BAPI for GI and GR reversel

Hi Guys,

Is there any BAPIs available for Reversing the GR and for reversing GI in 4.6C version of SAP.

I have to use transaction MBST for GR reversal and VL09 for GI reversal. After reversing i have to use VL02N for GI posting and custom transaction for GR posting. Instead of going for BDC let me know if there are any BAPIs or FMs available for the above scenarios.

Thanks in advance,

Vinod.
