DAX measure or Summarized table

[reidnmorrison]

Hello, 

I have data in the below format. I want to create a measure that will calculate the number of staff that have a rating that has only been completed by the manager. For example in the below it would total 2 as Person A has one (rating a) and Person C also has 1 (rating b).

If this is not possbible using measures, am I missing anything else before creating a new summarized table

Got you. A bit funky but here you go:

I created a concatenated column that would give me a Person + Rating so I could count that key. After that I created this measure that would give me the total occurrences of this key (I want everything that's just 1):

CountAllS = CALCULATE(COUNT('Table'[PersonRating]), ALLEXCEPT('Table', 'Table'[PersonRating]))

After this, I created a measure that counts the number of times this measure is just 1 and only for those that were rated by the manager:

Unique Count = CALCULATE(COUNTROWS(FILTER(KEEPFILTERS(SUMMARIZECOLUMNS('Table'[PersonRating], "Count", [CountAllS])), [Count] < 2)), 'Table'[Rated by] = "Manager")

Find attached my working file so you can take a dive on it 🙂

Hi @reidnmorrison ,

Your solution is great, @ray_aramburo . It worked like a charm! Here I have another idea in mind, and I would like to share it for reference.

Just create a measure, the syntax is as follows:

Count = CALCULATE(
     DISTINCTCOUNT('Table'[Person]),
     FILTER(
         'Table',
         'Table'[Rated by] = "Manager" &&
         CALCULATE(
             COUNTROWS('Table'),
             'Table'[Rated by] = "Self"
         ) = 0
     )
)

Drag measure to the report page for display:

pbix file is attached.

Why is Person C, rating a not included in your count?

Anyways the measure can be done in 2 ways (depending to the answer of my first question) :

Person Count = CALCULATE(COUNTROWS("TableName"), Rated by = "Manager")

If you need to explicitly indicate "a" rating then just modify it this way:

Person Count = CALCULATE(COUNTROWS("TableName"), Rated by = "Manager", Rating = "a")

If you need to address unique person then just use DISTINCTCOUNT([Person]) instead of COUNTROWS.

Hi, thank you for yor reply. Person C rating a is not included as they have [Rated by] entry for both "Manager" and "Self". I just need those that only have a [Rated by] "Manager". Hence I'm not sure the simple COUNT or DISTINCTCOUNT will work.
