From the Contact or Account record navigate to Orders.
The Order form will open. Fill out all fields marked with a red asterisk (except Order ID): Name, Customer, Price List and Currency and click Save.
Order ID is a read only field and will be auto populated after the record is saved. Customer, Price List and Currency should also be auto populated when creating an order from a Contact record.
In the left navigation pane click Products.
In the ribbon bar click Add New Order Product.
The Order Product form will open. Order Products can either be existing Products from the Product Catalog meaning they already exist within the system, or one time Ad-hoc Write In Products. There is a radio button to select one option or the other. All fields marked with a red asterisk are required. When finished, click Save & Close.
The Order Product has now been added to the Order. If you reload the Order, it should appear as part.
