Controling AFVC table with WF

HI guys,

I created a workflow to control creation, modification and deletion records on AFVC table, (not status changed), but this WF is started from other event when CJ20N modify a position from a Purchase Requsition and the event is given from Purchace Requisition Object After modifying a network on CJ20N.

the problem is that i need to recognice in AFVC the record affected and I was trying to mach the tables CDHDR with AFVC, but AFVC doe not have the time on its records, so I am not able to know the right record in AFVC.

any help?

Thanks a lot.
