Answer 1

Here's a variation on @JustinJDavies's answer, using an explicit CROSS JOIN clause:

data have;
  input NAME $ AMOUNT  COUNT;
  datalines;
RAJ     90  1
RAVI    20  4
JOHN    30  5
JOSEPH  40  3
run;

PROC SQL;
  create table combs as
    select * 
      from have(keep=NAME)
        cross join have(keep=AMOUNT)
        cross join have(keep=COUNT)
      order by name, amount, count;
QUIT;

Results:

NAME AMOUNT COUNT 
JOHN 20     1 
JOHN 20     3 
JOHN 20     4 
JOHN 20     5 
JOHN 30     1 
JOHN 30     3 
JOHN 30     4 
JOHN 30     5
