Left Anti Join Not working for one measure out of 8 done correctly

Anonymous — Mon, 20 Sep 2021 18:45:47 GMT

Hello All. So I did 8 Anti Joins that worked and 1 that is not working. The date is the same so I am unsure how to managed this.

Here is what my data looks like in Power BI:

This is the Numerator and I just want to subtract ALL of these regardless of ID # from the Denominator which is

AFTER this pic:

The count I am getting is 546,470 rows where I need 352, 930 which is the DIFFERENT

between the DENOMINATOR (609,196)and the NUMERATOR (256,266 rows)

I cannot understand what I am doing incorrectly as I just did a left anti join (the denominator 1st then the numerator on the bottom)

Anything else I can try? I already tried this but I need the actual PCR_ID #'s in a table which a merge accomplishes.

Note that Power Query is case sensitive (as opposed to DAX). Can you reproduce the issue with a smaller data sample?

Thanks..by case sensitive are you suggesting that if the common column to join the two tables is not the same case it will not recognize it, etc? I cannot reproduce the example as I dropped it form my report.
