Use

If you use the ALV configuration model, the objects for all standard ALV functions are generated automatically. The objects are from class CL_SALV_WD_FUNCTION_STD.

With self-defined functions, you generate a function object of class CL_SALV_WD_FUNCTION with each function. You can create as many function objects as you want and arrange them in the toolbar.

You can make settings for:

  • Creating an object for a user-defined function

  • Getting object for a function

  • Setting and Getting Information About a Function

  • Deleting an object for a user-defined function

Creating an object for a user-defined function

When you generate a self-defined function, you specify a unique ID (type STRING), with which you later address the function.

To generate a function object, you use the methods of interface class IF_SALV_WD_FUNCTION_SETTINGS (implementing class CL_SALV_WD_CONFIG_TABLE).

Getting an Object for a Function

To make settings for a function object, you must first call a suitable GET method. You can choose which function you want to get from the toolbar:

  • All standard ALV functions or a specific function

  • All self-defined functions or a specific function

  • Only the standard ALV functions on one side of the toolbar

  • All self-defined functions on one side of the toolbar or a specific function

Various methods are available for this purpose in interface class IF_SALV_WD_FUNCTION_SETTINGS (implementing class CL_SALV_WD_CONFIG_TABLE):

Informationen zur Funktion setzen und holen

You can examine a function in the toolbar to determine whether it is a standard ALV function or a self-defined function.

You also specify the following properties:

  • ID

    The ID of a standard ALV function is created automatically. It contains information about the standard ALV function.

    The ID of a user-defined function is the ID you assigned the object when you created it.

  • Group

    You can use the group name to group functions according to any criteria.

  • Position in der Toolbar (siehe Positionieren in der Toolbar )

  • Sichtbarkeit und Aktivierung (siehe Steuern von Sichtbarkeit und Aktivierungsstatus )

For the information, you use methods from class CL_SALV_WD_FUNCTION or class CL_SALV_WD_FUNCTION_STD.

Methods for information about function objects

Deleting a Function

You can only delete objects from user-defined functions; you cannot delete objects from standard ALV functions.

To delete a user-defined function, specify the function ID. To do this, you use the methods of interface class IF_SALV_WD_FUNCTION_SETTINGS (implementing class CL_SALV_WD_CONFIG_TABLE).
