This sounds like a candidate for a trigger rather than a
Stored Procedure, but it sounds as if you are expecting the
Stored Procedure to do something that it will not - pick up
data from another transaction?

I don't think this is a problem with IBO, but rather your
logic. If two users are both posting updates to the one
record, you have a problem. User 1 will get a ballance, and
add or subtract from it. User 2 will see the same original
ballance until User 1 commits a change. Then User 2 needs to
know that they can or cannot proceed if there are
insufficient funds, so they need to be refreshed or stopped
from doing their update. Is the Stored Procedure managing to
bypass this checking, and so User 2 makes a change further
change to the ballance based on the uncommited starting
point, rather than the later User 1 resulting ballance?
