Maybe, maybe not
The sample data may be TOO simplistic
Question - for each DID Num, can there be multiple instances of the same status
In which case - do you want the earliest or the latest instance of the record?
The examples below - for the same DID Num - there is more than one record for the same date and time, but different Status

I have a table that has 3 keys, numeric "reckey", date,time.status code.
The table is basically a tracking table for a pick ticket# through the
warehouse.

I want to retrieve the only the highest status record for each numeric
key. Some sample data:

DID Num Entry Date Time Status
Code
15612285 2017-08-31 2150 10.0
