How to Keep Duplicated Variables based on the Value of another Column

Hello all!

I am working on cleaning up a dataset, and I do not know how to do so. Here are some of the relevant parts of the data set that has approximately 400,000 observations, with duplicates based on an ID number. What I want to do is keep the case IDs that correspond to the highest outcome. So, for the following:

ID Number	Date	Outcome
3	2/2/22	4
3	2/2/22	3
3	2/2/22	3
3	2/2/22	2

I want to keep only the first row because it has the highest code. Some IDs have 5 corresponding values for outcomes; some have 2; I think one even has 10.

I have tried to google this, but got very confused by duplicates and dups. I'd really appreciate any suggestions anyone has.
