The system sums material specifications of the order items estimated material usage in kg. The material specifications are checked against the free material stock for the date when the material is needed. The material check is done for the plate and profile material when printing the quotation. If there is not enough material, a warning is given, but it does not prevent approving the quotation and making it into a sales order.
Material check is available only if the reservation functionality is enabled, which is enabled by default.
