Bill-by Identifier

Hi,

    Could someone throw more light on my below clarifications;

1. If i have 5 lines in the billing staging table for Contracts. Will it create one invoice with 5 line or one invoice with one line, summing up of amounts for all  5 lines?

2. If i have 2 lines in the billing staging table for Contracts. Can we add those 2 lines to the existing invoice id in Billing assuming that invoice is in New or ready status?

 

Regards
