Column Header

The column header displays the name of a column for the user. You are able to define three different texts as column header.

Use

You are able to make the following settings for the column header:

Determine the Wording of the Column Header
Display or Hide Column Header
Determine whether the user can sort the table according to this column by clicking on the column header
Determine Tooltip for the Column Header
Display an icon (only tree structure)

Determine the Wording of the Column Header

The column header is a property of the COLUMN object. In this way you are able to specify the column header for every column in the internal data table.

You can specify three different variants of the column header: The long, medium, and short column header. If the user changes the column width, the column header that fits the column best is automtically used.

Note

If the user changes the column width, the column header that fits the column best is automatically used. A special case is the column header of the hierarchy column in the tree structure:

ALV Tool	Display type	Function available
Simple, Two-Dimensional Table	Classic ABAP List	Yes
Fullscreen	Yes
In the Container	Yes
Hierarchical-sequential list	Classic ABAP List	Yes
Tree structure	Fullscreen	Yes
In the Container	Yes

Function	Class	Method
Determine version of the column header	CL_SALV_COLUMN	SET_LONG_TEXT SET_MEDIUM_TEXT SET_SHORT_TEXT
Get current column header	GET_LONG_TEXT GET_MEDIUM_TEXT GET_SHORT_TEXT
Determine column header of the hierarchy column of a tree structure	CL_SALV_TREE_SETTINGS	SET_HIERARCHY_HEADER
Get column header of the hierarchy column of a tree structure	GET_HIERARCHY_HEADER

Display or Hide Column Header

You are able to determine whether the column header is visible or not in the ALV output. You make this setting for all column headers of the ALV output.

ALV Tool	Display type	Function available
Simple, Two-Dimensional Table	Classic ABAP List	Yes
Fullscreen	Yes
In the Container	Yes
Hierarchical-sequential list	Classic ABAP List	Yes
Tree structure	Fullscreen	No
In the Container	No

Function	Class	Method
Display or hide column header	CL_SALV_COLUMNS_LIST	SET_HEADERS_VISIBLE
Check whether column headers are being displayed or hidden	IS_HEADERS_VISIBLE

Sort by Clicking on Column Header

You are able to determine that the column header serve as a pushbutton for sorting the table. The sort direction is then indicated as a small arrow pointing up or down.

ALV Tool	Display type	Function available
Simple, Two-Dimensional Table	Classic ABAP List	No
Fullscreen	No
In the Container	Yes
Hierarchical-sequential list	Classic ABAP List	No
Tree structure	Fullscreen	No
In the Container	No

Function	Class	Method
Set column header as pushbutton for sorting the table	CL_SALV_ FUNCTIONAL_SETTINGS	SET_SORT_ON_ HEADER_CLICK
Check whether column header is set as pushbutton for sorting the table	IS_SORT_ON_ HEADER_CLICK

Determine Tooltip for the Column Header

You are able to define a text that will be displayed when the user rests the mouse pointer on the column header for a moment.

ALV Tool	Display type	Function available
Simple, Two-Dimensional Table	Classic ABAP List	Yes
Fullscreen	Yes
In the Container	Yes
Hierarchical-sequential list	Classic ABAP List	Yes
Tree structure	Fullscreen	Yes
In the Container	Yes

Note

If the user changes the column width, the tooltip that fits the column best is automatically used. A special case is the tool tip of the hierarchy column in the tree structure:

Function	Class	Method
Determine tooltip for the column header	CL_SALV_COLUMN	SET_TOOLTIP
Get current tooltip for a column header	GET_TOOLTIP
Set tooltip for hierarchy column of a tree structure	CL_SALV_ TREE_SETTINGS	SET_HIERARCHY_TOOLTIP
Get tooltip for hierarchy column of a tree structure	GET_HIERARCHY_TOOLTIP

Display Icon

In the column header of the hierarchy column for a tree structure, you can display an icon.

ALV Tool	Display type	Function available
Simple, Two-Dimensional Table	Classic ABAP List	No
Fullscreen	No
In the Container	No
Hierarchical-sequential list	Classic ABAP List	No
Tree structure	Fullscreen	Yes
In the Container	Yes

Function	Class	Method
Display icon in the column header of the hierarchy column	CL_SALV_ TREE_SETTINGS	SET_HIERARCHY_ICON
Get icon currently being dispalyed	GET_HIERARCHY_ICON
