While filing GSTR-3B for the month of July 2018, I have exlcuded supplied made to unregistered persons. In Table 3.1 of GSTR-3B, I have shown Sales made to Registered Persons only. In Table 3.2 of GSTR-3B, I have shown Inter State sales made to Unregistered Persons. As I have shown less sales in Table 3.1 of GSTR-3B net of sales made to unregistered persons, electronic libility ledger is showing less liability than what I have shown in GSTR-1. Can I rectify this mistake while filing GSTR-3B for the month of Aug 2018 by increasing proportionate liability than what will be shown in GSTR-1 for the month of Aug 18
