We had exported goods to Kenya with IGST and had entered the sales details in GSTR 1 for the month of January 2019. We contacted the helpdesk of Icegate website to know our refund status. They said that our shipping bill has been processed with a response code "SB000: Successfully Validated", and requested us for scroll generation. How to generate scroll? What is the process of generation of scroll number? Please help.
