Are there new changes for creating blocks in business rules?

Hello,

we noticed that some of our calculation logics do not work anymore as expected and are wondering whether some updates from Oracle to the database could be the reason for that. In particular, did anyone notice a change in using creating block commands like "@CREATEBLOCK" in calculation rules? It seems that only the command "SET FRMLBOTTOMUP OFF" is working.

When we build the logic last year everything worked smooth, however since we converted the system from forms 1.0 to forms 2.0 and also did some minor changes which do not effect the calculation logic the old rules seem not to work anymore.
