  • What is the cause and solution for SAP error message WEBDYNPRO_RT020 - You are not authorized to start Web Dynpro application configuration & ?

    SAP Error Message:
    WEBDYNPRO_RT020 You are not authorized to start Web Dynpro application configuration &


    Cause:

    This error occurs because the user attempting to start or configure a Web Dynpro application does not have the necessary authorizations. Specifically, the user lacks the required authorization objects or roles that permit access to Web Dynpro application configuration or runtime activities.


    Explanation:

    • Web Dynpro applications often require specific authorizations to be started or configured.
    • The error message indicates that the user is missing authorization to perform the action.
    • The placeholder & in the message usually contains the name of the application or configuration that the user tried to access.

    Common Authorization Objects Involved:

    • S_WDY_APPL: Authorization for Web Dynpro applications.
    • S_WDY_CONF: Authorization for Web Dynpro configuration.
    • S_RFC: If the Web Dynpro application calls RFCs, relevant RFC authorizations may be needed.
    • S_SERVICE: For services related to Web Dynpro.

    Solution:

    1. Identify the missing authorization:

      • Check the exact application or configuration name from the error message.
      • Use transaction SU53 immediately after the error occurs to see which authorization check failed.
      • Alternatively, check the system log or developer trace for authorization failures.
    2. Assign the required roles/authorizations:

      • Assign the user the appropriate roles that include the necessary authorization objects.
      • For Web Dynpro application configuration, roles typically include:
        • Authorization for S_WDY_APPL with the relevant application name.
        • Authorization for S_WDY_CONF if configuration changes are needed.
      • If unsure, consult your security team or BASIS administrator to create or assign the correct roles.
    3. Test the access:

      • After role assignment, have the user log off and log back in.
      • Retry starting or configuring the Web Dynpro application.
    4. If you are an administrator:

      • You can test with a user that has full authorizations (e.g., SAP_ALL) to confirm the issue is authorization-related.

    Additional Information:

    • Web Dynpro applications are UI components in SAP that require specific runtime and configuration permissions.
    • Authorization checks are strict to prevent unauthorized access or changes to application configurations.
    • Always follow your organization's security policies when assigning roles.
    • For development or troubleshooting, use SU53 and ST01 (trace) to analyze authorization failures.

    Summary:

    Aspect Details
    Cause User lacks authorization to start/configure the Web Dynpro application.
    Solution Assign appropriate roles/authorizations (e.g., S_WDY_APPL, S_WDY_CONF) to the user.
    Check Tools Use SU53 after error, system logs, or ST01 trace to identify missing authorizations.
    Notes Ensure roles comply with security policies; test with authorized users if needed.

    If you need help identifying the exact roles or authorization objects, please provide the Web Dynpro application name or the output of SU53 after the error.
