Respected Experts.

An invoice bearing No.Ex-017/26-27 dated 27-07-2026 was filed in July 2026.. Actually the date of Invoice is 09-08-2026.

How do I rectify the error in GSTR1? The amendment section is not allowing to change the date to later date as it was filed in July 2026..

Your valuable advice may help me a lot

Thanks & regards
