I am using SuiteBilling. I am getting this failure message when trying to bill some subscriptions billing accounts through the Billing Operations Process - "You cannot edit charge lines on invoices, cash sales, credit memos, or cash refunds". The strange thing is I can go to the Billing Account and select the Next Bill button and it will generate an invoice for the NBCD. It just need to generate these invoices through the billing operations process so it can schedule the Billing Operation and auto invoice. Does anyone have possible reasons for why this failure message is a happening.
