FI-GL Extractor logic in HANA

Hi Experts,

We have a requirement to implement FI-GL(0FI_GL_4)  and  FI-SL (0FI_GL_6) extractor logic in SAP HANA. We have extracted the base tables GLT0, BSEG and BKPF in SAP HANA.

Could anyone give pointers on the FI  Extraction Logic  or some use case scenario.

Thanks in advance.

Regards,

Priyanka
