Possible solution approach

Incase of Sales : Wrongly issued to other GSTIN

Step 1 : Pass Credit note to reverse the entry which is showing in portal (show this entry in next return period)

              Above entry will nullify the incorrectly issued invoice using credit note

Step 2 : Now pass fresh Sales invoice with correct GSTN in next return period (show this entry in next return period)

             Above entry will provide correct GSTN and other details properly
