The communication issue might be a security restriction on your SAP system:

Security restrictions in SAP:

Your SAP gateway may be set-up not to allow connection from external hosts. This web-page or this web-page gives further explanation, but please check with you basis/security team.

We have developed a small test utility. This will generate a RFC trace file.

You can download our Rfc Test Utility from here.

  1. Unpack the ZIP file in a directory.
  2. Start program RfcTest.
  3. Enter the RFC connection details and click connect.
  4. After about 2 minutes, you should see a trace file dev_rfc.trc or similar created in the same directory. Open this file to see if any connection errors have occurred.

Please send us a copy of the trace file so that we can assist further.

If you do not have the SAP GUI installed, see here and copy the librfc32.dll into the directory there the RfcTest.exe has been extracted into.
