KONV-KNUMV updated after VBOF?

Hi Experts,

I would like to know how table KONV is updated if i have a billing document with certain KNUMV, and then after running VBOF to update a billing document, a new accounting document is created.

My understanding is that same KNUMV is updated. Is there any way to check how KONV is updated after updating the billing document in VBOF? I mean, the condition before and after.

Thanks in advance,

Pablo
