How to config product as make to stock to generate purchase order for zero stocks items?
We are testing odoo 9. Please help how we can configure the products as make to stock? We have products with bill of materials. Their raw materials inventory shall depend on real available quantity. Then when raw materials are zero stock, it needs to generate automatic purchase order upon sales order or manufacturing order confirmation.
My raw materials has 2 to 3 suppliers each for options. What product configuration do i need to automatically generate P.O. For zero stocks? Or do i need to change anything in my current config?
for the raw materials, we use this config: > can be purchased and can be sold > stockable product > others are with 'manufacture' > others are with 'buy'
but none creates automatic PO. I am hesitant to use 'make to order' because it will disregard whether item has stocks, i need it to use existing stocks and only generate PO if without stocks already.
Pls pls help. thanks.
