Purchase Commercial Partner

This module adds a new field called "Commercial Vendor" on purchase orders. It is filled automatically from the vendor selected on the order: if the vendor is a contact belonging to a parent company, the parent company is shown instead. The value is stored in the database, so it can be used for grouping and reporting.

Where it appears: - On the purchase order form, the field is added next to the vendor field but kept hidden; it is used behind the scenes. - In the purchase orders search filters, a new "Commercial Vendor" grouping option is added, so you can group orders by the parent company of the vendor. - In the purchase analysis report, the same "Commercial Vendor" grouping option is added, so you can analyse purchase figures by parent company.

Business behaviour: the value is computed from the vendor's commercial entity and stored, so it stays available for grouping even if the vendor contact changes later. No checks, restrictions, emails or scheduled jobs are added by this module.

It touches the purchase order model (purchase.order) and the purchase analysis report (purchase.report).
