We have many invoices lying in our warehouse against which we have to deliver material to our customers but due to lock-down enforcement physical delivery is not possible.

Kindly suggest if we could be able to deliver material post lock-down (hopefully after 15th April) against same invoices by generating eway bill then. In other words can we generate eway bill for 1 month old invoice?
