Count Unique based on two/three different criteria

[Melimob]

Hi There

I have a data set with multiple columns where I need to count the unique fields in a seperate tab based on multiple criteria.

PNR	Booking Date	Booking Agent	MAX Booking Agent ID
AAVBHD01	10/09/2018	AO	99355
AAWTZK01	05/09/2018	BM	86788
ABDYNH01	10/09/2018	GM	23023
ABGRLL01	05/09/2018	SW	25238
ADVQJQ01	04/09/2018	AO	99355
AENSSR01	10/09/2018	JP	14647
AFFGNM01	05/09/2018	PB	28180
AGJTEJ01	04/09/2018	SD	23509
AGJTEJ01	04/09/2018	SD	23509

1 - I want to only take the first 6 characters from PNR column
2 - I want to summarise how many unique times column A (PNR) + column D (MAX ID) appear together
3 - I also want to summarise point 2 plus month of booking date

I can do it by copying to a diff sheet, removing duplicates and then using countif formulas but in case I wanted to just read from the raw data tab without copying/removing, is there any formula I can use?

Many thanks

What does 1 mean - a listing of the first six items from PNR?

What is the expected value for 2?

Item 3 needs some elaboration what it amounts to.

Hi Aladin

Point 1 means I only want to analyse unique codes based on the first 6 characters (i.e. exclude last 2 digits..01)
Point 2 so for example, this set should say: Max ID 23509 = 1 PNR since Max ID 23509 = 1 PNR since AGJTEJ should only be counted once as unique for this MAXID
Point 3 is: In Sept, Max ID 23509 = 1 PNR since AGJTEJ should only be counted once

Obviously my data has a whole load more where PNRs may appear multiple times for the same MAXID (counted as one) or different MAXID's (counted per MAXID).

Many thanks

Hi - thanks all but I found something on internet and works a treat!
=SUM(IF([@[Max ID ]]=Table2[MAX Booking Agent ID], 1/(COUNTIFS(Table2[MAX Booking Agent ID], [@[Max ID ]], Table2[PNR Stripped], Table2[PNR Stripped])),0))

CTRL+SHFT+ENTER

Thank you
