Hi Vivek,
Please check below two notes if not helpful then raise a message to SAP.
NOTE 1632586 - VALIDATE_QUEUE step in SUM fails due to product mismatch
Reset SUM using the Back button on the GUI repeatedly and then exit SUM process.
NOTE: If the Back button is inactive (disabled), this means that a phase is still running and you must proceed as described in "Resetting the Software Update Manager" section in the SUM guide.
If reset is not done properly on a dual-stack system, you will get an error in the ABAP phase "VALCHK_INI" when starting SUM again.
NOTE: 1790486 - SAPup broke during phase VALCHK_INI in module PREP_INIT / Initialization
Resolution
Only perform the following steps if you were in one of the Preparation Roadmap steps (1-4) when you tried to reset the previous upgrade:
- Change to the upgrade directory
UNIX: <upgrade directory>/abap/bin
WINDOWS: <upgrade directory>\abap\bin
- Execute the following command:
UNIX: ./SAPup reset prepare
WINDOWS: .\SAPup.exe reset prepare
- Rename the current upgrade directory
NOTE: Once you have confirmed that the reset was done properly, you can then delete the directory.
- End all the SAPup processes on the operating system (OS) level (if any exist)
- Download the latest SUM patch from Service Marketplace (SMP)
- Start the upgrade from scratch
Thanks
