SAP Size of ALV Output, Columns, and Cells in SAP Netweaver

By default, the size of the ALV output, columns, and rows depends on their content. This means:

● A column is at least as wide as its widest cell.

● The ALV output is at least as wide as all its columns together.

● A row is at least as high as its highest cell.

You can easily increase the width of the ALV output and columns by specifying the required width. Decrease the width, however, is not as easy. First of all, you freeze the layout of the ALV output. This assigns the same width to all columns. You can then specify the required width for each column. You can make the following settings for the size of the individual areas:

● Change the width

● Change the height

You can only control the height of the rows using their content (for example, using the graphic size or multiline text).

● Freeze the table layout

Changing the Width

To change the width of an area, you use the methods of the classes for the areas.

Methods for Changing the Width

Function	Class	Method
Specify width of ALV output	IF_SALV_WD_TABLE_SETTINGS	SET_WIDTH
Specify width of column	CL_SALV_WD_COLUMN
Specify width of business graphic	IF_SALV_WD_GRAPHIC_SETTINGS
Specify width of cell Only with the following cell editors:		SET_WIDTH or SET_WIDTH_FIELDNAME
Button	CL_SALV_WD_UIE_BUTTON
Dropdown list box	CL_SALV_WD_UIE_DROPDOWN_ BY_KEY
Image	CL_SALV_WD_UIE_IMAGE
InputField	CL_SALV_WD_UIE_INPUT_FIELD
ProgressIndicator	CL_SALV_WD_UIE_PROGR_ INDICATOR
ToggleButton	CL_SALV_WD_UIE_TOGGLE_ BUTTON
ValueComparison	CL_SALV_WD_UIE_VALUE_CMP
Get width of ALV output	IF_SALV_WD_TABLE_SETTINGS	GET_WIDTH
Get width of column	CL_SALV_WD_COLUMN
Get width of business graphic	IF_SALV_WD_GRAPHIC_SETTINGS
Get width of cell (only with cell editors listed above)		GET_WIDTH or GET_WIDTH_FIELDNAME

Changing the Height

You specify the height of the ALV output using the number of rows that are to be displayed at a time.

If the number of data records is less than the number of visible rows, empty rows are automatically appended to the end of the ALV output. You can specify that no empty rows are to be appended and that the height of the ALV output therefore adjusts itself according to the number of data records.

To do this, you use the methods of interface class IF_SALV_WD_TABLE_SETTINGS (implementing class CL_SALV_WD_CONFIG_TABLE).

Methods for Changing the Height

Function	Method
Specify number of visible rows	SET_VISIBLE_ROW_COUNT
Get number of visible rows	GET_VISIBLE_ROW_COUNT
Append empty rows	SET_DISPLAY_EMPTY_ROWS
Check whether empty rows are appended	GET_DISPLAY_EMPTY_ROWS

To display all data records of the internal data table, set the number of visible rows to -1.

Freezing the Table Layout

Freezing the layout of the ALV output can be used to make columns narrower than their content dictates.

To do this, you use the methods of interface class IF_SALV_WD_TABLE_SETTINGS (implementing class CL_SALV_WD_CONFIG_TABLE).

Methods for Freezing the Table Layout

Function	Method
Freeze the table layout	SET_FIXED_TABLE_LAYOUT
Check whether table layout is frozen	GET_FIXED_TABLE_LAYOUT
