On October 7, 2020, SAP launched the new and thus sixth on-premise release 2020. With the new release, SAP changes the release nomenclature from 1709, 1809 and 1909 (YYMM) to 2020 (YYYY).
SAP S/4HANA 2020 includes 1,269 major and minor changes.
For a S/4HANA migration the Simplification List is an indispensable tool for checking whether custom code and modifications still work with S/4HANA, whether transactions used in SAP ECC can still be used (or have been combined/simplified and can now be used with a Fiori app), whether transaction codes have changed, whether something is no longer supported, or whether something has been simplified and replaced by completely new possibilities.
