Counting occurrences of products in a master list
 

I want to count the number of occurrences of a small list of products that
appear in a large (2,000+) inventory list. I used the countif function but
there's a specific situation where my formula fails. Here's the example of
the product numbers in the small list:

R6AA
RM8B
RN7A
RN7AA
RN7A/5
RN7AB

The product numbers in the master inventory list may be 3 to 12 characters
in length. Some of them include the / separator which designates a subset of
the master number to the left of the /.

For example, the fifth item (RN7A/5) is the same as RN7A. I would like any
products with the / character to be totaled with the "root" item (the number
to the left of the /).

The product numbers are in random order in the inventory list, column A. The
couple of dozen items to be searched and counted are in column F.

I started in column H1 with =countif(A1:A2000,f1) and copied down. As long
as I include RN7A and RN7A/5 in column F, this works fine. I get my totals
but the subsets are not combined.

I would like to only specify RN7A and it's total would include all subset
products /5, /7, /G4, etc. too.

Can anyone provide a formula to accomplish this goal?

Try
(I tested in Excel 2007)

=SUMPRODUCT(--(LEFT(A1:A2000,Len(F1))=F1))

Another possibility:

F1 = RN7A

=COUNTIF(A1:A2000,F1&"*")

I had tried this but it picks up any combinations, for example it will count:

RN7A
RN7A/9
RN7A/G4

but also

RN7AA
RN7AB
RN7AX... etc.

I see there's another suggestion which I haven't tried yet.

Thank you for your answer!

So, you only want to count cells that contain RN7A or RN7A followed by a / ?

Try this:

F1 = RN7A

=COUNTIF(A1:A2000,F1)+COUNTIF(A1:A2000,F1&"/*")

I see there's another suggestion which I haven't tried yet.

That'll do the same thing as my original suggestion.

Counting occurrences of products in a master list
 

I see I should be top posting... sorry...

This one is closer but not 100%.

When searching for RN7A in the list, it ignores RN7 (correctly) and counts
RN7A, and RN7A/5 as expected. But it also counts RN7AA and RN7AB, which it
should not.

I can verbally say what the formula should do, but I can't put it into a code!

"Look for F1 and count the occurrences in the range A1:A2000. And also, look
for F1 with a trailing / character and add those occurrences to determine the
total"

The formula needs to do two simultaneous counts and add them together.

YES! That seems to do it, and it follows the "saying the formula" example I
gave. It always looks so simple, after someone figures it out for you!

Thank you very much!
