Is there is any BAPI/FM/LSMW for BOMBOS Interface?

I have a requirement to write a custom program to transfer BOM to BOS. This we can do through CG37, But I want to execute CG37 functionality through custom program. Could you please let me know if any one knows BAPI/FM/LSMW for this? Thanks in advance.
