I have a dataset where I need to make sure that each like ID gets assigned the same Value. It's not so much that I need to select a specific value to repeat from all that are assigned to the like ID, but that I need all the like IDs to have the same Value.
Data Have:
Id Value
101 656
101 756
101 805
101 752
501 999
502 405
502 365
Suppose you had the chosen values in a dataset have2 (completely made up based on the values you're displaying):
ID Selected
101 656
501 999
502 999
Then a PROC SQL left join will do the trick:
proc sql;
select t1.id, t1.value, t2.selected
from have as t1 left join have2 as t2
on t1.id = t2.id;
quit;
