Hi,
I had to port a solution from SSAS multidimensional to PowerBI. Unfortunately, it involves many to many relations and parent-child hierarchies:).
I don't get correct sum for the higher level for a measure (first clumn in example below), which shows only positive amounts.
First column - actually a measure is calculated from second column (also a measure) : IF ([ZnesekIzkazPredznakSum] > 0;[ZnesekIzkazPredznakSum];BLANK())
On the leaf level things are ok, but on the parent level, the negative value is included.
Any ideas?
I can also post the Power BI file.
Cheers, Janez
What you've writen can actually work but as a new COLUMN and if it references the column
New Column (Only > 0) = IF ('Table'[Column] > 0, 'Table '[Column], BLANK() )
To make it work as a MEASURE you need to filter out those numbers from the calculation like this...
SUM Only > 0 MEASURE = CALCULATE ( SUM ( 'Table'[Column] ), FILTER ( 'Table', 'Table'[Column] > 0 ) )
Your measure first performs the sum and then looks at the context!
That's why it works only on the lowest level!
When it moves to the higher level - first it sums all the numbers at that level - and then checks if >0
Hope this helps!
Thanks for reply, I'm new to tabular and DAX,please bear with me 🙂
In my case I have added a series of measures, because ob M2M relationship and attributes in the intermediate table which affect calculation in fact table. So I came to final calculation by steps. But only at the final step I want to check for negative amounts. Using your proposed solution would filter underlying negative rows ...
I tried to convert this last measure (before checking for negative) to column, but I get an out of memory error.
