Group Orders by Quantity of Item ordered

[WCONGRAVE]

HI

I have a Star Schema Model, with all of the data held in the fact table linked to dimension tables such as customer, calendar, product etc.

Now I have a requirement to report based upon how many items are in an order as per below

Items in Order	Count of Orders	Total £
1	1000	£10000
2	12000	£260000
3	14000	£450000
4	15000	£666000
5	13000	£845000

In my mind, to do this I'd need a Sales Header table with the count of lines in it per order to act as a DIM table. I could then join on the transaction ID and  produce the above report. But my fact table has tens of millions of rows, so calculating this table would take a long time, and the join would be really inefficient. Is there a better way of acheiving this same result in a DAX calculation?

@WCONGRAVE , usually we merge and create single table for sales header and sales transactions

we can count distinct for sales header

or measure like

sumx(summarize(sales, sales[header id], sales[header amount]), [header amount] )
