Hi,

The details operation page get visible based on some condition. The page is defined in the code as follows,

<page string="Detailed Operations" attrs="{'invisible': ['|', ('show_operations', '=', False), ('show_reserved', '=', False)]}">

The value for the show reserved will be set based on the selected the Operation Type, inside the operation type, we have a field Pre-fill Detailed Operations, tick it and also tick the Show Detailed Operations  in the same form.

Thanks
