We are exporters of Spices from Tuticorin Port.

We do exports under LUT

When goods are removed from my go down in Trivandrum  to be transported to Tuticorin we generate e invoice and e way bill  with the customs rate of exchange.

Once the goods reach Tuticorin the samples are drawn by Spices Board and tested for quality. The will be available within a week..

After this the goods are taken to port for export  but at the time of let export the rate of exchange sometimes Changes.

At the time of claiming refund /filing GSTR 1  there is a difference in the e invoice value and the value as shown in Shipping Bill and hence GST system shows error. As there is no provision to amend e invoice we are helpless

Kindly give your suggestions on how to resolve this issue
