Ranking tiebreak problem

[Mtyler]

All

I'm trying to rank data in largest to smallest order, with a tiebreak for identical items. The tiebreak sorts by size based on a second variable.

I'm using this formula:

=RANK($BP8,$BP$8:$BP$360,0)+SUMPRODUCT(--($BP$8:$BP$360=$BP8),--($K$8:$K$360>$K8))

This has worked brilliantly, but I've recently come across a problem where I have items ranked the same. It seems to derive from the two parts of the formula.

ie I have 5 items with $6m, which are ranked as 52 (using rank formula), and the tiebreak adds on anything from 0 to 5 (using the sumproduct part). However, I also have multiple items as $5.5m, which are ranked as 51, and add on another item (from the sumproduct amount).

This leads to items with the same ranking (ie 52+3 and 51+4). Any thoughts on how to fix for this? Using Excel 2003.

Thanks in advance

Have the tiebreaker value be a deceimal value instaed of a whole number. Then the tiebreaker value will be small enough to break the tie but not large enough to change a rank.

=RANK($BP8,$BP$8:$BP$360,0)+(SUMPRODUCT(--($BP$8:$BP$360=$BP8),--($K$8:$K$360>$K8))/100)

Thanks - I had considered that but wondered whether the rank formula only worked on whole numbers or not - will check.

Thanks

Have just realised that I am reliant on the tiebreak being an integer as I pull through information based on the rank.

Is there another solution to this?

Thanks

Alpha - thanks for this, although it doesn't allow for a tiebreak based upon a second condition (merely it ranks ties based on their position in the list).

Perhaps you could give and example set of data and the expected result ranks.
