Qty Adjustments lets you pick a Date and fat fingering the date is quite common. So someone might have added a Qty Adjustment with a date of let’s say 2090. Since the Stock Status Report is an “as-of” report, it will go for many years into the future.
If you go to one of the Part Tran, Transactions, History trackers - don’t set a cut-off date and see if you can find a Transaction way out there, light-years away.
Or create a BAQ and run it
SELECT * FROM Erp.PartTran WHERE TranDate >= '01/01/2020'
