GR & GI for production Order

Hi Team,

I am posting production order confirmation in SAP through interface. The confirmation details will sent from external system to SAP through interface. When this interface is triggered in SAP, the goods receipt for production order header & goods issue for production order components to be posted separately in SAP (No Back flush is setup in my system). Do we have any BAPI / FM for GR & GI posting in SAP?

Your guidance is very much appreciated.

Thanks
