Dynamic subtraction based on selection of records

[dam0853]

I'm wondering if this is possible in PowerBI. I've attached a screenshot of the data.

As users multiselect data in a table, can PowerBI dynamically calculate what the score will be. 

For example, if they select the first two items in the list (yellow rows), can PowerBI dynamically calculate that ScoreAfterGroup should be 752?

Thanks,

You can  do this dynamically using a simple Measure that would serve as both your ScoreAfter in an unsummarized Table and your ScoreAfterGroup as a Card with a Sum aggregation.  Measures are great because they respond to your selection, but there are limitations. See Measure below:

ScoreAfter = AVERAGE(Sheet1[Score]) - SUM(Sheet1[Reduce])

Not sure if this is what you are looking for, more information about the "dynamic" selection and whether the groups have a common criteria  unifying them.  You wouldn't be able to display it dynamically as you are showing in your image as far as I am aware.

@dcampbell321 that didn't seem to work. I used to use the FIXED option in Tableau to provide some type of LOD calc for this based on the ID, but I am at a loss in PowerBI

@dam0853 try this, make sure to change table name and column name as per your data model.

Score After = MAX( Table3[Score] ) - SUM( Table3[Reduce] )

@dam0853 so your calulation look like is this

for yellow: 820 - (54+14) = 752

for blue   : 820 - (14+14+12) = 780

Correct?

@parry2k Correct, but I want it to be dynamic, so if I were to select only the first records in the colored sets, it would look like:

820-54(first record from yellow dataset)-14(first record from blue dataset) = 752.

Make sense?

@dam0853 sure the solution provided by @dcampbell321   will work, only issue it will average out the score if selection is made from two different set of scores. Based on your model that is the best option, or you can use MAX instead of AVERAGE
