I installed the IC upgrade on the weekend and never realized until just now that the Integrity Check that runs on schedule every night (Mon - Fri) ran Monday night (Civic Holiday in Ontario - so I didn't even think to check it). Turns out that Adagio Inventory reported "Item History, Application Integrity ... 485 error(s) found... FAILED. Then, Data Repair Phase, Correcting Phase 2 Errors, A total of 5342 history records were removed. HOLY SMOKES!!!

I looked at the specific items. Here are just a few among the 5342 listed:

Orphan item ZZ URC8017 history record(s) 1 have been removed.
Orphan item ZZ VC7500 history record(s) 2 have been removed.
Orphan item ZZ VE640 history record(s) 10 have been removed.
Orphan item ZZ XRS9730 history record(s) 2 have been removed.

It appears they are all item codes that were previously deleted many months or years ago. We didn't notice anything missing today and tonight's Integrity Check ran without errors.

Is this something new in IC? Perhaps it's cleaning out unneccessary information from the data that pertains to Item codes that no longer exist?
