Cannot create Invoice price variance in AP

Hi,

Iam trying to create price variance in AP by following the below steps:

-Enter manual invoice with header amount slightly higher/lower than the PO amount and match the invoice to PO.

-When i save the invoice and do validation,it goes on Dist Variance hold which is a system hold and cannot be released without correcting the condition.

If i correct the condition,there wont be any variance . Since iam trying to create variance on purpose in AP so that this can appear in IPV report,iam wondering how do i do that.

Can anybody please suggest how to create IPV in AP so that it can appear in IPV report?
