You need to determine the tables, views, or calculation views that the Z-report accesses and use the SAP HANA connector to extract data directly from these tables or views.
If you have knowledge with SAP Data Services, you can extract data from SAP ECC and load it into ADLS Gen2 (you can face some increase in the costs if you need to handle non-SAP sources separately).

I found this also (but I am not familiar with it) Theobald's Xtract Universal, you can integrated it with ADF to trigger and automate SAP data movements using command-line interfaces.
