You use this module if you wish to give notification of requirements of
materials and/or external services and keep track of such requirements.

Requests can be created either directly or indirectly. "Directly" means
that someone from the requesting department enters a purchase request
manually.

The person creating the request determines what and how much to order,
and the requested date.

"Indirectly" means that the purchase request initiated by the
application automatically, for example, from procurement orders (MO,
SO).

A purchase request is an instruction to Purchasing to procure a certain
quantity of materials services, so that they are available at a certain
point in time.

A line of a request contains the quantity and requested date of the
material to be supplied or the quantity of the service to be performed.
You can indicate the service specifications if needed.

Once request is approved go to the Purchase Request Lines from the menu
entry 'Purchase Requests', and also from the 'Purchase' menu.

Select the lines that you wish to initiate the RFQ for, then go to
'More' and press 'Create RFQ'.

You can choose to select an existing RFQ or create a new one. In the
later, you have to choose a supplier.

In case that you chose to select an existing RFQ, the application will
search for existing lines matching the request line, and will add the
extra quantity to them, recalculating the minimum order quantity, if it
exists for the supplier of that RFQ.

In case that you create a new RFQ, the request lines will also be
consolidated into as few as possible lines in the RFQ.
