Selecting Cells, Rows and Columns 

Use

You are able to use your application to determine which areas are selected when the ALV output is being displayed. In the simple, two-dimensional table and hierarchical-sequential list, you are also able to change whether and under what conditions users are able to select areas of the ALV output. To do this, use the selection type in list-type ALV outputs. In tree structures, you determine whether each individual node or item can be selected or not.

Current Cell

The current cell indicates the position of the cursor in the simple, two-dimensional table and the hierarchical-sequential list.  The current cell is highlighted differently from the selected cells. In this way you are able to recognize the current cell when you are in a selected area.

Features

You can make the following settings for the selection in the ALV output:

·        Get settings for selection and information on the selected areas

·        Set selection type

·        Enable selection of nodes and items

·        Select area

Get Information on Selections

The method GET_SELECTIONS that returns the selection object exists in each main ALV class.  With this object, you get the desired information with various getter methods.

Methods

Function	Class	Method
Get selection object	CL_SALV_TABLE CL_SALV_HIERSEQ_TABLE CL_SALV_TREE	GET_SELECTIONS
Get a selection object for a hierarchy level	CL_SALV_HIERSEQ_LEVEL	GET_SELECTIONS

Set Selection Type

With the selection type, you set which cells users are able to select simultaneously, that is, whether and how they can combine the selections. The selection type has different effects in the various display types.
