• What is the cause and solution for SAP error message LTR2_ES_CHECK045 - No RFC destination to sender system ?

  The SAP error message LTR2_ES_CHECK045 indicates that there is no RFC (Remote Function Call) destination configured for the sender system in the context of a landscape transformation or data migration process. This error typically arises when the system is trying to establish a connection to another SAP system but cannot find the necessary configuration to do so.
  Cause:
  
  Missing RFC Destination: The most common cause is that the RFC destination for the sender system has not been created or is incorrectly configured.
  Incorrect Configuration: The RFC destination might exist but could be misconfigured (e.g., wrong system ID, incorrect logon credentials).
  Network Issues: There could be network connectivity issues preventing the systems from communicating.

  Solution:
  
  
  Create or Verify RFC Destination:
  
  Go to transaction SM59 in the SAP GUI.
  Check if the RFC destination for the sender system exists. If it does not, create a new RFC destination.

  Enter the correct details, including the target system's hostname, system number, and logon credentials.
  
  
  
  Test the RFC Connection:
  
  After creating or modifying the RFC destination, use the "Test Connection" feature in SM59 to ensure that the connection is working properly.
  
  
  
  Check Authorizations:
  
  Ensure that the user credentials used in the RFC destination have the necessary authorizations to access the target system.
