  • What is the cause and solution for SAP error message SALV_X_API160 - Hash algorithm &1 is not supported for signing ?

    The SAP error message SALV_X_API160 indicates that the hash algorithm specified for signing is not supported. This error typically arises in the context of digital signatures or cryptographic operations within SAP systems, particularly when using the SAP ALV (ABAP List Viewer) framework or when dealing with secure communications.

    Cause:

    1. Unsupported Hash Algorithm: The hash algorithm specified in the configuration or code is not recognized or supported by the SAP system. This could be due to using an outdated or deprecated algorithm.
    2. Configuration Issues: The system may not be properly configured to support the required cryptographic algorithms, or the necessary libraries may not be installed.
    3. Version Compatibility: The version of the SAP system or the underlying libraries may not support the specified hash algorithm.

    Solution:

    1. Check Supported Algorithms: Verify the list of supported hash algorithms in your SAP system. You can do this by checking the relevant SAP documentation or using transaction codes like SE11 to look at the relevant tables or structures.
    2. Update Configuration: If you are using a custom implementation, ensure that the hash algorithm specified in your code is one of the supported algorithms. Commonly supported algorithms include SHA-256, SHA-1, etc.
    3. Upgrade SAP System: If the hash algorithm is required for compliance or security reasons, consider upgrading your SAP system to a version that supports the desired algorithm.
    4. Consult SAP Notes: Check for any relevant SAP Notes that might address this issue. SAP frequently releases notes that provide fixes or workarounds for known issues.
    5. Contact SAP Support: If the issue persists, consider reaching out to SAP support for assistance. They can provide guidance based on your specific system configuration and requirements.

    Related Information:

    • SAP Documentation: Review the official SAP documentation for cryptographic functions and supported algorithms.
    • Security Guidelines: Familiarize yourself with SAP's security guidelines, which may provide insights into best practices for implementing digital signatures and cryptographic operations.
    • Transaction Codes: Use transaction codes like SE80 (Object Navigator) or SE37 (Function Module) to explore the relevant function modules that may be involved in the signing process.

    By addressing the above points, you should be able to resolve the SALV_X_API160 error and ensure that your SAP system can successfully perform the required signing operations.
