Change Document Object for Billing: Header Data (VBRK)

[Bibby, David]

Hello,
I was wondering if anyone could help me.
I have a request for  workflow to be be triggered by an insert on table VBRK
where the insert is for a specific billing type e.g. reversal or credit
note.
When this happens I need to check if any payments have been made against the
bill that is being reversed or credited.
 
I have been looking in SWEC for an appropriate Change Document Object but
cannot find one.
Has anyone ever done this in the past as I need to trigger the workflow on
an insert to VBRK (Billing: Header Data) ?
 
Thanks
David
