Is there any work around?

 I looking for solution for commit, rollback with in function.

You can't use transactions within functions, use savepoints instead.

It unfortunately can't be done from within the database.  There is
only one workaround -- using dblink or similar technology to connect
back to the database inside your function to bend/break transaction
rules.

In the 9.0 world, this (no implicit transaction state pl code,
possibly termed 'stored procedures') is one of the top two or three
requested features.
