E-way bill for intra state --- reg : invoice date

Example:  Actual Gst Invoice No. 1 Dated 20/1/18 at 7.00 AM .. Own Vehicle and Distance 50 KM --- For INTRA STATE

FOR Avoiding any disturbance or hand to mouth time limitation ... Need to Generate E-Way Bill before 12 hrs.

Like : E-Way Bill Date 19/1/18 at 6.00 PM and GST Invoice Date 19/1/18 (Actual GST Invoice Date 20/1/18)

Because No Option To Select Next Date of GST Invoice in E-Way Bill Portal .....

So, Actual Removal Date is 20/1/18 and GST Invoice Date Also 20/1/18 .. But Forcefullly I have to Select date 19/1/18

Please give suggestions ;;;;;;
