Hi KS,
Firstly, the billing documents that you want to combine within an Invoice List must already have been billed and released to accounting. Then when you save the invoice list, the system automatically creates an accounting document for the factoring conditions you have in your pricing procedure for Invoice List.
Now, to validate your pricing and accounting configuration in your Invoice List billing doc type (TCode VOFA), please check the following fields:
- AcctDetermProc.
- Doc. pric. procedure
I hope they are maintained. If not, maintain them and revisit your pricing/accounting determination again.
Else if they are there, then make sure the pricing procedure getting determined for Invoice List. And that pricing procedure, you have accounting key against each relevant condition type in use. Further, make sure you have proper accounting determination is maintained and determined.
Also, refer SAP Note 110444 - Invoice list condition not in account-based CO-PA
Thanks, JP
