SAP NetWeaver RFC SDK (New) 

SAP NetWeaver RFC SDK provides a new API and sample programs that C and C++ programmers can use to integrate their applications with the SAP ABAP application server using the RFC protocol.

Use

SAP NetWeaver RFC SDK is an alternative to “ASCII” and “Unicode” in the classic RFC SDK.

SAP NetWeaver RFC SDK supports a revised API that is based on the usability aspects of SAP Java Connector. It offers the following advantages:

·   Complete yet minimal API.

·   API for metadata repository for dynamic metadata procurement.

·   Supports all SAP individual code pages

·   Dynamic selection between the classic RFC protocol and the new binary protocol that handles all interface data types in the same way.

SAP NetWeaver RFC SDK can be used with all currently maintained SAP systems.

SAP NetWeaver RFC SDK and the classic RFC SDK are not interchangeable, as their APIs are incompatible. The application developer has to actively convert the relevant C or C++ application to the new API.

Note:

If you use the classic RFC SDK (ASCII or Unicode version), a migration to the new version is recommended as the classic APIs are no longer supported for NetWeaver versions 7.1x.

Also note the SAP Note 1005832 on the different RFC SDK versions.
