In our situation, we have to do a Production when an order is completed, in order to reserve the material. Unfortunately, this Production can only be an estimate, since we can't predict whether our shop will use new inventory or scraps. So we imagine that at invoice time (which can be several weeks after the order is completed), we will have to do another Production, with some +plus and some -minus quantities to reflect the actual usage. Is this an appropriate use of the Production feature?
