There are cases where you may want to filter the data that is displayed in the Top 5, Top 10, Top 20, etc. To do so, you need to update the formula that generates those numbers. It is found under the MCT Formulas page. It is locked, but you can edit it if you absolutely must. This would be one of those cases. You should see the following when you open this page:

The top row with the 0’s houses the formulas we will need to change. A common reason to edit this row would be to filter out queries with less than 3 impressions. To do this you will edit the formula in every cell on row 2. A good template will be to use cell B2. The formula below is what you would paste in cell B2:
=COUNTIFS('Previous Month'!$E:$E,"<5.001",'Previous Month'!$C:$C, ">3")
After changing that, you can copy it across the row. From there, you will edit the four columns C-F. In column C, Top 10, you will change 5.001 to be 10.001. In column D, Top 20, you will change 5.001 to 20.001. Etc.
***IF YOU’RE DOING THIS ON AN EXISTING REPORT, GO ON. OTHERWISE, YOU’RE DONE!***
After you have edited all four columns, you will copy row 2 columns B-F to the clipboard and go over to the Monthly Cumulative Totals sheet.
Beginning in row 2, paste the copied formulas to columns F-J. You will then highlight the cells you just pasted to that region and press CTRL + h. That will bring up the pop up shown below:

This is going to perform a find and replace on that region. In this case, we want to find “Previous Month” and replace it with “Jan 2018” (you will replace it with whatever MMM YYYY the row is referencing). You then have it search within formulas and click Replace All, then Done.
From there, you’re going to perform the find and replace on every successive row with data. What I do, is copy the region I just performed the find and replace on, then go to the next row and paste it there. Then when I do the find and replace, I can find “Jan”, and replace it with “Feb”. It makes it a little bit faster.
That’s it! You’re done!
