Stock Product Demand Info

This module adds a "Demand by period" indicator that summarises how much of a product has been shipped out over chosen time windows.

Where it appears: - On the product form, in the Inventory section, for storable products only. - On replenishment rules (orderpoints), both in the list and in the form, next to the forecasted quantity. There the figures are limited to the rule's warehouse. - In Inventory settings, where you pick which periods are shown and open a screen to manage them.

How it works: - Demand periods are records with a name, a start and an end date expression (for example "today -30d" or "today =1d -1y"), and a sequence. Several are preloaded (Last 30 days, Last year, Year to date active by default; others inactive). - The system checks that each expression is valid and that the start is not after the end, otherwise it blocks saving with an error. - Quantities are computed from stock moves in confirmed, assigned, partially available or done states, with positive quantity, dated within the period and before today. Only outgoing moves to customers or production count on the product form; on a replenishment rule, moves leaving that warehouse count. - On a product template, the figures are the sum of its variants.

Access: stock users can read periods; only stock managers can create, edit or delete them.
