Automatic procurement happens with the correct configuration of Procurement Method and Supply Method and with complete information on minimum stock rules, suppliers, bills of materials, etc.

You have to set the field Procurement Method of the product to Make to Order or setup minimum stock rules for Make to Stock products to get RFQ's (which you can confirm into PO's) created for items with a Supply Method of BUY.

You need to setup a BILL OF MATERIALS for items with a Supply Method of MANUFACTURE to get MO's generated automatically.

Then, you run the Scheduler, or install Just in Time.

If there are any exception in automatic procurement, then you see them in menu "Warehouse / Schedulers / Procurement Exceptions".

Something commonly overlooked is that Items you BUY must have a SUPPLIER with an ADDRESS set or no RFQ will be generated.

I had the problem that my MO we're not created and it was only a configuration problem!

Here's what I did : go in the menu Settings > Configuration> Manufacturing and then in the sub-section Planning, you must have Generate procurement in real time checked! For the next order, it will create your MO with all the rules you've defined.

For the orders that you've already defined but there was no MO associated, go in the menu Warehouse > Schedulers > Procurement Exception. Delete the default filter in the search box and you should be able to see the last order you have created! Go in it and you just have to click Run Procurement and then your MO is created!
