I believe this problem might have an easy solution but I'm not too sure.
I'm wanitng to find the total cost for a product with mutiple ingredients over a selection of past months when prices differ.
I've taken a simplified version of the two tables im using (below) which are connected via Ingredient ID with a many-to-many relationship. (ignore etc.) BOM:
I'm trying to get a total cost for each product, which can vary depending on the month (ive not included date table here). For product 1 in July, I've created this table and would like the Total Product Cost to add up to equal 1.5+425+6+154 = 586.5 but at the moment its giving the multiplied sum of Quantity and Price tables.
The formual I've used for Total Production Cost measure is below, I know it's wrong as I'm using sum on the columns but have no idea what else to use.
Total product cost = CALCULATE(sumx(BOM,BOM[Quantity])*SUMX('Component cost','Component cost'[price]))
What measure should I use to work out this addition? or is this not possible as I'm using a many to many relationship?
