MRP Request Workcenter Cycle

This module links products and workcenters so that production quantities can be planned by machine capacity instead of being typed manually.

On a product form you get a new "Capacity by workcenter" table where you list, for each workcenter, how many products it makes in one cycle and how many cycles are normally used. A workcenter can only appear once per product.

On a Manufacturing Request a new "Workcenters" tab appears. When you pick a product, the lines are filled automatically from the product's capacity settings. You can enter a target quantity, and the number of cycles is adjusted proportionally so the total matches your target. The request quantity is then computed automatically from the cycles and products per cycle; if the request unit differs from the product's unit, an error is raised.

A "Create Manufacturing Orders" button is shown once the request is approved and no manufacturing order exists yet. It creates one manufacturing order per cycle: whole cycles produce a full batch, and a remaining fraction produces a partial batch. The workcenter name is added to the manufacturing order origin. The standard create button is hidden when workcenter lines are present, and the quantity field becomes read-only once lines exist or the request leaves draft.
