When viewing a VENDOR in the CRM, the right-hand side displays some useful info about that vendor.

One of them is Open Purchase Orders.

What are the criteria for this?

Some of the "open purchase orders" that are displayed are not open at all- they were delivered and the purchase order is finished. 

How can change this?

Does the "Open Purchase Orders" depend on the Purchase Order drop-down status field (in the individual purchase order).

My fields are as follows:

- Created

- Approved

- Delivered 

- Cancelled

(I cannot remember if these are standard fields, or custom fields that I made)

Thanks in advance,

James
