Rule 03: Cross-posting Without Telling Us

Your post does not comply with Rule 3 of our Forum RULES. Do not cross-post your question on multiple forums without telling us about your threads on other forums.

Post a link to any other forums where you have asked the same question.

Cross-posting is when you post the same question in other forums on the web. The last thing you want to do is waste people's time working on an issue you have already resolved elsewhere. We prefer that you not cross-post at all, but if you do (and it's unlikely to go unnoticed), you MUST provide a link (copy the url from the address bar in your browser) to the cross-post.

Read this to understand why we ask you to do this.

I have added the crosspost reference for you today. Please comply with this and all our rules in the future

Try this Array Formula to get total sales,

=SUM(SUMIF('Data set'!B:B,IF(B$2:B$1696=D2,A$2:A$1696),'Data set'!C:C))

In the 2nd, please clarify what do you mean by sales from September onwards.

Hello Silverboy,

This is an array formula (**Array formulas are not entered in the same way as 'standard' formulas. Instead of pressing just ENTER, you first hold down CTRL and SHIFT, and only then press ENTER. If you've done it correctly, you'll notice Excel puts curly brackets {} around the formula (though do not attempt to manually insert these yourself)).

2) ...so do you you want excel to look since 2019 Sep - 2020 Aug? also are the dates exactly in your data sheet or is it real date & formatted as yyyy-mm?

Look at the attached and advise if this is the direction you wish to go. It is completed by merging (joining) the files in Power Query and then grouping them to meet requirements.

EDIT: Just read in your latest post that you are on a MAC. My solution will not work for you. Power Query is not an option on a MAC. Please update your profile to indicate that you are running Excel on a MAC and the version number so that helpers do not waste time on a solution that will not be appropriate for you. Not all versions of excel offer the same features.

Formulas are applying in Lookup tab and all are Array Formulas.

F2,

=SUM(SUMIF('Data set'!B:B,IF(B$2:B$1696=D2,A$2:A$1696),'Data set'!C:C))

G2,

=IF(F2,INDEX(TEXT(date(2018,9,1)+{1;2;3;4}*29,"yyyy-mm"),MATCH(1,FREQUENCY(0,1/(MMULT(SUMIFS('Data set'!C:C,'Data set'!B:B,TRANSPOSE(IF(B$2:B$1696=D2,A$2:A$1696)),'Data set'!A:A,TEXT(date(2018,9,1)+{1;2;3;4}*29,"yyyy-mm")),ROW(B$2:B$1696)^0)+ROW(A$2:A$1696)/1000000)),0)),"")

then copy down.

G2 formula will look this way.

If month is in 2018-09, 2018-10, 2018-11, 2018-12
Postcodes are from associated store #

Attached is the file.

Here's my solution;
Sheet Dataset: Column D and E is lookup store # and month convert to real 1st dys of month-year
Sheet Lookup
From F to AE is every month sales from month to month given in G1 and I1
AG to AQ is rank of monthly sales from 1st to, i.e, 5th
