Power BI Filter expression using terms from related tables

I have an invoice table and a related Order table and I want to calculate the cumulative invoiced sales as well as the cumulative order intake.  Because the current date is the invoice date, I am trying to sum orders with order date <= invoice date.

I haver a relationship from Order Number in the invoice table to Order Number in the Orders table.

The cumulative invoiced sales works fine...

Sales 01 Cumul = CALCULATE(
 SUM('Invoice_Summary All'[Sales 01]),
 FILTER(
  ALLSELECTED('Invoice_Summary All'),
  'Invoice_Summary All'[To] <= MAX('Invoice_Summary All'[To])
 )
)

But I can't get the order intake to work.  This is what I tried...

Order Intake Cumul = CALCULATE(
 SUM('Invoice_Summary All'[Sales 01]),
    FILTER(
        ALLSELECTED('Order Headers All'),
        'Order Headers All'[Order date] <= MAX('Invoice_Summary All'[To])
    )
)

This tries to run for ages until it fails reporting insufficient memory.
