Odoo sale.layout_category module

Question

I created a test accounting odoo application in http://odoo.com, The odoo version is Odoo 11.0+e (Enterprise Edition).

When creating an invoice line, I should fill the field layout_category_id which is attached to the module sale.layout_category, but I can not find this module.

Can someone help me to activate this module?

Thanks

I fixed the problem by adding 'Sales' plugin to the app.
