SAS - Select from multiple records with same id but different status

Question

Sorry for the misleading (if there is) question title, as I don't know how to express what I need in 1 question.

I have a dataset as below:

UserId    Order    Status
1         1        completed
1         2        completed
1         3        incompleted
2         1        incompleted
2         2        incompleted

I want to select those users who have no completed status, for example, with the above dataset the result I get would be

UserId
2

Is there anyway to get the above result with SAS datastep or PROC SQL? Help is appreciated and thanks in advance.

Here's a data step approach, the proc sort will not be necessary if your data is already sorted.

data have;
input UserId Order Status :$11.;
datalines;
1         1        completed
1         2        completed
1         3        incompleted
2         1        incompleted
2         2        incompleted
;
run;

proc sort data=have;
by userid order;
run;

data want (keep=userid);
set have;
by userid;
if first.userid then num_complete=0;
num_complete+(status='completed');
if last.userid and num_complete=0 then output;
run;
