Hi,

I have a table of data with approximately 5000 rows. I need to assign the same batch number to each row for an item list where another column changes its value occasionally, and may not be ordered (it can be if needed), but I need to limit the number of items in a batch to 500. The data in the Group column could be any text e.g. Time Zone

I am looking to achieve a very similar result to this thread, which gets most of the way there, but where it would increment the batch number if it reached a limit of the number of items in a batch e.g. 5 (but need to be able to change this limit by adjusting the value in the formula).

Item List | Group | Batch (limited to 5 items within a batch)
---------------|----------------|------------
Item 1 | Property A | 1
Item 2 | Property A | 1
Item 3 | Property A | 1
Item 4 | Property A | 1
Item 5 | Property A | 1
Item 6 | Property A | 2
Item 7 | Property A | 2
Item 8 | Property A | 2
Item 9 | Property B | 3
Item 10 | Property B | 3
Item 11 | Property A | 2
etc.

Appreciate the help!

Clicked submit to soon. The answer that was provided by Eric W is this:

=IFERROR(IF(COUNTIF(A$2:A2,A2)=1,MAX(B$1:B1)+1,INDEX(B$2:B2,MATCH(A2,A$2:A2,0))),"")

Can you post some sample data.

MrExcel has a tool called “XL2BB” that lets you post samples of your data that will allow us to copy/paste it to our Excel spreadsheets, so we can work with the same copy of data that you are. Instructions on using this tool can be found here: XL2BB Add-in

Note that there is also a "Test Here” forum on this board. This is a place where you can test using this tool (or any other posting techniques that you want to test) before trying to use those tools in your actual posts.

Also what version of Excel are you using?
I suggest that you update your Account details (or click your user name at the top right of the forum) so helpers always know what Excel version(s) & platform(s) you are using as the best solution often varies by version. (Don’t forget to scroll down & ‘Save’)
