count occurence of column value in DAX

Hi All,

I have below dataset which contains String as chain of activities. I can have many actvities in real scenarios. Requirements is that I want to give four filters as Activity 1, Activity 2 (eg. with value A,B & C as per the data) and Occurence 1 & Occurence 2 (eg. 1,2,3,4.. up to 10). For example if I select data from four filters as highlighted in screenshot in yellow, Activity 1 ="A" & Occurence 1 ="3" is satiesfied by ID 1 & 2 as "A" is appeared 3 times in the String. Similarly other condition Activity 2 ="B" & Occurence 2 ="2" is satisfied by the ID 1 & 2. So both the condition is met by ID 1 & 2 which should be presented in the table output and count.

Note: There will be many activities in the filter, so user can select any combination of activities and corresponding occurence.

Hope the requirement is clear.

You will want to rethink the UX as you would need to train your users not to specify conflicting filters.

lbendlin Could you explain how this DAX measure works?

Line 2 - bring the data into a usable format. In DAX pretty much the only usable way is to use PATH functions so you replace whatever delimiter you have with a pipe.

Line 3 - materialize the elements of the list (ie the items of the path) into a table

Line 4 - group the table by the elements and add a occurrence count for each

Line 5 - compare the table with the filter settings. Both filters need to match so we only return success if the sum of these two tests is 2.

rob_vander2 try below

Use conditional measure for table visual

Conditional = if( (LEN(max('Table'[String])) - LEN(SUBSTITUTE(max('Table'[String]), SELECTEDVALUE(Filter1[Activity1]), ""))) = SELECTEDVALUE(Filter3[Occurrence1]) && (LEN(max('Table'[String])) - LEN(SUBSTITUTE(max('Table'[String]), SELECTEDVALUE(Filter2[Activity2]), ""))) = SELECTEDVALUE(Filter4[Occurrence2]),1,BLANK())

Use count measure to count the ID

count = CALCULATE( COUNT('Table'[ID]), (LEN('Table'[String]) - LEN(SUBSTITUTE('Table'[String], SELECTEDVALUE(Filter1[Activity1]), ""))) = SELECTEDVALUE(Filter3[Occurrence1]), (LEN('Table'[String]) - LEN(SUBSTITUTE('Table'[String], SELECTEDVALUE(Filter2[Activity2]), ""))) = SELECTEDVALUE(Filter4[Occurrence2]) )
