[FIX] sequence.get is deprecated

[Romain Deheele - Camptocamp (romaindeheele)]

Hello,

I see 3 points:

- integrity error on framework agreement deletion

- import pdb in def open_agreement (maybe voluntary)

- change price in a FA doesn't change price in existing purchase order lines, is it voluntary?

As discussed a better message will be nice but nice to have.
>

Fixed

Yes but we should add a warning on change of price if related to a PO

[MRG] missing domain on supplier field

[Joël Grand-Guillaume @ camptocamp (jgrandguillaume-c2c)]

Hi,

This LGTM. I just have the little remark I already made:

 * Adding a LTA on a product should add a supplierinfo entry as well.

A part from that, LGTM. I don't want to block it for that. Just to let you know.

Regards,

+Long Term Agreement (or Framework Agreement) on price.
+======================================================
+
+Agreements are defined by a product, a date range , a supplier, a price, a lead time
+and agreed quantity.
+
+Agreements are set on a product view or using a menu in the product configuration.
+
+There can be only one agreement for the same supplier and product at the same time, even
+if we may have different prices depending on lead time/qty.
+
+There is an option on company to restrict one agreement per product at same time.
+
+If an agreement is running its price will be automatically used in PO.
+A warning will be raised in case of exhaustion of override of agreement price.
+
+**Technical aspect**
+
+The module provide an observalbe mixin to enable generic on_change management on various model
+related to agreements.
+
+The framework agreement is by default related to purchase order but the addon
+provides a library to integrate it with any other model easily
