Yes.

I bet IBExpert has some kind of commit/rollback afterwards.

Transactions are controlled at the CLIENT side. So if you're
calling SP1 and SP2 from the _same_ transaction, both will
see the same data.

So if SP1 calls SP2, then SP1 should be able to read the data
that SP2 inserted. If not, you have another problem.
