Hi;
This module can fulfill your need product_historical_pricet.
Change after comments
As i told youi n my last comment, there is something wrong with the access rights in this module, and now i can confirm it.
This imply some changes in two files:
First file - /security/group.xml
<?xml version="1.0" encoding="utf-8"?>
<openerp>
<data noupdate="1">
<record id="product_historical_user" model="res.groups">
<field name="name">Product Historical User</field>
</record>
<record id="product_historical_manager" model="res.groups">
<field name="name">Product Historical Manager</field>
</record>
</data>
</openerp>
Second file - __openerp__.py
Lines to be changed:
"update_xml" : ["security/groups.xml",
"security/ir.model.access.csv",
"view/product_view.xml",
"data/product_data.xml",
After those changes update your module, and go under Settings ----> Users ---> Users , edit the user you want, and under
Access Rights Tab you will see two new fields "Product Historical Manager " and "Product Historical User ".
It works for me.
Can you test and confirm if this works for you?
