Solutions
3 solutions available1. Verify Adapter Configuration in SAP Gateway Service easy
Check and correct the adapter name in the SAP Gateway service configuration.
1
Access SAP Gateway Service Builder (transaction SEGW).
2
Open the relevant service project that is experiencing the error.
3
Navigate to the 'Service Implementation' tab or equivalent section where adapters are configured.
4
Locate the adapter configuration and carefully review the adapter name. Ensure it exactly matches the expected adapter name (e.g., 'ODATA', 'SOAP', 'RFC', etc.) without any typos, extra spaces, or incorrect capitalization.

If an incorrect adapter name is found, correct it to the valid name and save the changes.
6
Regenerate and deploy the service if prompted.
2. Check RFC Destination Configuration for External Adapters medium
Ensure RFC destinations used by adapters are correctly configured and active.
1
Identify the adapter type that is causing the error. If it's an adapter connecting to an external system (e.g., via RFC, SOAP, or HTTP), you'll need to check the corresponding destination.
2
For RFC adapters, navigate to transaction SM59 in SAP.
3
Search for the RFC destination name that is being used by the failing adapter. The name is often specified in the service configuration or error logs.
4
Select the RFC destination and click the 'Connection Test' button. Verify that the connection is successful.
5
If the connection test fails, review the destination details, including the Program ID, Gateway host, Gateway service, and logon credentials. Ensure they are accurate and that the target system is reachable.
text: Common issues include incorrect Gateway host/service, or the target program not being registered.6
For other adapter types (e.g., HTTP, SOAP), check the corresponding configuration in transaction SM59 (for HTTP) or within the specific adapter framework's configuration tools.
7
Make necessary corrections to the destination configuration and re-test the connection.
3. Review SAP Notes and Component Updates medium
Investigate SAP Notes for known issues related to adapter configurations and ensure relevant components are up-to-date.
1
Access SAP Support Portal (support.sap.com).
2
Search for SAP Notes using keywords like 'ERR_SQL_INV_ADAPTER', 'Invalid adapter name', 'SAP S/4HANA', and the specific adapter technology (e.g., 'OData', 'SOAP adapter').
text: Example search query: "ERR_SQL_INV_ADAPTER S/4HANA OData"3
Analyze the search results for relevant SAP Notes that describe the error and provide solutions or workarounds.
4
Check the 'Software Component' and 'Version' information in the SAP Notes to see if they apply to your S/4HANA system version.
5
If a relevant SAP Note is found, carefully follow the recommended steps, which may involve applying Support Packages, installing specific patches, or making configuration changes.
6
Consider checking for the latest patches or updates for the SAP Gateway component and any relevant integration components (e.g., SAP Cloud Connector if applicable).
