The link shared by Avik is for Adapter Connection/Service. Since you have trouble with a Listener Notification, here are my comments, on top of what @rmg has shared -
- Is your Listener is enabled successfully and is the SAP Adapter package fully loaded?
- Often, a refresh of the Listener and the Listener Notification resolves any transient issues
- [Important] Does the configured user have adequate authorization on the SAP side?
- What’s your wM (or SAP Adapter) version?
- What type of Notification (Sync/Async) have you configured?
- If Async, is your DocType publishable, and is your Subscriber able to fetch it from your Messaging subsystem (Broker/UM/IS)? Perform a local publish test to see if this works.
- Try enabling trace (for RFC Listener) and see if there are any issues in the logs
- You can test the RFC Listener from IS and check the status in SAP
There’s a lot of valuable info in the documentation (link); give it a read.
