MRP Production Serial Matrix

When a manufacturing order produces a product tracked by serial numbers, a "Serial Numbers Matrix" button appears on the MO form (once it is confirmed). It opens a dedicated screen where you pick the finished product serial numbers and fill a grid: each row is a finished serial number, each column a tracked component, and each cell the component lot/serial number consumed.

• The grid is built automatically from the MO's components; serial-tracked components always appear, and lot-tracked ones can be added with the "Include Lots?" option.
• Only lots/serials available in the source location can be chosen, and warnings appear if a serial is used twice, if a lot is not available in the needed quantity, or if some cells are left empty.
• "Validate" processes the MO: it sets the finished serial number, reserves and consumes exactly the selected lots/serials, and handles backorders and chained MOs one serial at a time.
• The matrix has its own status (Draft, In Progress, Exception, Done, Cancelled), can be reset to Draft after an exception, and can only be cancelled by a manufacturing manager once the MO is done or cancelled.
• A list view and a menu "Manufacturing Orders Serial Matrix" under Manufacturing let you find and follow all matrices.
