Hi ahmedrabie,

(Applicable For all user Group)

if you do not want create button in tree view, You can try by giving "create"="false" in tree view

example: <tree create="false">

                   </tree>

If You Want to restrict base on user group then,

you can give only read permission for the perticular Object, for specified group in "ir.model.access.csv" file, or

Settings->Groups->(group_name)->Access rights

Hi Ahmedrabie,

If you want to remove the create button for a particular user, remove the create access rights of that particular class object.

If you want to remove create button completely for that particular screen, add the following in the tree view

<tree string="Sample" create="false">
