SAP uses native libraries which you should get from webMethods Support or SAP (if not included with the adapter). You need to place these libraries in the <is>/lib folder and the IS will pick them up.

Jordy, thank you for your reply. I found the following note in the SAP BC Installation Guide: “if you get errors while the Server is loading the SAP package, check if the versions of MSVCRT.dll and MSVCP60.dll in C:\WINNT\system32 are older than the ones in <sapbc>\Server\packages\sap\code\libs. If yes, copy the newer ones into C:\WINNT\system32 (using a DOS prompt) and reboot the system. Also check if there are still old versions of these dll’s somewhere on the hard drive: Librfc32.dll, jRFC11.dll, jRFC12.dll.”
I found that there was no MSVCP60.dll in C:\WINNT\system23 so I copied it from <sapbc>\Server\packages\sap\code\libs, along with Librfc32.dll, jRFC11.dll, jRFC12.dll and rebooted the server. Problem solved.
Thanks again.
