Table link from production order to operations using variant configuration

Hi all,

I'm trying to mine down from the production order down to the operations and work centers assigned.

I'm familiar with the usual method "AUFK-OBJNR to link to AFVC-OBJNR then use AFVC-OBJID to link to CRHD-OBJID"

However the client I'm at uses variant configuration and the Object number in AUFK is different in AFVC. Does anyone know how the data links up when VC is used?

Mark.
