DB link not showing the required O/P

Question

Dear All,
I am accessing a Procedure via DB Link from database A to B (database on which procedure is build), returning four O/P's.
When i execute this procedure in A, it only returns 2 outputs, but when the same is executed in B, it returns 4 outputs.
we are executing the procedure using same decalaration.

But when we run the same procedure in database B i.e. the source DB for the procedure, we get four O/P.Three things that I could imagine:
a) Different privileges
Does the DB Link work with the same user as if you are accessing the data directly?
If not test on database B with exactly the same user that is used via DB link.
b) Uncommited changes.
Did you commit all changes on both databases? Maybe one session sees new records that are not commited yet, or the other doesn't see deleted records.
c) Strange/unlucky select, that results in different output.
Show us the select that you do. I just noticed that you metioned a procedure. How do you call the procedure from the DB link? What does it do?
