Rollback in Oracle Adapter..Urgent

Hi

Iam calling two stored proc say “A” and “B” in one integration component. If the procedure “B” fails i need to rollback the procedure “A” also.

Iam using branch step in between the Procedure configuration to check the return values from the stored proc.

The problem is that if i use any steps in between the stored proc calling the procedure “A” is not rollbacked if proc “B” fails.

Is there any way to handle this issue?

Thanks
Shibu
