Invoice reversal for a invoice doc having no posting rel line item

Hi Experts,

I have one Invoice have zero amount or no line item relevant for posting, so the moment this invoice is posting it is clearing with its own doc no.

Now when I try to reverse this using EA15 it gives error saying "Doc have clearing doc" and when I try to reset clearing it gives error "Doc type is not a clearing doc".

Now how to reverse such invoices.

Regards

Manoj
