What does this error mean when billing in suitebilling? You cannot edit charge lines on invoices, cash sales, credit memos, or cash refunds.

AI generated answer (using internal Slack threads):

The error message "You cannot edit charge lines on invoices, cash sales, credit memos, or cash refunds" typically appears when there is an attempt to modify the charge lines on certain transaction types in NetSuite, specifically invoices, cash sales, credit memos, or cash refunds. This is a built-in restriction in NetSuite's SuiteBilling module to ensure the integrity of the billing data. In the context of the conversations provided, it seems that the error is being triggered during the billing process of a Charge Based Project. The charges are generated correctly and appear on the invoice, but the error occurs when trying to save the invoice. This could be due to a misconfiguration in the billing process or a conflict with other workflows or scripts. One suggestion from the conversation is to use the "Process Billing Operations" function instead of "Bill Sales Orders" if Sales Orders are not being used. This could potentially bypass the issue. Another conversation suggests that the error might be due to a bug in one of the sublists that is due to post sourcing of the header level item. This causes the item sublist to select a new line thinking something is going to be entered. A workaround suggested is to add a client script to grab the line and cancel it. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
