Count ifs and percentages

[Jayfemi]

i am with tow  data sources and i  want to count the amount of times a name appears in each data source and then do a percentage  for example

Data Source 1 John Doe = 250

Data Source 2 John Doe = 4

in this case 4 is 1.6% of 250

@Jayfemi,

Firstly, create the following measure in the first table.
Count1 = CALCULATE(COUNTA(Source1[name]),FILTER(Source1,Source1[name]="John Doe"))

Secondly, create the following measure in another  table.
Count2 = CALCULATE(COUNTA(Source2[name]),FILTER(Source2,Source2[name]="John Doe"))

Then create percent measure in the first table using dax below.
percent = [Count2]/[Count1]

If the above steps don't help, please share sample data of the two tables.

Regards,
Lydia

Create a bridge table between your two data sources that contains a single unique value from each of the two data sources. Use this single table to create a relationship to both of your data sources.

If you want to do it with a specified name, you can do countrows with a calculate. 

It sounds like you might want to create measures similar to this:

[CountTable1] = Countrows(DataSource1[Name)

[CountTable2] = Countrows(DataSource2[Name)

[%InBoth] = Divide([CountTable1],[CountTable2]) >> please note that I don't know what the appropriate numerator/denominator is so please decide yourself, and if you want to only show names that occur in both data sources please try

    If( [CountTable1] && [CountTable2], Divide(x,y))
