For example,
I have 2 chairs in stock, but the sales order needs 5 chairs.
Once the sales order has been confirmed, a Purchase Order will be auto generated, but the PO will have the enitre qty of 5, despite that I already have 2 in stock.
How do I setup the buying rule so it only buys the shortfall?
And committ both the 2 in stock and 3 on purchase order to the sales order?
Thank you.
