Many users require a detailed description to go with each product.
A typical Quotation would contain the following sections:
Part Number : Product Name : Description : Price (Then, Quantity and Extended or Total Price)
It would be useful to have a "memo-type" field available within the products area so that more detailed product descriptions can be added to opportunities and then to quotes/invoices. (The current Product Name field is limited to 450 characters).
Although you can add a custom memo field to the product area it is not linked to the Part number so cannot be pre-populated with the desired description.
