Sum variables within unique IDs

[DrLoreto]

ID	DATE	DIST
1	04/21/15	244
1	04/21/15	320
1	05/20/15	400
1	05/20/15	390
2	04/21/15	260
2	04/21/15	310
3	04/20/15	280
3	04/20/15	320
3	05/19/15	380
3	05/19/15	410

How can I create a dataset with an average of a variable (DIST) by ID and Date from the dataset above

The final dataset should look like the following

ID	DATE	DIST
1	04/21/15	282
1	05/20/15	395
2	04/21/15	285
3	04/20/15	300
3	05/19/15	395

Use PROC MEANS with the grouping variable in a CLASS or BY statement. 

Here's an example:

try this

Proc Sql;
create table xyz as
select ID,DATE,sum(DIST) as DIST
from Data
group by ID,Date;
Quit;

Thanks for the solution, that pretty much solved it. I just changed SUM(DIST) to AVG(DIST) to get the average of the DIST values per DATE.
