Hi Jacques
Thanks for the recommendation! Although Eric - the simple answer to your
question is 'No. Creating a requirement doesnt mean that a purchase invoice
automatically is made to a supplier.'
A requirement is used as an indication that you need to order something from
a supplier.
You will still need some type of manual intervention to create the purchase
order. In the case of requirement you can convert it into a purchase order
using the Quick Purchase Order Entry.
When you receive the goods from your supplier and receive them into OFBiz,
this is generally when the purchase invoice is generated.
I hope this helps.
Thanks
Sharan
