Dear ABAP Consultants,
I'm wondering which function used to create an ABAP multi level hierarchical report like example below :
| level 1 | Company Code | invoices from 1 to 30 days | invoices from 30 to 60 days | invoices more than 60 day |
| level 2 | Vendor | sum of vend. invoices | sum of vend. invoices | sum of vend. inv. |
| level 3 | Invoices | Invoice number | Invoice number | Invoice number |
Any answer will be appreciated.
Thank you in advance
