How To Fix CNV_CDMC_UCIA025 - Reference and analysis systems are same

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_CDMC_UCIA - CDMC Upgrade/Change Impact Analysis

• Message number: 025

• Message text: Reference and analysis systems are same

What causes this issue?

In the landscape for the current UCIA project, the RFC destinations for
the analysis system and the reference system point to the same SAP
system.
In general, the analysis system is the one that is yet to be upgraded,
while the reference system is the one that has been upgraded. Thus, it
is possible to determine the changes to the SAP objects by comparing
the versions of these objects in the two systems.
If both the roles are assigned to the same system, the comparison
cannot take place because the relevant SAP objects are available in
only one version.

System Response

• What is the cause and solution for SAP error message CNV_CDMC_UCIA025 - Reference and analysis systems are same ?

  The SAP error message CNV_CDMC_UCIA025 indicates that there is an issue with the reference and analysis systems being the same in the context of a data migration or conversion process. This error typically arises during the use of the SAP Conversion and Migration tools, particularly when working with the SAP S/4HANA Migration Cockpit or similar tools.
  Cause:
  The error occurs because the system expects the reference system (the system from which data is being copied or migrated) and the analysis system (the system where the data is being analyzed or processed) to be different.

  Review Migration Scenarios: If you are using predefined migration scenarios, ensure that they are set up correctly and that they do not inadvertently point to the same system.
  
  
  Consult Documentation: Refer to the official SAP documentation for the specific migration tool you are using. There may be additional configuration steps or prerequisites that need to be addressed.
