Hi,
I am trying to work out what total purchasing costs will be depending on which supplier I purchase from. This means that the purchase price isn't in the fact table like it would normally be in a calculated column. There is a different product price for each supplier.
So the tables I have are:
- a product table with each product in once, with columns for product category and size
- a price table linked to the product table with the price of each product for each supplier
- a purchase table linked to the product table for how much I need to purchase of each product
I'm wanting to do a row by row calculation as if it were a calculated column but in a measure, with the calculation being:
supplier's product price * quantity
Does anyone have any tips on how they have dealt with this issue before?
Many thanks,
Paddy

Hi,
Share some data and show the expected result.
@Anonymous - Quick Question - How would you decide the price when each supplier can have a different price for the product. So when you say
Cost = Qty * Price (which price is it?)
Unless you have the bifocation of purhcase quantity by supplier, there is ambiguity in solving this problem.
Hi @Ashish_Mathur @ChandeepChhabra
Many thanks for your replies. I am trying to see which supplier I should source certain groups of bottles of sauce from. The product groups are 'size' and 'recipe', so I want to see the impact of sourcing either a whole size of bottle from each supplier.
Fact table:
Product | Purchase Quantity |
1 | 100 |
2 | 50 |
3 | 200 |
4 | 300 |
5 | 500 |
6 | 200 |
7 | 20 |
Product Table:
Product | Size | Recipe |
1 | 125g | Lemon |
2 | 125g | Sweet |
3 | 125g | Hot |
4 | 250g | Lemon |
5 | 250g | Sweet |
6 | 250g | Hot |
7 | 500g | Lemon |
Product Prices table:
Product | Supplier | Price |
1 | SUP1 | £5.10 |
1 | SUP2 | £5.50 |
1 | SUP3 | £4.20 |
2 | SUP1 | £4.90 |
2 | SUP2 | £4.50 |
2 | SUP3 | £5.60 |
3 | SUP1 | £3.60 |
3 | SUP2 | £3.20 |
3 | SUP3 | £5.00 |
4 | SUP1 | £6.00 |
4 | SUP2 | £5.30 |
4 | SUP3 | £5.20 |
5 | SUP1 | £6.50 |
5 | SUP2 | £5.70 |
5 | SUP3 | £5.00 |
6 | SUP1 | £4.90 |
6 | SUP2 | £5.20 |
6 | SUP3 | £4.30 |
7 | SUP1 | £7.50 |
7 | SUP2 | £7.20 |
7 | SUP3 | £8.40 |
Then it would come to the pivot for the results by supplier and receipe/size
SUP1 | SUP2 | SUP3 | ||||
Total Qauntity | Total Cost | Total Qauntity | Total Cost | Total Qauntity | Total Cost | |
Hot | 400 | £1,700.00 | 400 | £1,680.00 | 400 | £1,860.00 |
Lemon | 420 | £2,460.00 | 420 | £2,284.00 | 420 | £2,148.00 |
Sweet | 550 | £3,495.00 | 550 | £3,075.00 | 550 | £2,780.00 |
It is possible to merge the price and fact tables so that I have a calculated column like below, but this wouldn't be the best solution long term as I might add other elements to the data model such as calendar, and I would keep needing to merge tables together.
Product | Size | Product | Size | Recipe | Supplier | Price | Quantity | Total Cost |
1 | 125g | 1 | 125g | Lemon | SUP1 | £5.10 | 100 | £510.00 |
1 | 125g | 1 | 125g | Lemon | SUP2 | £5.50 | 100 | £550.00 |
1 | 125g | 1 | 125g | Lemon | SUP3 | £4.20 | 100 | £420.00 |
Any help would be much appreciated. Many thanks, Paddy
