BAPI/FM to create commitment item which can be commit/roll back externally

Hi experts,

Is there any BAPI/FM to create commitment item????

I can use BDC but problem is that it can't be roll back. In my requirement i want to roll back based on condition.

i am creating GL and commitment item, if GL creation is failed commitment item should be roll back.

Is there way to solve this issue ? please help me.

Thanks in advance.

Regards.
