CKF in BEx Query Designer

Question

Hello,
I have following scenario in Query Designer:
There is only one characteristic Material in row and 3 calculated Key figures in column Price (Current Year), Price (Current Year -1), Price (Current Year -2). The User gives the current year as Input Variable. It works so far fine.
Query Output looks like:
MATERIAL | PRICE (CURENT Y) | PRICE (CURRENT Y-1) | PRICE (CURRENT Y-2)
1234 |10|20|--
2345|10||
3456|12|--|23
4653|12|13|14
7564|--|2|5
6452|||8
7362||7|
You can see that at least one value of PRICE Current Year/Current Year-1/Current Year-2 per Material is always filled. All Prices are in EUR.
Now my requirement is that I have to build a new Calculated Key Figure in Query designer which should calculate the minimum value of PRICE Current Year/Current Year-1/Current Year-2 per Material.
The new Query Output should look like this:
MATERIAL | MINIMUM (PRICE CURRENT Y to CURRENT Y-2)
1234 |10
2345|10
3456|12
4653|12
7564|2
6452|8
7362|7
I have tried to use Mathematic Function MIN but couldnu2019t get success as few cells are empty. So I cannot use function MIN. When I add empty cell with 0 then the minimum value calculates incorrect. It only works when all 3 cells are filled. How I can solve this problem in Query Designer?
Many thanks for the help.

Hi Moha Nan,
Try this:
PRICE CURRENT Y *
((PRICE CURRENT Y NE 0) *
((PRICE CURRENT Y-1 NE 0) * (PRICE CURRENT Y < PRICE CURRENT Y-1) + (PRICE CURRENT Y-1 == 0))
((PRICE CURRENT Y-2 NE 0) * (PRICE CURRENT Y < PRICE CURRENT Y-2) + (PRICE CURRENT Y-2 == 0)))
+
PRICE CURRENT Y-1 *
((PRICE CURRENT Y-1 NE 0) *
((PRICE CURRENT Y NE 0) * (PRICE CURRENT Y-1 < PRICE CURRENT Y) + (PRICE CURRENT Y == 0))
((PRICE CURRENT Y-2 NE 0) * (PRICE CURRENT Y-1 < PRICE CURRENT Y-2) + (PRICE CURRENT Y-2 == 0)))
+
PRICE CURRENT Y-2 *
((PRICE CURRENT Y-2 NE 0) *
((PRICE CURRENT Y-1 NE 0) * (PRICE CURRENT Y-2 < PRICE CURRENT Y-1) + (PRICE CURRENT Y-1 == 0))
((PRICE CURRENT Y NE 0) * (PRICE CURRENT Y-2 < PRICE CURRENT Y) + (PRICE CURRENT Y == 0)))
replace the NE with the not equal to sign, the post forum doesn't seem to accept thos signs.
Kind regards,
Alex
