## calculate the diffrence

hi all,
please, i have a measure to calculate the diffrence between the Sales and Target (Diff = Sales - Target), when i visualize this in a Table by Client, so i have positive and negative results (it depends on Sales by Client),

i would like to calculate the Sum of Diff only for the negatives results.

thank you so much

Hi @Sofinobi ,

Using below to simulate your use case. This will give you sum of negative numbers, you need to replace summarize with your visual level filters if any or otherwise with table column that you want to group by(Example difference for products here).

Replace it with your measure that returns the difference.([MQuantity]- [MCustomQuantity] )

MDiff =
SUMX(
SUMMARIZE(DimProduct, DimProduct[EnglishProductName]),
VAR Diff = [MQuantity]- [MCustomQuantity]
RETURN
IF(Diff < 0, Diff, 0)
)

Hi @Sofinobi ,

Hope all is going well.

From your description, you want to create a new measure in Power BI that will sum only the negative differences between Sales and Target for each client.

1. First, here is my sample data.

2. Create a measure value. The specific syntax is as follows.

``````Diff =
VAR a = MAX([Sales])-MAX([Target])
RETURN
IF(a < 0, a, 0)``````

The visual object presented at this time is as follows.

3. If you want to display only negative numbers in the visual, you can format it in Filter as follows.

The visual objects at this time are as follows.

Your needs should now be met. If you encounter any problems, please feel free to contact me. Thank you for your patience and cooperation.

Warm Regards,

@Sofinobi This looks like a measure aggregation problem. See my blog article about that here: https://community.powerbi.com/t5/Community-Blog/Design-Pattern-Groups-and-Super-Groups/ba-p/138149

The pattern is:
MinScoreMeasure = MINX ( SUMMARIZE ( Table, Table[Group] , "Measure",[YourMeasure] ), [Measure])
MaxScoreMeasure = MAXX ( SUMMARIZE ( Table, Table[Group] , "Measure",[YourMeasure] ), [Measure])
AvgScoreMeasure = AVERAGEX ( SUMMARIZE ( Table, Table[Group] , "Measure",[YourMeasure] ), [Measure])
etc.
