SAP S/4HANA Error 586: Invalid API Parameter Received
Description
This error indicates that an SAP S/4HANA API call or integration received data from a connected server that does not conform to the expected format, type, or value. It typically occurs when there's a mismatch in data structures or mandatory fields between systems attempting to communicate.
Error Message
ERR_API_INV_PARAMETER_FROM_SERVER
Known Causes
4 known causesData Type Mismatch
The parameter sent by the server has a different data type than what SAP S/4HANA expects (e.g., a string was received instead of an integer).
Missing Required Parameter
A mandatory parameter expected by SAP S/4HANA was not included in the server's response or was empty.
Incorrect Parameter Value/Format
The value of a parameter received from the server does not adhere to the expected format or falls outside the permissible range.
API Version Incompatibility
The server is using an older or newer API version that sends parameters not recognized or expected by the current SAP S/4HANA configuration.
Solutions
4 solutions available1. Verify API Endpoint and Payload Structure medium
Ensures the API call is directed to the correct S/4HANA endpoint with a valid data structure.
1
Identify the specific API being called that is triggering the error. This might be a custom API or a standard SAP API.
2
Consult the SAP S/4HANA API documentation for the identified API. Pay close attention to the expected request method (GET, POST, PUT, DELETE), the URL endpoint, and the required request payload structure (e.g., JSON, XML).
3
Compare the actual API request being sent by the client application with the documented requirements. Specifically, check for:
- Correct URL path and query parameters.
- Valid HTTP method.
- Properly formatted request body (e.g., JSON keys and data types, XML elements and attributes).
- Correct URL path and query parameters.
- Valid HTTP method.
- Properly formatted request body (e.g., JSON keys and data types, XML elements and attributes).
4
If using a tool like Postman or SAP API Business Hub, re-create the request with the correct parameters and payload structure to confirm it works. For programmatic calls, review the client-side code responsible for constructing the API request.
2. Check SAP Gateway (OData Service) Configuration medium
Validates that the OData service exposed by S/4HANA is correctly registered and configured.
1
Log in to your SAP S/4HANA system using transaction code `SEGW` (Gateway Service Builder) or `SRT_ADMIN` for SOAP services.
2
Search for the relevant OData service (or SOAP service) associated with the API call. Verify its existence and active status.
3
Navigate to the service's properties and check the 'Service Implementation' or 'Runtime' settings. Ensure the correct classes are assigned for processing requests.
4
In transaction `SICF`, ensure the ICF node corresponding to the OData service is active and correctly configured for the relevant HTTP method.
5
If the service is custom, review the ABAP code within the service implementation classes to ensure it correctly handles incoming parameters and constructs the response.
3. Review SAP S/4HANA System Logs and Traces easy
Analyzes system logs for more detailed error information from the S/4HANA server.
1
Access the SAP Gateway Error Log using transaction code `SMGW` and navigate to 'GoTo' -> 'Error Log'.
2
Alternatively, use transaction `ST22` to check for ABAP dumps that might have occurred during the API processing. Look for dumps related to the time the error occurred.
3
For deeper analysis, enable Gateway tracing. In `SMGW`, go to 'Goto' -> 'Trace' -> 'Switch On'. Reproduce the error and then turn off tracing and download the trace file for review.
4
Examine the error log and trace files for specific messages indicating which parameter was deemed invalid and why. This might reveal missing fields, incorrect data types, or unexpected values.
4. Validate Data Types and Constraints in Backend advanced
Ensures that the data sent in the API request conforms to the data types and constraints defined in the S/4HANA backend.
1
Using transaction `SE11` or `SE16N`, inspect the relevant database tables or structures that the API is interacting with. Identify the data types (e.g., CHAR, NUMC, DEC, TIMESTAMP) and length constraints for the fields expected by the API.
2
If the API is a custom OData service, review the data elements and domain definitions in ABAP. Ensure that the data types and value ranges defined in the ABAP code match the expectations.
3
Check for any custom validation logic implemented in the backend (e.g., in BAdIs, enhancement spots, or the OData service's DPC_EXT class) that might be rejecting the parameter due to business rules or data integrity checks.
4
If a specific parameter value is causing the issue, try sending a valid, known-good value for that parameter to isolate the problem.
