SQL CASE to DAX

[kevinsray]

I have been trying to convert this SQL case to Dax to work in Power Bi, but just can`t seem to find the right formula.
SELECT TOP(100) STOCKCODE, SUM(QUANTITY) as 'QUANTITY'
FROM (SELECT DI.STOCKCODE,
(CASE WHEN SI.CHKQTY = 'Y' THEN QUANTITY * NITS_PER_CARTON
ELSE QUANTITY
END) AS QUANTITY
FROM DI
JOIN SI
ON SI.STOCKCODE = DI.STOCKCODE

Any hints would be greatly appreciated.

Hi @kevinsray ,

You can create a calculated table Table1 first of all, then add index column in the Table1, and then create measure Sum for Quantity .

Table1 = SELECTCOLUMNS(FILTER(DI,DI[STOCKCODE]=MAX(SI[STOCKCODE])),"STOCKCODE",DI[STOCKCODE],"QUANTITY",IF(MAX(SI[CHKQTY] )= "Y",[QUANTITY] * [NITS_PER_CARTON],[QUANTITY] ))

Sum for Quantity = CALCULATE(SUM(Table1[QUANTITY]),FILTER(Table1,Table1[Index]<=100))

Amy,

Thank you for your help.

I am using the formula to create the table, but one small issue.

This QUANTITY * NITS_PER_CARTON calculation is actually from 2 different tables.

So, I guess I should have written DI.QUANTITY * SI.NITS_PER_CARTON

Is there any way to get around this?
