Hi,
I spend a lot of time trying to find a solution.
The solution found on internet does not work : CALCULATE([Total Sales],SAMEPERIODLASTYEAR('Date'[Date]))
I have one table (INVOICES) with the following informations :
- INVOICE NUMBER
- ORDER NUMBER
- INVOICE DATE
- CUSTOMER
- SUPPLIER
- CATEGORY
- PRODUCT EAN
- PRODUCT PRICE
- MARGIN
- QUANTITY
So I added a column to calculate the total amount of each line of the invoice (called TOTAL), and the amount of the total of each margin (TOTAL MARGIN)
For one INVOICE NUMBER, I may have thousands of lines, but only one ORDER NUMBER
For one ORDER NUMBER, I may have severel INVOICE NUMBER.
I also have a date table.
With this solution, I can know the SALES, MARGIN by CATEGORY, SUPPLIERS and CUSTOMERS, by date, etc... this is working well (it is quite simple)
What I need is a comparison between this year and last year.
So I tried the solution above with a calculated column, but it is not working. It is empty.
So I tried to create to a new table (SUBTOTAL), that summarize, by DATE, SUPPLIERS, CATEGORY and CUSTOMERS (so without the details by PRODUCT EAN) the buy amount, sales amount and margin amount.
This is working well
Then I added a new column with the formula :
SALES LY = CALCULATE(sum('SUBTOTAL'[SALES TOTAL]);SAMEPERIODLASTYEAR('date'[date]))
It is still empty
What am I missing ?
Thanks for your help
Regards
