How do I select cases based on multiple variables

For my research I would like to keep only certain record_ids.
I have multiple measurements per day, which I have to break down to only 1 measurement per day, based on the 'accuracy' of that measurement.
I have created an accuracy variable '..._choice', which gives numbers to whether it is a first choice variable, or a second, third etc.

So how do I select/keep the cases with 1 measurement per day with the highest choice?

Thanks in advance!

You could maybe describe the structure of your datafile, for eacxampe what is contained in the rows and what is contained in the columns.

With kind regards
