[pedrobaeza]

No grouping on procurement purchases

This module allows to not group generated purchase orders from procurements. The grouping behaviour can be configurable at product category level.

Configuration

Go to each product category, and select one of these values in the field "Procured purchase grouping":

• Standard grouping (default): With this option, procurements will generate purchase orders as always, grouping lines and orders when possible.
• No line grouping: With this value, if there are any open purchase order for the same supplier, it will be reused, but lines won't be merged.
• No order grouping: This option will prevent any kind of grouping.

It comes from odoomrp-wip project.
