Amendment for GST R1 for second time am

This discussion addresses the possibility of amending a GST R1 return for a second time. The user mistakenly entered the wrong GST number for invoices filed in June 2019, which were already amended in November 2019. While one suggestion proposes trying the same amendment method again, the consensus is that a second amendment might not be possible. The recommended solution is to reverse the incorrect invoices with credit notes and issue new ones with the correct details.
