Subtraction Iteration + Multiplication in DAX

[Anonymous]

Hello

I'm facing a very newbie problem

I have this table:

Selling_Price	ITEM_COST_INCL_VAT	QUANTITY_ORDERED
16.89999962	16.9	930
16.95000076	16.9	200
7.5	7	1200
12	12.84	580
16.95000076	16.9	870
27	26.52	190
17.65999985	16.9	1420
7.5	7	1860
6.800000191	7	1360
7.190000057	7	1860
6.449999809	7	1540
7.5	7	1860
7.449999809	7	820
Total: 157.85	Total: 155.96	Total: 14690

I'm doing this to subtract the Selling Price - Cost Price * Quantity Ordered for each row, but instead, my measure is summing everything..

Forecasted margin (selling price incl VAT - cost incl VAT) = 
VAR selling_price = SUMX(f,RELATED(dCatalog[selling_price]))
VAR cost_price_incl_vat = SUMX(f,[ITEM_COST_INCL_VAT])
VAR quantity_ordered = SUMX(f,[QUANTITY_ORDERED])
VAR margin_per_product = selling_price - cost_price_incl_vat
VAR result = margin_per_product * quantity_ordered
RETURN
result

Result that is showing my measure: 27764

Expected Result: 2800.10

How can I fix that?

Thanks

Diego

@Anonymous Well, you could make your life easy and just do this in a calculated column, 

( [selling_price] - [ITEM_COST_INCL_VAT] ) * [QUANITY_ORDERED]

However, I expect that you don't just have that one table in your model but multiple tables. If that is indeed the case, then, Sorry, having trouble following, can you post sample data as text and expected output?
Not really enough information to go on, please first check if your issue is a common issue listed here: https://community.powerbi.com/t5/Community-Blog/Before-You-Post-Read-This/ba-p/1116882

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.
