Tool to get dump of books in S/4HANA Cloud for auditing reasons

1 of my customers has been looking for some time to get a dump of their books from S/4HANA Cloud for audit (once a year)

The standard apps can only download to Excel, which has its limitations.

For example, 1 company code has more than 14 million lines.

Can SAP (whether for a fee or not) maintain this through the back end or other tools for them?
