I just faced a similar problem, may solution was to add a record rule for the Administration / Settings
group, here is how:
1- Go to Settings->Groups
and select Administration / Settings
. (Make sure this group is assigned to de new user)
2- Click the Edit
button and go to the Rules
tab. (It should be empty)
3- Click the Add
button, this action open a modal window, click the Create
button on it.
4- Give the new rule a semantic name - e.g. Partner: administration settings: see all
- and make sure all the access rights are selected.
5- In the object drop down type res.partner
, it will allow you to select the object named Partner
referenced in the error.
6- Click the Add
button in the Groups
section and select the Administration / Settings
group.
7- Finally click the Save & Close
button and save the group changes by clicking the Save
button.
Hope this is helpful for beginners in OpenERP. Actually I already have used this solution patter more than once for similar error related to permissions a given user was expected to have.
