  The SAP error message 56_CORE773 indicates that there is an issue with the Application Link Enabling (ALE) configuration, specifically related to the receiver determination process. This error typically occurs when the system is unable to find a suitable RFC (Remote Function Call) destination for the specified receiver in the ALE configuration.
  Cause:
  The error can be caused by several factors, including:
  
  Missing RFC Destination: The RFC destination for the target system is not defined in the SAP system.
  Incorrect Configuration: The ALE configuration may not be set up correctly, leading to the inability to determine the receiver.
  Logical System Not Defined: The logical system for the sender or receiver may not be defined or may not match the expected configuration.
  Authorization Issues: The user may not have the necessary authorizations to access the RFC destination.
  Network Issues: There may be network connectivity issues preventing the system from reaching the target system.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Check RFC Destination:

  Ensure that both the sender and receiver logical systems are correctly defined and that they match the configuration in the ALE settings.
  
  
  
  Review ALE Configuration:
  
  In transaction SALE, review the distribution model and ensure that the message type and the corresponding receiver are correctly configured.
