SAP Connection Error

Problem: When you attempt to connect to an SAP server from the Visual Studio development environment, you may see Open file C:\WINDOWS\sapmsg.ini failed, which indicates that the file is missing, and you cannot connect to the SAP system.

Solution: Add sapmsg.ini to your Visual Studio environment:

  1. In C:\WINDOWS\, use a text editor to create a file called sapmsg.ini file, and insert this line:

    <SAP_System_Number>=<IP_Address>

    Where:
    • SAP_System_Number is the value of the SAP system number connection property (jco.client.sysnr), and
    • IP_Address is the IP address of the Unwired Platform machine.
  2. Using a text editor, open C:\WINDOWS\system32\drivers\etc\services, and add a service that has this format:

    sapms<SAP_System_Number> <Message_Server_Port>\tcp

    For example:

    sapmsC27 3602\tcp

  3. Restart the system.
  4. Verify that group public is enabled for the SAP application. See your SAP documentation.
