Question27:  
We face problem as per below, Please advise us. 
Issue 1: We have cleared goods for export on payment of IGST. While filing particulars in Form 6A, invoice number is required to be shown. If IGST invoice number is shown, that will not match with invoice number shown in Shipping Bill, as in the Shipping Bill export invoice is mentioned.  
Issue 2: GSTR-1 shows error when the date of Shipping Bill is prior to date of tax invoice. The GSTR-1 does not accept the details of export.  

Answer:  
This is a practical problem we are giving you a thumb rule for always it is as follow
Don't worry when there is a problem relating to GSTN because lot of changes are required in GSTN and every day the service providers are doing required changes in it Whenever the system is not responding to working then take a screen shot send an application to help desk also write to your GST officer and keep on giving reminders to create pressure in case of refund of all types file a manual copy and do follow up. There is only one thing at your part that is you have deposited all tax in time and tried to file all returns in time. There is no other possible suggestion. (Reply Dt. 01/01/2018)
