1. Auto calculation of route distance based on PIN code for generation of EWB: E-waybill system is being enabled to auto calculate route distance for movement of goods, based on the Postal PIN codes of source and destination locations, given by the user. The e-waybill system will calculate and display the actual distance between the supplier and recipient addresses. User is allowed to edit the distance shown, but it will be limited to10% more than the displayed distance. In case, source PIN and destination PIN are same, the user can enter up to a maximum of 100 kms only. If PIN entered is incorrect, the system would alert the user as INVALID PIN CODE, but he can continue entering the distance. Such e-waybills having INVALID PIN codes will be flagged for review to the departmental officers. 

2. Blocking of generation of multiple E-Way Bills on one Invoice/document: It has been decided not to allow generation of multiple e-way bills based on one invoice, by any party – consignor, consignee or transporter. That is, once E-way Bill is generated with an invoice number, then none of the parties - consignor, consignee or transporter, can generate another E-Way Bill with the same invoice number.

3. Extension of E-Way Bill in case Consignment is in Transit: The transporters have represented to incorporate provision to extend E-way Bill validity, when goods are in transit. Transit means that goods could be on Road or in a Warehouse. During the extension of validity of the e-way bill, the user will be prompted to answer whether the Consignment is in Transit or in Movement. On selection of In Transit, the address details of the transit place need to be provided by user. On selection of In Movement the systemwill prompt user to enter Place and Vehicle details. For calculation of distance for movement and validity date of an E-way Bill, in both these scenarios, the destination PIN will be considered from the PART-A of the E-way Bill.

4. Blocking of Interstate Transactions for Composition dealers: As per the GST Act, the composition tax payers are not allowed to do Interstate supply. Hence user will not be allowed to generate e-way bill for inter-state movement of goods, if the supplier is a composition tax payer. The composition tax payers will not be allowed to enter any taxes under CGST or SGST for intrastate transactions. Also document type of Tax Invoice will not be enabled for them.
