Third Party Orders not appearing in billing due list. Item Cat billing rel 'F' & VTFA Billing Qty E

Question

I had a requirement to do my customer billing for third party scenario before doing the invoice verification.
The solution that was proposed was to make the following changes,
In VOV7 (For TAS )item category the billing relevance should be (G) and
in the copy control VTFA  at item level  for item cat (TAS)maintain the billing qty(E).

The problem I faced with the above config change was that nothing was appearing in the billing due list and when I tried to do a billing from the order directly, it would not let me.
Then I made the following change,
In VOV7 (For TAS )item category the billing relevance as (F) and
in the copy control VTFA  at item level  for item cat (TAS)maintained the billing qty(E).
Now after the MIGO is done based on the PO, the system allows me to do a customer billing from the SO before the invoice verification. But still this SO is still not appearing in the billing due list. Have any of you experts faced the same problem? How can I get this to appear in the billing due list? Or in other words, how do I identify open third party sales orders that are due for billing?
Thanks and regards

Answer 1

@ Joan, in that case invoice verification would now be necessary anymore right? In my case i need the invoice verification to happen...but at a later stage
With the existing config...i.e. F as billing relevance and E as billing quantity, I now tried doing a MIRO immediately after the MIGO and then it appears in the billing due list. So basically I think its the billing relevance F...and if I want it to come in VFO4 before MIRO, perhaps a tweak in the logic of VFO4 to include billing relevance F + billing quantity E ?
