How to find Fi documentument is reversed or not .

Hi

How do we know the document is revered or not using transaction FBR2?

1) If new document is creates using transaction code F-02... then BKPF will creates the new document with Doc type is "AC"

2) If above document is reversed using transaction code FBR2.... then table BKPF will creates new document with doc type "AD".

But How would we knows Document type "AC "is reversed or not? Is there any field will update for this doc is reversed or not in Table BKPF
