SAP Libraries

To use ERPConnect you need also the following SAP libraries.
You can find the SAP Libraries in the SAP Marketplace download area.

Netweaver RFC Library

ERPConnect supports the Netweaver RFC (SDK) as of version 4.6.0.
Download the Netweaver library from the SAP Software Download Center. For 64-Bit environments the following DLLs are required (XX can vary depending on the version of the NW RRC Libraries):

• sapnwrfc.dll
• icuucXX.dll
• icudtXX.dll
• icuinXX.dll

Copy the 64-Bit Version of NW Libraries to the C:\Windows\System32 folder.
Copy the 32-Bit Version of NW Libraries to the C:\Windows\SysWoW64 folder.

If no protocol is defined when opening an SAP connection, the connection uses the Netweaver RFC library by default.

Client Protocol RFC (librfc32.dll)

Copy the 64-bit version of librfc32.dll to the C:\Windows\System32 folder.
Copy the 32-Bit Version of librfc32.dll to the C:\Windows\SysWoW64 folder.

Note that the files have the same file name, only the file size varies.

To use the Classic RFC Protocol, set the Property Protocol of the R3Connection object to ClientProtocol.RFC before you open the connection.

R3Connection.Protocol = ClientProtocol.RFC;
