exist in the target system.
  Authorization Issues: The user executing the BRF rule may not have the necessary authorizations to access the function module.
  Namespace Issues: The function module may exist in a different namespace that is not accessible from the current context.
  
  Solutions:
  
  
  Check Function Module Existence:
  
  Use transaction code SE37 to check if the function module exists in the system. If it does not exist, you may need to create it or transport it from another system.

  Authorization Check:
  
  Ensure that the user has the necessary authorizations to execute the function module. You can check this using transaction SU53 after the error occurs.

  Debugging:
