CVD indicator ticked in excise invoice..

Dear All,

In one of my domestic excise invoice CVD indicator gets ticked (in miscellaneous tab of J1IEX) so entry was displayed as "Bill of entry" in J2I9 report.

But actually this was not import related procurement also we have not maintained any Countervailing duties in Purchase order.

Second thing for same PO another line item entry (which is having different excise invoice no) is correct. No CVD indicator is ticked in that case.

How this can happen for one Purchase order itself.

Please let me know how it is picked up and what was wrong in that

Thanks,

Naren
