Hello Jean,

Yes, Its possible. You can create a new group or assign an existing group where only project managers are allowed and assign that group to the planned hours field.By doing this the user that doesn't belong to that group will not be able to see that field.

You can create a group in security/security.xml file of the module

<record id="Your_new_group" model="res.groups">
<field name="name">Your new group</field>
<field name="users" eval="IF YOU HAVE USERS CREATED IN DEMO DATA"/>                                    </record>

Note: you can also later assign users to this group from interface

Then go to the form view of project task and apply this group to the fields that you want to restrict. for eg:<field name="planned_hours" groups="project.Your_new_group"/>

Through Interface:

Referring 7.0 there is already a group available for this field. Just go to Settings/Users/Users

Edit the user that you want to apply restriction on. Go to second Tab (Access Rights) You will see under Technical Settings a boolean entry as 'Time Estimation on Tasks' just untick that for the user.

Note: If you are not able to view Technical Settings then you need to check the boolean Technical Features under the Access rights tab for the logged in user only then you will be able to view the details settings.

Thanks,

Creating group same not object level or field level, but how to use this field is depend you.

You can create group as usual in folder security --> security.xml file.

<record id="group_new" model="res.groups">
    <field name="name">new group</field>
    <field name="category_id" ref="base.module_category_hidden"/>
</record>

Hi, here the solution I put in place. Comments welcome if you saw some basics problems.

• Activate debug mode
• Go to the task view
• In the debug dropdown select "Edit Formview"
• Copy the the line containing the "planned hours" (see exemple below)
• In one line add the groups attributes with the group allowed to edit (here project manager)
• in other line add the Readonly group and the field attributes readonly="1" (here project user)

<field name="planned_hours" widget="float_time" groups="project.group_project_user" on_change="onchange_planned(planned_hours, effective_hours)" readonly="1"/>

<field name="planned_hours" widget="float_time" groups="project.group_project_manager" on_change="onchange_planned(planned_hours, effective_hours)"/>

Note1 : The technical feature "Task estimation" will be disabled for this specific field. The field will be visible by every users.

Note2 : For Manager the field will be displayed 2 times because of the inheritance from User, to avoid that you should remove the inherice
