Impact of Export Sales CN on Refund on Export - Goods and Services Tax - GST

Dear Experts One of our client have Export of Rs. 10.00 lakh during December 2023. Here one of Invoice having Sale Value Rs. 1.00 lakhs for which order cancelled after reaching the Goods at Dockyard hence we issued CN against that Invoice. Now while calculating Amount of Export Sales for refund purpose as EGM was not generated for original Invoices that was not getting uploaded online on Export Sales Annexure B and CN was again reduced by Department while assessing Refund hence Export Sales considered Rs. 8.00 lakhs instead of Rs. 9.00 lakh. Here CN issued in Same month i.e. December 2023. Kindly advise with legal Supporting. Here Second scenario what if Sales got cancelled in Next months and CN was issued in January 2024.
