SAP Error Message - Details

• Message type: E = Error

• Message class: LTR2_ES_CHECK - LTR2 Checks on Embedded Specification

• Message number: 264

• Message text: RFC settings in embedded specification and migration subproject differ

What causes this issue?

The RFC destinations for either the sender system, the receiver system
or both are different between the embedded specifcation and the
migration workbench (MWB) subproject that is assigned to the embedded
specification.
An overview of the all relevant RFC destinations is given in the
following list:
Sender RFC destination in embedded specification: &V1&
Sender RFC destination in MWB subproject: &V2&
Receiver RFC destination in embedded specification: &V3&
Receiver RFC destination in MWB subproject: &V4&

System Response

If you start a migration using MWB, then it is not garantueed that the
data will be read from the correct system or that the data will be
written in to the correct system.

How to fix this error?

Please execute the repair report. This report will adjust the RFC
destinations of the MWB subproject to the ones that are defined in the
embedded specification.

• What is the cause and solution for SAP error message LTR2_ES_CHECK264 - RFC settings in embedded specification and migration subproject differ ?

  The SAP error message LTR2_ES_CHECK264 indicates that there is a discrepancy in the RFC (Remote Function Call) settings between the embedded specification and the migration subproject. This error typically arises during the process of data migration or when configuring the system for embedded analytics or other functionalities that rely on RFC connections.
  Cause:
  The error occurs when the RFC settings (such as destination, user credentials, or connection parameters) in the embedded specification do not match those in the migration subproject. This can happen due to:
  
  Configuration Mismatches: Different RFC destinations or settings have been configured in the embedded specification and the migration subproject.
  System Landscape Changes: Changes in the system landscape, such as updates or migrations, that have not been consistently applied across all components.
  User Authorization Issues: The user credentials or authorizations set in the RFC destination may not be valid or consistent across the different components.
  
  Solution:
  To resolve the LTR2_ES_CHECK264 error, follow these steps:
  
  
  Check RFC Destinations:
  
  Go to transaction SM59 in the SAP GUI.
  Verify the RFC destinations used in both the embedded specification and the migration subproject.
  Ensure that the settings (such as target host, system number, client, user, and password) are consistent.
  
  
  
  Review Configuration:
  
  Check the configuration settings in both the embedded specification and the migration subproject.
  Ensure that any relevant parameters (like connection type, logon data, etc.) are aligned.
  
  
  
  User Authorizations:
  
  Ensure that the user credentials used in the RFC connections have the necessary authorizations to access the required resources in both the embedded specification and the migration subproject.
  
  
  
  Test RFC Connections:
  
  Use the Connection Test feature in transaction SM59 to verify that the RFC connections are working correctly.
  If there are issues, troubleshoot the connection settings or network issues.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific version of SAP you are using, as there may be additional considerations or known issues.
  
  
  
  Reconfigure if Necessary:
  
  If discrepancies are found, reconfigure the settings in either the embedded specification or the migration subproject to ensure they match.
