Hi,
While installing this https://apps.odoo.com/apps/modules/11.0/mro/ application on Odoo 11, I am getting the following error
TypeError: Model 'mro.order' inherits from non-existing model 'ir.needaction_mixin'.
Can someone guide?
I have checked this community http://codup.com/en/applications/maintenance/191-mro.html but no response from them
