I don't believe there are any that combine a list of open invoices with the line detail, although you'll find a couple different reports focused on open transactions, and others that focus on line details.
I would suggest creating a report in Power BI (through Power BI Desktop). You'll need to create Web Services in Business Central for the following pages (so we can use them as queries in our dataset in Power BI Desktop, model it, and then publish to PowerBI.com to build your report):
Page 21: Customer Card
Page 25: Customer Ledger Entries
Page 526: Posted Sales Invoice Lines
To model these three together, the No. field on the Customer Card page maps to the Customer No. field on the Customer Ledger Entries page, and the Document No. field on the Customer Ledger Entries page maps to the Document No. field on the Posted Sales Invoice Lines page. And make sure to filter the Customer Ledger Entries page so that you're only getting records of Document Type = Invoice. Potentially, you can also filter the Customer Ledger Entries page to only show records where Open = TRUE.
Then, in either Power BI Desktop, or PowerBI.com, you can build a tabular report showing open Invoices by customer along with Line details.
If you don't want to do it in Power BI, you can also do it in Excel with PowerPivot.
I hope this helps. If my response has answered your question, please verify by clicking Yes next to "Did this answer your question?"
