India - VAT Invoice Generation / Accounting

Hi,

India - VAT Invoice Generation / Accounting program completed with error and showing below error message

Delivery - xxxxx Cannot be processed because all delivery details are not inventory interface

I found note - on metalink - 1144603.1

SELECT 1
FROM
wsh_delivery_details wdd ,
wsh_new_deliveries wnd ,
wsh_delivery_assignments wda
WHERE
wdd.delivery_detail_id = wda.delivery_detail_id AND
wda.Delivery_Id = wnd.Delivery_Id AND
wnd.Delivery_Id = :cp_delivery_id AND
wdd.source_code = 'OE' AND
NVL(wdd.inv_interfaced_flag,'N') <> 'Y'

Above query returns rows.

As per above note, need to resolve interfacing issue. I would like know how to resolve interfacing issue. Please suggest.
