Products Required Missing!
The error message means that the Service Resource whom is assigned to the Work Order does not have the Products which are Required. Not that there are no products required.
You need to create a 'Location', add products to this location, and then assign this Location to the Service Resource. If you add a large quantity of this product e.g. 1000 then you will not see the error message. Set up here:
