Hi,
I have a table visual where each columns have some data and I have created measures to give me the output for each of these columns as 1 and 0 based on each columns criteria.
so for example I have 10 columns , I created 10 measures , each measures has a criteria formula for each of these columns which returns 1's and 0'. below is the 1 measure.
i created other 10 measures to count the occurence of 1's. something like this
Solved! Go to Solution.
So the problem with measures that use patterns like IF( <condition>, 1, 0 ) is that they effectively generate a lot of data that does not exist in your data source. If you have sales data and you table a table with Customer, Product and Date you are forcing the engine to calculate a value for every product for every customer on every day.
Since you are only interested in the 1's changing this to IF( <condition>, 1, BLANK() ) should dramatically increase your performance as the tabular engine is very good at skipping blanks.
But possibly an even faster approach is to just do a countrows of your filter condition which will avoid the IF logic entirely
So you cannot divide the FILTER() function (which returns a table with multiple rows and columns) by a count rows. You should not need to change the [% of width] measure at all - the old measure that references [Value of Highlight W] should still work.
Or you could simplify it and reduce it down to the following (note I recommend getting in the habit of using the DIVIDE() function instead of the numeric / operator as it safely handles divide by 0 or divide by blank)
% of width = DIVIDE( [Value of Highlight W] , Countrows( All(zcvrMaterial) ) )

Thanks @d_gosbell ,
It now works a little faster compare to previous.
However, I also have a measure which calculates the % of occurence of 1's
I have used this measure base on my previous measure.

Thanks @d_gosbell ,
This has now solved my problem.
I did get the infinite output as my value was getting divide by blank.
I have now used the divide function.
Thanks for all your help!
