You can enter a comment for each part and tab. Under the Purchase tab you can enter a comment referring to purchase of the part in question. That comment can either be an internal comment or a text that will be printed on the purchase order as text rows each time the part is registered on a purchase order row.
By using the setting Show part's purchase comment on orders/inquiries?, under Orders / Inquiries under the Purchase tab in the Settings procedure, you can choose to include the part's purchase comment in the order rows. By using the Document Viewer button, next to the Comment button, you can create links to other documents that have been created for this part, such as agreements, price negotiations, etc. You should also read the Entering Comments or Instructions section in the chapter called MONITOR General Information in the MONITOR Basics guide to better understand this window.
