Say NW 7.4 to 7.5 (Basis 740 to 750)
Say NW 7.57 to 7.58 (Basis 757 to 758)
Most of the Projects have ERP, S4HANA System by default. All Projects would have been experienced a scenario where they want to upgrade NW to higher version alone without touching other component.
Major Example:
To do Custom ATC Check - For S4HANA Conversation and Readiness Check which usually compatible only from NW 7.52 (Basis 752) onwards
This is just to reiterate basic concept of Installation behaviour.
ERP EHP, S4HANA System comes with corresponding NW/ABAP Platform Component version for each explicit version as a default Installation Landscape and Behavior.
Example:
Both ERP EHP and NetWeaver System will be dependent to each other for explicit versions
EHP6 for ERP6.0 can only have SAP EHP3 FOR SAP NETWEAVER 7.0 (SP update possible SP23 onwards)
EHP 7 for ERP6.0 can only have SAP NetWeaver 7.4 Basis 740 (SP update possible)
EHP 8 for ERP6.0 can only have SAP NetWeaver 7.5 Basis 750 (SP update possible)
✨We can't upgrade NW Package alone without EHP - Say EHP7 on NW 7.5 or higher
Only way - We can update to EHP8 which automatically includes NW 7.5 Version"
Same scenario applies to all versions including S4HANA - Say ABAP Platform 2023 - Basis 758 - for S/4HANA 2023 only.
Most of the Project members/Clients got confused by seeing PAM - Say for example - EHP6 for ERP 6.0 - Required Product Versions. Those details were provided(included) w.r.t Upgrade To versions as well. Hence, It will include all versions leading to the confusion.
If we have Standalone Separate NW System any version including SAP EHP3 for SAP NW 7.0 without ERP EHP then then we can upgrade NW. Its possible in general.
Say - from Standalone EHP3 For SAP NW 7.0 to Standalone NW 7.4 or 7.5.
Refer below note for reference.
