I have products with an expiry date. The amount of days are stored in a field (product model).
Is it possible to calculate this amount of days to a field (type of date) without any module changes?
The expiry date has to be shown in a delivery order. I tried several things with ReportDesigner in LibreOffice... something using timedelta-function but that was not working in LibreOffice.
Is there another way? Maybe a solution by using xml?
