How do I enter purchases with quantity which are subject to reverse charge u/s 9(3) e.g. cashew nuts ?

All purchases / inward services which are subject to reverse charge u/s 9(3) should be entered in data form meant for this purpose.

To enable quantity column in this dataform, go to GST Docs -> Purchases / Inward supplies, press F11 to open settings and select “Yes” against the setting “Show quantity column in reverse charge u/s 9(3) data form”.
