Hi Pascal,
I have double checked this and it finally appears that SAP 3.2 SP3 is now certified on Red Hat Enterprise Linux 6/7. The documentation will be updated accordingly.
For Red Hat Enterprise Linux 7, you need to use the SAP RFC SDK 7.20 library included in package
RFC_13-10009516.
You will need to pull down this package for the “LINUX ON IA32 32BIT” platform. It indicates Itanium but you will find it is actually for x86.
I hope this helps
Best Regards
Guy
