What have you tried? SQL or Data step?

If you're not familiar with merges at all, the documentation has a full set of examples here (with code and data examples):

You want to look at one to one merging or match merging section.

Can you post the code you tried?

[Astounding · Accepted solution]

Here's the simplest program that might work:

data want;
   set A;
   set B;
   keep id tna ret;
run;

If you were to actually describe your intentions, a better program might be possible.  This program just matches observation by observation:  first from A with first from B, second from A with second from B, third from A with third from B, etc.  Perhaps that is what you want, but if not you will have to do more of the work.
