  The SAP error message LTR2_ES_CHECK266 indicates that there is an issue with the configuration of a receiver RFC (Remote Function Call) destination in the context of a process, typically related to the SAP Landscape Transformation (SLT) replication server. The message states that the receiver RFC destination will be changed from one destination (&1) to another (&2).
  Cause:
  This error usually occurs due to one of the following reasons:
  
  
  Configuration Mismatch: The original RFC destination (&1) may not be properly configured or may not be reachable. This could be due to network issues, incorrect credentials, or the destination being inactive.
  
  
  System Changes: Changes in the system landscape, such as changes in the target system or updates to the RFC destination settings, can lead to this error.
  
  
  Authorization Issues: The user credentials associated with the RFC destination may not have the necessary authorizations to access the target system.
  
  
  Technical Settings: The technical settings of the RFC destination may not match the requirements of the SLT configuration.
  
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check RFC Destination Configuration:
  
  Go to transaction SM59 in the SAP GUI.
  Locate the RFC destination (&1) and check its configuration.
  Ensure that the connection type, target host, and system number are correctly set.
  
  
  
  Test the Connection:
  
  In transaction SM59, select the RFC destination and use the "Connection Test" option to verify if the destination is reachable.
  
  
  
  Review Authorizations:
  
  Ensure that the user credentials used in the RFC destination have the necessary authorizations to access the target system.
  
  
  
  Check for Changes:
  
  If there have been recent changes in the system landscape, verify that the RFC destination settings are updated accordingly.
  
  
  
  Update SLT Configuration:
  
  If the RFC destination needs to be changed to a new one (&2), ensure that the new destination is correctly configured and reachable.
  Update the SLT configuration to reflect the new RFC destination if necessary.
  
  
  
  Consult Logs:
