You'll need to provide a lot more information for anyone to be able to help you.
Show your scripts that you are using to attempt to communicate with SAP. What do the payloads you are sending to Ignition look like? Provide examples of your attempts (with sensitive information redacted as necessary). Are there any errors in your gateway logs that line up with failed attempts?
Post code and payloads as preformatted text to aid with viewing and troubleshooting, see Wiki - how to post code on this forum.
