Input tax credit as on 30-06-2017

My client has got input tax credit as on 30-06-2017 and has filed his returns (last 6 months) as stipulated in Section 140 of the GST Act and hence eligible to set off the credit against the GST liablility.

But the form GSTR3B doesnot have the provision for this. Nor the electronic ledger doesnot show the balance carried over from the VAT/Central Excise regime.

Any guidelines?
