Duplicate invoice check against FI parked invoice

Hi! Can I find out whether it is possible to do duplicate LIV invoice check against a parked FI invoice? This will happen in situation where the invoice was first created as a FI invoice without a PO and then when the information is clearer, a LIV invoice was created. Current testing in the system shows that there is no check.

Note that the duplicate check works the other way round, I.e. if a LIV invoice is parked and then a FI invoice is created, a duplicate check happens without problem.

Appreciate clarification on the above.

Cheers!
