excel array formula

wonder if someone can help me.
I have a list in excel that contains the same sku more than once on a
workbook in no paticular order, however i want to bring back the last
time that this sku appeared on the workbook for example:


SKU 271562 date counted 11 september
SKU 275555 date counted 12 september
SKU 271562 date counted 12 september
sku 255212 date counted 13 september
& so on
SKU 271562 date counted 11 october


The date range is only applicable to the date counted therefore i
cannot search via a date


Can someone please help

Gordon,
If I have understood correctly:
1. Each line in your sample occupies a single cell.
2. All lines are of the format: SKU xxxxxx date counted dd mmmm
Therefore, the number of characters until the date starts is fixed. So
is the length of every SKU code. With these assumptions, and assuming
data are in column A:A, you will use some auxiliary columns


B1: =left(A1, 10) -- this extracts the SKU
C1: =value(mid(A1, 24, 20)) -- this extracts the date in number format.

You can format column C:C to a date format if you want.


Now, given an SKU in a cell, say K1 contains "SKU 271562":
=max(C1:C100*if(B1:B100=K1, 1, 0))


Supply the necessary ranges in the formula and enter it as an array
formula, Shift+Ctrl+Enter.

this didnt work.
what the problem is the workbook in question can have the same sku
appearing multiple times.
I have with the help of someone been able to extract the date the sku
was last counted,however i am unable to bring back total qty and qty
counted for the date.
so for example...

SKU 277252 qty 20 counted 50 date 3rd october
I then have a different SKU and another and so on
the next time i count this sku might be today
SKU 277252 qty 10 counted 40 date 10th october

i can bring back the date with an array formuala but am struggling to
bring back the qty and qty counted ..

Please help

Are you trying to determine the last occurrence of a SKU in a range,
irrespective of the date it is associated with?

[1] The SumProduct function should implicitly coerce the truth values to
their Excel numeric equivalents.
[2] The lookup functions should have an optional argument for the return
value, defaulting to #N/A in its absence.

THE SAME SKU CAN APPEAR MULTIPLE TIMES ON THE SPREADSHEET.i HAVE WITH
SOMEONES HELP BEEN ABLE TO DETERMINE THE LAST TIME IT WAS COUNTED.
HOWEVER I WANT TO BRING BACK THE QTY AND QTY COUNTED AS WELL.
FOR EXAMPLE:

SKU 276262 QTY 10 QTY COUNTED 12 DATE 5TH DEC
THEN ANOTHER SKU
AND ANOTHER
THEN THE SKU RE-APPEARS WITH DIFFERENT QTY AND DATE

I WANT TO BRING BACK THE QTY AND QTY COUNTED THE LAST TIME IT WAS
COUNTED

Gordon,

There is no need for capitals. Also, why don't you post the formula you
cooked up with the help someone else. That would help to determine your
layout and the conditions for the retrieval. I'll venture a guess:

X2:

=MATCH(2,1/((SKUrange=SKU)*(QualificationRange="COUNTED")))

which must be confirmed with control+shift+enter.

W2:

=INDEX(DateRange,X2)

Y2:

=INDEX(QtyRange,X2)

Z2:

=INDEX(CountedQtyRange,X2)

Is this even close?

Apologies,
this is the formula that bring back the date no matter when the sku
appears
=max(C1:C100*if(B1:B100=K1, 1, 0))

C includes the date and B is the SKU.

i now want to bring back the qty and qty counted

=SUM((MAX(IF(B1:B100=K1,C1:C100))=C1:C100)*(B1:B100=K1))

again as an array formula

Assuming that (a) Qty is in D1:D100, (b) Qty Counted in E1:E100, and (c)
the dates for the same SKU is increasing vith every new occurrence...

L1:

Either...

=MAX(IF(($B$1:$B$100=K1),ROW($B$1:$B$100)-ROW($B$1)+1))

which must be confirmed with control+shift+enter.

Or...

=LOOKUP(2,1/($B$1:$B$100=K1),ROW($B$1:$B$100)-ROW($B$1)+1)

If (c) does not hold:

=MATCH(MAX(IF($B$1:$B$100=K1,$C$1:$C$100,"")),IF($B$1:$B$100=K1,$C$1:$C$100),0)

which must be confirmed with control+shift+enter.

M1:

=INDEX($C$1:$C$100,L1)

yields the associated date.

N1:

=INDEX($D$1:$D$100,L1)

yields the associated quantity.

=INDEX($E$1:$E$100,L1)

yields the quantity counted.

Note that the foregoing setup seeks efficiency. Determine the position
of the SKU and retrieve the associated values with a simple INDEX
formula which is fast.
