How to check if sales contain certain products?

[BorisTPL]

Hi, I'm trying to create a calculated column or measure that does the following:
I have two tables, a sale table and a saleline table. The Sale table contains 1 line per sale and only has the salevalue, but no product info. The Saleline table contains a more detailed overview and has more lines per sale when more than 1 product is purchased.

For example,

Sale table looks something like:

And for the same sale the Saleline table looks like this:

We are a phone repairshop. Now I want to measure how many sales contain a screen replacement ánd a screenprotector. The code for a calculated column in the Sale table should check for the same SaleID in the Saleline table and check if this is the case with 3 possible outcomes: 

- No screen repair

- Screen repair without screenprotector

- Screen repair with screenprotector

I can calculate the amount of screenrepairs using measure:

Amount of screen repairs = CALCULATE(SaleLine[Aantal Workorder sales], FILTER('Item','Item'[Type] = "Scherm"))
I can calculate the amount of screen protectors using measure:

Amount of screenproctors = CALCULATE(sum(SaleLine[unitQuantity]),Category[Subcategory1] = "Clearplex", FILTER(SaleLine, SaleLine[calcSubtotal] <> 0 ))

Screenproctors are also sold without a screen repair so just dividing them is not the desired output.

Is there a way to combine the filters in a way for multiple lines? 

Hope you can push me in the right direction. Thanks in advance

@BorisTPL  You can filter the sales table using the measures you've already created: 

Sales Count with Screen Repair & Protector =

CALCULATE( [Total Sales Count]

, FILTER(Sales,

[Sales Count with Screen Protector]>0 && [Sales Count with Screen Repair]>0

)

)
