  • What is the cause and solution for SAP error message SWDP_WB_TOOL653 - Different controller type for &/& ?

    The SAP error message SWDP_WB_TOOL653, which states "Different controller type for &/&," typically occurs in the context of SAP Web Dynpro applications. This error indicates that there is a mismatch in the controller types being used in the application. Here’s a breakdown of the cause, potential solutions, and related information:

    Cause:

    1. Controller Type Mismatch: The error usually arises when there is an inconsistency between the controller types defined in the Web Dynpro component and those expected by the application. This can happen if:

      • The component has been modified, and the controller types have not been updated accordingly.
      • There are multiple versions of the same component, and the wrong version is being referenced.
      • There are inconsistencies in the configuration of the Web Dynpro application.
    2. Incorrect Configuration: If the configuration settings for the Web Dynpro application do not match the expected settings for the controllers, this error can occur.

    Solution:

    1. Check Controller Definitions:

      • Go to the Web Dynpro component in the SAP development environment (SE80).
      • Verify that the controller types defined in the component match the expected types. Ensure that the controller is correctly defined and that there are no discrepancies.
    2. Rebuild the Application:

      • Sometimes, simply rebuilding the Web Dynpro application can resolve the issue. This can be done by activating the component again in the development environment.
    3. Check for Version Conflicts:

      • Ensure that you are using the correct version of the Web Dynpro component. If there are multiple versions, make sure that the application is referencing the correct one.
    4. Review Application Configuration:

      • Check the configuration settings of the Web Dynpro application to ensure that they are correctly set up. This includes checking the application parameters and any associated settings.
    5. Clear Cache:

      • Clear the cache of the Web Dynpro application. Sometimes, cached data can lead to inconsistencies. You can do this by using transaction code SICF to refresh the service.
    6. Check for Dependencies:

      • Ensure that all dependencies for the Web Dynpro component are correctly defined and activated. Missing dependencies can lead to controller type mismatches.
