Checkinstall error while beginning upgrade to Clarity PPM 15.5

Issue/Introduction

We are current on Clarity 15.4.0 and beginning our upgrade to 15.5. When initiating the upgrade the checkinstall fails with the error:
Load Data Warehouse job has failed last time it was run. Make sure to run it successfully before proceeding the upgrade.
I have run the Load DWH job and it has completed successfully. Still the checkinstall error wouldn't go and it blocks the upgrade.

Environment

Clarity PPM APPLICATION

Resolution

The checkinstall query was picking up an old failed instance of the Load Datawarehouse job as the latest run instead of today’s successful run. After deleted the old entry from job log and the checkinstall identified it as success and upgrade started.
