3361242 - Why the values of the Business Key Fields are different between Source and Target instance after using IST successfully

The values of the Business Key Fields are different between Source and Target instance after using IST successfully.

SAP SuccessFactors HXM Core

1. IST (Instance Synchronization Tool) executed successfully

2. The values of the Business Key Fields in MDF objects are different between Source and Target instance

It is an expected behavior because IST has no impact with the business keys. Business keys will behave as like before.
