Hello Vladimir,
you can assume that there will be a similar conversion path from SAP Simple Finance, on-premise edition 1503 to the then current 2016 version of SAP S/4HANA on-premise edition. As well you can assume that there will be similar automated data migration functionality where requried.
There are things different between SAP Simple Finance, on-premise edition 1503 and SAP S/4HANA on-premise edition 1511 (and then the following releases). These differences are listed in the SImplification List in dedicated Simplification Items. For example:
- In the master data area, there is the Business Partner approach mandatory (for details see appropriate Simplification Item).
- The Material Number will be extended from 18 to 40 Char (after a system conversion the default remains with 18 Char - customer can decide at which point in time he uses 40 Char) - more details see Simplification Item
Kind Regards,
Frank
