GST e-invoice System New Option: Sub Users can Access E-invoices Generated by Main Users and Perform View/Cancel/Generate EWB

Note that along with this, one or all options such as Cancel, View report and e-Waybill generation need to be provided. For example, if Enable Access to IRNs of the main user is selected as ‘Yes’ and Enable E-invoice Cancellation is selected as Yes then the sub-user can cancel the IRNs generated by the Main user also.
