Hey folks. I used to use this all the time and its fallen out of memory since a lot of this is a perishable skill....

I have many vendors, across a list of buyers. Some vendors belong to just one of our buyers, sometimes the buyers share a vendor.

I have a "count distinct" to show how many distinct buyers are buying one vendor. When I expand the table out to show the buyers however, the count distinct then shows all "1" because I dont have the filter context right in the formula. For example....

This formula:
=DISTINCTCOUNT([Buyer])

Gives me this when I have all my fields collapsed,

Vendor #​
Vendor Name​
BUYER​
distinct count buyer​
1234​
VENDOR A​
3​
7654​
VENDOR C​
2​
9999​
VENDOR B​
1​
34567​
VENDOR D​
3​
Grand Total​
9​

But when I expand out the vendor column to show the constituent buyers, those distinct counts all now show "1".
Vendor #​
Vendor Name​
BUYER​
distinct count buyer​
1234​
VENDOR A​
JONES​
1​
1234​
VENDOR A​
SMITH​
1​
1234​
VENDOR A​
DOE​
1​
7654​
VENDOR C​
HAMPTON​
1​
7654​
VENDOR C​
LINCOLN​
1​
9999​
VENDOR B​
DOE​
1​
34567​
VENDOR D​
OCONNOR​
1​
34567​
VENDOR D​
WASHINGTON​
1​
34567​
VENDOR D​
WILLIAMS​
1​
Grand Total​
9​

How did I need to change the formula to ALWAYS remain showing that distinct count of buyers (within each vendor name/number, whichever you decide)? I vaguely recall some mix of ALL, CALCULATE, FILTER....and so forth but its all a fog to me now, been a while since Ive seriously commited myself to dax, and it shows.
 

Excel Facts

Test for Multiple Conditions in IF?
Use AND(test, test, test, test) or OR(test, test, test, ...) as the logical_test argument of IF.
Not sure what you expect there. You're grouping by BUYER so the count is 1 for each of them.

correct, but if you look at vendor A, i want the pivot to always indicate the count of distinct buyers is 3 no matter how I choose to expand/collapse my filters. There was a way to do it with DAX but I cant remember. Just because it preserved the continuity of that filter for the particular analysis I was doing.

Doesn't make sense to me, but you'd want something like:

=CALCULATE(DISTINCTCOUNT(Tablename[BUYER]),ALLEXCEPT(Tablename,Table2[Vendor Name]))
