Maybe I missing something but on version 4.8 stock_supply_production and stock_supply_purchase do not create requests if stock_lot_sled is installed.
- Create products: Product, Component 1 and Component 2
- Create a Bom:
100 units component 1
200 units component 2 -> 1 unit Product.
- On Production Configuration, set supply period 5d.
- Create a sale: 100 units of Product delivery 3 days later.
- Execute: Inventory & Stock/Order Points/Supply Stock.
If you uninstall stock_lot_sled and restart server and execute:
Inventory & Stock/Order Points/Supply Stock. you get 2 purchase request and one production request.
With stock_lot_sled installed, if you change planned_date field from customer shipment to today, purchase and production requests are created.
