Header Billing Plan - credit memo and debit memo

Folks,

I have the following scenario here.

I have a billing plan order (BP) - with header billing plan.

I have three lines in the billing plan

1) $5000 ...FAZ (Billing Request)

2) $10000...L2 (Debit Memo)

3) $3000...G2 (Credit Memo).

Once i go to VF04,

I have all three billing due. However, only billing type FAZ has the header conditions (PR00, AZWR, TAXES) populated and net value $5000. (Populated against AZWR)

Both L2 and G2 have no header conditions populated and the net value is 0.

The copy control is set up the same for all and all have same document pricing procedure (A).

Is it something basic I'm missing or is there anything else I have to do?

Or pls let me know the process for debit memo / credit memo with a billing plan.

Pls respond ASAP as we have the Proof of Concept scheduled sooner.

Helpful answers will be rewarded promptly!

Thank You,
