Ora-02064: Distributed Operation Not Supported

I have the FUNCTION in database A, it writes in tables at database A. It is work.
But I need to use this FUNCTION in database B, then I have created de
SYNONYM for this FUNCTION, but when I execute, I am getting the following error message:
ORA-02064: distributed operation not supported
What do I do ?

Maybe the reason for this is that the FUNCTION in database (A) is trying to do a commit. :confused:

Instead the source database (B) should control this commit.
