Hello,
We are encountering a blocking error when processing an inbound notification via the webMethods SAP Adapter (version 10.1 Fix14) on our webMethods Integration Server 10.15.
Most of the time, the SAP notifications are processed successfully without any errors.
However, on a sporadic basis, we encounter the following error in the IS server logs:
"Confirm action for nonexisting Transaction TID"
Last occurrence (server.log) :

When this occurs, the iDoc is not confirmed and remains in the SAP system (transaction SM58)
We have verified that:
- No restart of the Integration Server occurred at the time of the error.
- Network analysis showed no anomalies.
- Connection pool settings on the RFC connection are set to:
- Minimum Pool Size: 1
- Maximum Pool Size: 30
- Listener configuration is:
These settings are identical to other environments where no such issue occurs.
No related errors are visible in SAP system logs.
Thank you in advance for your support,
Best regards,
