Your GROUP BY tells SAS at what levels to calculate. From your code snippet it looks like you've included Number in your GROUP BY when the numbers are different across the observations. SAS is correctly calculating what you've requested. Remove Numbers from the GROUP BY and Select statement. If you want to include it in the SELECT you'll need some sort of rule, ie max/min of which one to take. If it's first or last then then you'll need to go back to data step logic.

Here could give you a start :

 

 

option datestyle=mdy;
data have;
input id $ Number  (Starttime Endtime) (: anydtdtm.);
format Starttime Endtime datetime.;
cards;
1a. 23 01/01/16:11:01:00  01/01/16:11:05:11
1a. 24 01/01/16:11:02:00  01/01/16:11:06:16
1a. 25 01/01/16:12:00:00  01/01/16:12:07:00
;
run;
data temp;
 set have;
 if lag(Endtime) lt Starttime or id ne lag(id) then g+1;
run;
data want;
 set temp;
 by g;
 retain start num;
 if first.g then do;start=Starttime;num=number;end;
 if last.g then do;end=Endtime;output;end;
 format start end datetime.;
 drop Starttime Endtime number;
run;

Hi thank you everyone e that is assisting me ...whst I have is a data set that looks like this
SITE. NUMBER. START TIME. END TIME
123. A3 06dec2015:8:24:00 .06dec2015:08:26;00

123. A3 06dec2015:8:26:00 .06dec2015:08:40:00

What I want is the min an max of those 2 entries nothing else something like this

123. A3 06dec2015:8:24:00 .06dec2015:08:40:00
The other 2 can be removed
What I'm getting is all 4 entries or just the min
123. A3 06dec2015:8:24:00 .06dec2015:08:26;00
Thank you again

BTW there are other dates in my data sometimes it brings those dates as my min an max for example
123. A3 03dec2015:8:25500 .06dec2015:08:26;00. Which means it's looking st who data I need it to look at each day spefic
