Finishing of production order - Inventory gen. exit

Hi,

when Im finishing production order, there is journal entry with date which is set on production order as Production order date (field PostDate in OWOR table). This date after creating production order cannot be changed.

The problem is, when the posting period which belongs to production order date is closed, there is no possibility to finish the production order.

Is there any chance to finish production without reopening the posting period?

thanks
