Purchase Partner Selectable Option

This module gives you a simple way to keep unwanted contacts out of the vendor selection on purchase orders.

• On the contact form, in the Purchase section, a new checkbox "Selectable in orders" appears. It is stored on the contact and is enabled by default.
• On purchase order forms, the partner field is automatically filtered so that only contacts with this checkbox enabled can be selected. Contacts without the flag no longer show up in the vendor drop-down.
• On the contact form, the smart button that shows the related purchase orders is hidden for contacts that are not selectable in purchase orders.
• A system parameter controls the default value of the checkbox for new contacts. Its default value is "1", meaning new contacts are selectable unless you change the parameter to "0".

The module touches res.partner (the contact model) and purchase.order (the purchase order model). It does not add new menus; the checkbox is added to the existing contact form and the filter is applied to the existing purchase order form.
