Hello all,

After I have made all fields editable in the status ‘posted’ in Accounting(Account.move.line), I would now like to hide the delete icon, the buttons ‘Add a line’, ‘Add a section’ and ‘Add a note’ in the status ‘posted’. 

I used this to make the fields in the TreeView editable:

Override in --> account.move
invoice_line_ids = fields.One2many(  # /!\ invoice_line_ids is just a subset of line_ids.
    'account.move.line',
    'move_id',
    string='Invoice lines',
    copy=False,
    readonly=False,
    domain=[('display_type', 'in', ('product', 'line_section', 'line_note'))],
)

<xpath expr="//field[@name='invoice_line_ids']/tree" position="attributes">
	​<attribute name="create">0</attribute>
   <attribute name="delete">0</attribute> 
</xpath>

With this i hide it for all status.

Many thanks all!
