Oracle

I have a function with some Savepoint in it as below

Create Or Replace Procedure TestRollToSave
As
Begin
	Delete From TestQuote;
	Insert into TestQuote Values (111,'aaa');
	Insert into TestQuote Values (222,'bbb');
	savepoint a;
	Insert into TestQuote Values (333,'ccc');
	savepoint b;
	Insert into TestQuote Values (444,'ddd');
	Insert into TestQuote Values (555,'eee');
	Insert into TestQuote Values (666,'fff');
	savepoint c;
	Insert into TestQuote Values (777,'ggg');
	Rollback to b;
End;
/

And i have a another schema i have created a link between two schemas and i am calling this procedure through link as below

Exec TestRollToSave@R2link;

And i am getting output as below.

Select * From TestQuote@r2link;

         A B
---------- -------------------------------------
       111 aaa
       222 bbb
       333 ccc
       444 ddd
       555 eee
       666 fff
       777 ggg

Means the rollback to savepoint is not working.

Can anyone please help me to overcome this.

I am not getting error also.

For more information the two schemas are in same service.
But if the both schemas in different service then it is working fine.
