DistinctCount Within Table

[ReadTheIron]

I have a table that looks like this:

Asset	IncidentCode	Comments
Switch1	001	Broken
Switch1	001	Fixed
Switch1	002	Who knows?
Switch2	003	Broken
Switch2	004	Broken
Switch2	004	Delayed
Switch3	005	Delayed

I'm trying to create a table visual with a column to indicate how many distinct IncidentCodes each Asset has, which would look like this:

Asset	TotalIncidents	IncidentCode	Comments
Switch1	2	001	Broken
Switch1	2	001	Fixed
Switch1	2	002	Who knows?
Switch2	3	003	Broken
Switch2	3	004	Broken
Switch2	3	005	Delayed
Switch3	1	006	Delayed

Of course if I add a column with a count of the IncidentCode, I get "1" for each row.

Is there something simple I'm missing?

If you add the column again and make it do a Distinct Count, it'll use the context of the table. Try the following measure:

TotalIncidents = CALCULATE(DISTINCTCOUNT(Tabel[IncidentCode]), ALLEXCEPT(Tabel,Tabel[Asset]))

This should ignore filter context and return the desired result.

Hey @ReadTheIron ,

Are you looking for something like this:

Column = CALCULATE(DISTINCTCOUNT(AssetTable[IncidentCode]),ALLEXCEPT(AssetTable,AssetTable[Asset]))

This works well - except that it breaks the filter I'm using to get the table in the first place. My data actually looks like this:

FullTable

Asset	IncidentCode	Comments
Switch1	001	Broken
Switch1	001	Fixed
Switch1	002	Who knows?
Switch2	003	Broken
Switch2	004	Broken
Switch2	004	Delayed
Switch3	005	Delayed
Joint1	006	Stuck
Joint2	007	Stuck
Joint2	007	Fixed

I have another table, related one-to-many on Asset

SwitchTable

Asset

Switch1

Switch2

Switch3

I'd been filtering the FullTable visual by SwitchTable [is not blank]. When I applied the measure as written, I got all of the FullTable Assets. I tried modifying it as below, but got the one-per-row problem again.

StableIncidentsMeasure = CALCULATE(DISTINCTCOUNT(FullTable[IncidentCode]),ALLEXCEPT(SwitchTable,SwitchTable[Asset]))

Hi @ReadTheIron 

Try this measure: 

StableIncidentsMeasure = CALCULATE(DISTINCTCOUNT(FullTable[IncidentCode]), ALLEXCEPT(FullTable,Fulltable[Asset]), ALLNOBLANKROW(SwitchTable[Asset]))

Thanks! Now I'm being asked for further filtering of the data, so I think that I'm just going to give them a matrix and call it a day, but I really appreciate the help!
