GSTR1 Amendment

Anirudh (Student) (299 Points)

Original invoice reported in GSTR1 May 2018 with GSTIN of receiver XYZ

Now I want to amend the invoice with different GSTIN of receiver ABC.

But the portal is not allowing to change GSTIN.

All other details of this invoice were correctly reported in May 2018 return itself.

What can be the alternate ways for posting this correction?
