Reporting Currency Error

Hi,

While Invoicing Purchase Order we are not able to post we are getting error “reporting currency and invoice currency is not matching”

So request you to suggest me what can be done remove this error while posting invoice Purchase Order

I found where was the problem.

I did select a posting profile in AP Parameter> Ledger & Sales Tax> Posting > Posting Profile. But i didn’t setup the vendor posting profile properly.
After do setup it now i can post invoice ready.
