Currently if you have "Transaction Date Validation" enabled it applies correctly to SL/PL/ and manual stock adjustments (add or write off) etc.
But the date validation settings do not apply to the Manage Stock Take screen >> Field >> [Current Stocktake Date],
With transaction date validation enabled for calendar based 60 days pre and 60 days post
a user mistakenly entered 01/02/2015 instead of 01/02/2016 as the stock take date and this caused discrepencies and queries when running the retrospetive stock valuation
Although this is the date that decides the posting date for the NL adjustments, I would have thought it should still abide to the system transaction Date Validation Settings,
In this case it was still posted to 2016 as prior year/periods were closed,
