  • What is the cause and solution for SAP error message WXP737 - Unexpected return code in FB REUSE_ALV_POPUP_TO_SELEC ?

    Certainly! Here's a detailed explanation for the SAP error message:


    SAP Error Message:

    WXP737 - Unexpected return code in FB REUSE_ALV_POPUP_TO_SELEC


    Cause:

    The error WXP737 occurs when the function module REUSE_ALV_POPUP_TO_SELECT (or its newer equivalent REUSE_ALV_POPUP_TO_SELECT) returns an unexpected return code. This usually happens because:

    • The ALV popup selection screen was canceled by the user (e.g., pressing Cancel or Back).
    • The function module returned a non-zero return code indicating an abnormal termination or user abort.
    • The calling program or report does not handle the return code properly.
    • There might be inconsistencies or errors in the parameters passed to the ALV popup function module.
    • Sometimes, the error can occur if the ALV grid or container is not properly initialized or if there is a mismatch in the field catalog or layout.

    Explanation:

    REUSE_ALV_POPUP_TO_SELECT is a function module used to display a popup selection screen with an ALV grid, allowing the user to select one or multiple entries. The function module returns a return code (return_code) indicating the result of the popup:

    • return_code = 0 means the user confirmed the selection.
    • return_code <> 0 means the user canceled or an error occurred.

    If the calling program expects only a successful return and does not handle other return codes, the system raises the warning message WXP737.


    Solution / How to Fix:

    1. Handle the Return Code Properly:

      In your ABAP code, after calling REUSE_ALV_POPUP_TO_SELECT, always check the return code and handle the cases where the user cancels or an error occurs.

      Example:

      CALL FUNCTION 'REUSE_ALV_POPUP_TO_SELECT'
        EXPORTING
          ...
        IMPORTING
          return_code = lv_return_code
        TABLES
          ...
        EXCEPTIONS
          error = 1
          OTHERS = 2.
      
      IF lv_return_code <> 0.
        " User canceled or error occurred
        MESSAGE 'Selection canceled by user' TYPE 'I'.
        EXIT. " or handle accordingly
      ENDIF.
    2. Check Parameters Passed:

      • Verify that the field catalog and layout parameters are correctly defined.
      • Ensure that the internal tables passed to the function module are properly filled and consistent.
      • Make sure that the ALV grid is properly initialized.
    3. Use Newer ALV Classes (Optional):

      If possible, consider migrating to the newer ALV classes like CL_GUI_ALV_GRID or CL_SALV_TABLE which provide better control and error handling.

    4. Debugging:

      • Set a breakpoint in the function module REUSE_ALV_POPUP_TO_SELECT to check why the return code is non-zero.
      • Check if the user is canceling the popup or if there is an internal error.

    Related Information:

    • SAP Note: Sometimes SAP releases notes related to ALV function modules and their behavior. Check SAP Support Portal for notes related to REUSE_ALV_POPUP_TO_SELECT or WXP737.
    • ALV Documentation: Review SAP documentation on ALV function modules and popup selection screens.
    • User Behavior: Often, this message is informational and indicates the user canceled the popup. It is not always an error but a warning to handle the situation gracefully.

    Summary:

    Aspect Details
    Cause User canceled ALV popup or unexpected return code from REUSE_ALV_POPUP_TO_SELECT.
    Effect Warning message WXP737 is raised indicating unexpected return code.
    Solution Check and handle the return code properly in your ABAP program after the function call.
    Additional Verify parameters, consider using newer ALV classes, debug if unexpected errors occur.
