DDMRP Product Replace

This module adds a Product Replacement Tool to the DDMRP configuration menu (visible to inventory managers). In the wizard you pick the products to be replaced, the buffers affected are listed automatically, and you choose the substitute product — either an existing one or a brand new product created by copying the old one, optionally copying routes, put-away rules and packaging.

Two replacement modes are offered: create a new buffer for the replacing product, or replace the product directly in the existing buffers. When several products are replaced at once, only the buffers of the primary product are used to create the replacement buffers; the others are linked to them.

On each buffer, a 'Replaced by' link and a 'Replaces' counter are shown, with a red alert banner when a product is being replaced. A button opens the list of buffers replaced by the current one. Buffers can be flagged as replacement products, and you can include the incoming and on-hand quantities of the replaced products in the buffer status calculation, which affects the net flow position. Past demand of replaced products can be considered as demand for the new product.

The module blocks recursive replacement chains, requires the buffered product to be part of its own demand products, and prevents replacing buffers that are already replaced. It also warns users in the procurement request wizard when some products are being replaced, and stops procurement recommendations for buffers that have been replaced.
