When WIP is posted in a new period, the WIP from the previous period is reversed and the new WIP is posted, both with the new posting date.
By posting both the reversal and the new WIP on the new posting date, the WIP remains in the previous period.

But what if you find out that the WIP in an even earlier period is wrong?
You would want to undo all WIP postings back until that earlier period and recalculate in all periods.
This is however not possible using the standard 'Post WIP to G/L' report, not even by using the "Reverse only" tick.

I would be nice if the report could also be used to reverse all WIP postings in a specified period (back until that period).
