Description
This error, ERR_SQL_INV_AGENT_PROPS, indicates a problem with the configuration or properties of an agent within the SAP S/4HANA system, specifically related to SQL operations. It typically occurs when a background job, service, or integration component relies on an agent with incorrectly defined or missing properties, preventing it from executing its intended tasks.
Error Message
ERR_SQL_INV_AGENT_PROPS
Known Causes
3 known causesMisconfigured Agent Parameters
Essential parameters for the agent, such as connection strings, credentials, or execution paths, are incorrectly set or missing in its configuration. ⚙
Insufficient Permissions
The user account or system process running the agent lacks the necessary database or system-level permissions to access or modify required resources. 🔒
Corrupted Configuration Data
The configuration file or database entry storing the agent's properties has become corrupted or contains syntax errors, making it unreadable or invalid. 💻
Solutions
3 solutions available1. Verify Agent Configuration in SAP Gateway Service medium
Ensures the SAP Gateway service correctly defines the properties for the agent involved in the communication.
1
Log in to your SAP S/4HANA system using a user with appropriate authorizations (e.g., SAP_ALL, SAP_NEW or specific roles for Gateway configuration).
2
Navigate to transaction code SMGW (Gateway Monitor).
3
From the Gateway Monitor menu, select 'Goto' -> 'Expert Functions' -> 'External Security'.
4
In the 'External Security' screen, locate the entry corresponding to the agent that is causing the error. This might involve checking the 'Program ID' or 'Gateway Host' if the agent is an external program.
5
Review the 'Properties' for this agent. Ensure that all required properties are correctly set, and there are no typos or invalid values. Common issues include incorrect hostnames, ports, or security settings. If you are unsure about the correct properties, consult the documentation for the specific agent or the SAP Note related to this error.
6
If any properties are incorrect, modify them and save the changes. You may need to restart the Gateway service or the affected agent for the changes to take effect.
2. Check and Correct RFC Destination Configuration medium
Validates that the RFC destination pointing to the agent has accurate and compatible settings.
1
Log in to your SAP S/4HANA system with administrative privileges.
2
Navigate to transaction code SM59 (RFC Destinations).
3
Locate the RFC destination that is being used to communicate with the agent experiencing the ERR_SQL_INV_AGENT_PROPS error. This destination might be of type 'T' (TCP/IP) or 'G' (Registered Server Program).
4
Double-click on the RFC destination to edit it.
5
Under the 'Technical Settings' tab, verify the following:
6
- **Target Host:** Ensure it's the correct hostname or IP address of the agent's server.
7
- **Gateway Host:** If applicable, confirm it's the correct Gateway host.
8
- **Gateway Service:** Verify the correct Gateway service name or port.
9
- **Program ID:** For registered server programs, ensure the Program ID exactly matches the one registered in the SAP Gateway.
10
Under the 'Security Options' tab (if applicable), review any security settings, such as SNC (Secure Network Communications) parameters, to ensure they are correctly configured and compatible with the agent.
11
Save the changes made to the RFC destination.
12
Test the RFC connection by clicking the 'Connection Test' button. Address any new errors that appear during the test.
3. Review SAP Notes and System Patch Level advanced
Identifies and applies relevant SAP Notes or system updates that address known issues with agent property handling.
1
Access the SAP Support Portal (support.sap.com) and search for SAP Notes related to 'ERR_SQL_INV_AGENT_PROPS' or 'Error 509 SAP S/4HANA'.
2
Pay close attention to notes that mention agent property validation, RFC communication, or specific components involved in the failing process.
3
Check the prerequisites for each relevant SAP Note, including the specific S/4HANA version and Support Package stack you are running.
4
If a relevant SAP Note is found and your system does not have it implemented, plan and execute the implementation of the note following SAP's standard procedures. This may involve using transaction SNOTE.
5
Alternatively, investigate if your current system patch level is up-to-date. Sometimes, this error is a symptom of a known bug that has been fixed in a later Support Package or Enhancement Package. Consider planning for a system upgrade or applying the latest available patches if you are significantly behind.
6
After implementing SAP Notes or applying patches, restart the affected SAP instance or the specific Gateway service if necessary, and re-test the functionality.
