India GST Configuration through Base E-Business Tax Module

Hi,

We are trying to leverage standard E-B Tax Module for India GST Implementation, and facing challenges while deriving both SGST & CGST for the same Invoice Line.

Also, please suggest the ideal Regime to Rate Flow, considering multiple GST Registrations and the required to have Tax GL Codes separately for each State.

Option 1: One Regime (IN-GST)-One Tax (GST)-Multiple Tax Rates (SGST STD, CGST ST, IGST etc.)
Option 2: One Regime (IN-GST)-Multiple Taxes (SGST, CGST, IGST etc.) -Multiple Tax Rates (SGST, CGST ST, IGST etc.)

Option 3: Multiple Tax Regimes (SGST, CGST, IGST etc.)-Multiple Taxes (SGST, CGST, IGST etc.) -Multiple Tax Rates (SGST, CGST ST, IGST etc.)
