SUM Upgrade Error:


During the upgrade we generally get below error in Check phase if we donít have correct Java Instance ID of system:



The central instance ID that would be calculated by the batch config utility is <XYZ>.

The following problem has occurred during step execution:

The detected instance ID <XYZ> and the one calculated from the box number <ABC> do not match. A possible reason for that is that you have changed the box number in the central instance file.


Root Cause:

This error comes if during the system copy/refresh java part was not taken care by standard SAP tool

We fixed java manually from Configtool after system refresh.


Solution :

Please take Java export of source system and again perform Java Import in target system using System copy tool SWPM.
