Hi,
Thanks for your suggestion. I don't think this is due to the data issue from Adobe. I validated other date ranges and I am still seeing the same issue.
If we consider that the "Approximate Distinct Count" is miscalculating, how can it me corrected? or is there any other to calculate the "Number of Unique Values" for a dimension?
I was just playing with a dimension on our side...
Based on the "breakdown" column, I should have approximately 479K rows, but the Approx. Count Distinct was only showing 475K.. so I was 4K short...
So, I tried to make my own calculated metric.
First I started with an IF statement:
IF [
logical_test [
(Dimension X exists)
Occurrences
]
value_if_true [
static number = 1
]
value_if_false [
static number = 0
]
]
This returned 1 on every row of my dimension (including the total), which is what I wanted...
Then, I edited the metric again, wrapping the above IF statement inside a COLUMN SUM function.
This now returns a match to my number of rows, i.e. 479K. Note, this will show on ALL rows, it won't be like the Approx Count Distinct where each row will show 1 and the total will show a total... every row is the column sum.
