SAP ECC
ECC (SAP ERP Central Component) release notes cover the previous-generation ERP, delivered largely through Enhancement Packages (EHPs). They matter for the large installed base still running ECC.
ECC release notes come with Enhancement Packages, which add optional functionality, and Support Package Stacks, which carry fixes and legal changes, plus switchable business functions that activate new capability. Read the notes before applying either, activate business functions deliberately because some cannot be reversed, and watch ECC's maintenance end dates, which drive the move to S/4HANA.
- Watch out: ECC is in extended maintenance, so a note about a future release may not apply to you at all.
What changes here
- Enhancement Packages (EHPs) deliver optional new functionality.
- Support Package Stacks deliver fixes and legal changes.
- Business Functions (switchable) activate new capabilities.
- End-of-mainstream-maintenance timelines drive the move to S/4HANA.
How to use them
For ECC systems, read EHP and support-package notes before applying them, and activate business functions deliberately (some are irreversible). Above all, note ECC’s maintenance end dates, they are the key driver for planning the move to S/4HANA.
Common pitfalls
- Upgrading without reading the notes.
- Ignoring deprecations.
- Missing compatibility requirements.
