• What is the cause and solution for SAP error message SALV_EXCEPTION015 - Lists cannot be output in a container ?

  The SAP error message SALV_EXCEPTION015 indicates that there is an issue with trying to output a list in a container that is not supported. This typically occurs when using the SAP ALV (ABAP List Viewer) framework, particularly when working with the SALV (Simple ALV) classes.
  Cause:
  The error usually arises due to one of the following reasons:
  
  Incompatible Container: The output container (like a screen area or a custom control) is not suitable for displaying the ALV list.
  Incorrect Configuration: The ALV object may not be properly configured to output to the specified container.
  Missing or Incorrect Parameters: The parameters passed to the ALV display method may be incorrect or missing.
  
  Solution:
  To resolve the SALV_EXCEPTION015 error, you can try the following steps:
  
  
  Check Container Type: Ensure that the container you are trying to use is compatible with the ALV output. For example, if you are using a custom container, make sure it is properly defined and initialized.
  
  
  Use Standard Containers: If possible, try using standard containers like CL_GUI_ALV_GRID or CL_GUI_ALV_LIST to see if the issue persists.
  
  
  Review Code: Check your ABAP code where you are creating the ALV object and ensure that you are correctly specifying the container. For example:
  DATA: lo_alv TYPE REF TO cl_salv_table.
  cl_salv_table=>factory(
    IMPORTING
      r_salv_table = lo_alv
    CHANGING
      t_table      = it_data ).
  
  
  Initialization: Make sure that the container is properly initialized before you attempt to display the ALV. For example, if you are using a custom container, ensure that it is created and assigned correctly.
  
  
  Check for Exceptions: Implement exception handling in your code to catch and handle any exceptions that may arise during the ALV display process.
  
  
  Debugging: Use the debugger to step through your code and identify the exact point where the error occurs. This can provide insights into what might be going wrong.
