SAP NetWeaver

NetWeaver release notes cover the classic application-server platform underpinning many SAP products (ECC, BW, PI/PO). They cover platform features, support packages and compatibility.

Quick answer

NetWeaver release notes cover the ABAP and Java platform features, support package stacks with fixes and legal changes, and the database, OS and Java compatibility requirements, and they matter for every product built on NetWeaver: ECC, BW and PI/PO. Read the platform notes alongside the application's; S/4HANA's foundation evolved, but the ABAP heritage persists.

Key takeaways
  • Watch out: the kernel and the support package stack move independently and each has prerequisites.

What changes here

  • ABAP/Java platform features and enhancements.
  • Support Package Stacks with fixes and legal changes.
  • Compatibility (database, OS, Java) requirements.
  • Relevance to products built on NetWeaver (ECC, BW, PI/PO).

How to use them

For NetWeaver-based products, read the platform release/support-package notes alongside the application’s. Although S/4HANA uses an evolved foundation, the NetWeaver ABAP heritage persists, so its notes remain relevant to many existing systems.

Common pitfalls

  • Upgrading without reading the notes.
  • Ignoring deprecations.
  • Missing compatibility requirements.
