Re: Installation of a Dialog Instance (DI)

Hi Steffen,

Please see below comment

2.3 Can I install my SAP system as a non-Unicode system?

You can install an SAP NetWeaver 7.0 SR1 or SR2 ABAP system as a non-Unicode system. When you install an SAP NetWeaver 7.0 SR1 or SR2 dual-stack system (ABAP+Java), the ABAP part of this system can also be installed as non-Unicode, while the Java part can only be installed as Unicode.
As of SAP NetWeaver 7.0 SR3, you cannot install an SAP NetWeaver ABAP system or the ABAP part of an SAP NetWeaver dual-stack system as non-Unicode any longer. However, non-Unicode is still supported when you perform the system copy of an SAP system upgraded to SAP NetWeaver 7.0 SR3.
