Creating a Table Control

In the Screen Element Attributes window, assign aname to the table control and set initial (static)

attributes.

Some attributes are With column headers, Resizing,

Separators, With title, Line selection column, No offixed columns etc.

IBM Global Services


When creating a table control, the

system automatically proposes a

selection column.

A selection column allows users to

choose a line of the table control. The selection column elements

behave like a checkbox.

The field name must be entered in the

attributes of the table control.

Creating Table Control

Declare CONTROLS statementwith type TABLEVIEW.

The user can modify the Table

Control attributes at runtime.

Use REFRESH

CONTROL FROM SCREEN to

reset a table control to its initial

attributes.

Type TABLEVIEW has a complex structure containing

individual fields and an internal table

A Table control can be processed with or without an internal table:

*Processing without an internal table*

PROCESS BEFORE OUTPUT.LOOP WITH CONTROL items.

Declare Table Control

To declare table control, use the syntax found below:CONTROLS TYPE TABLEVIEW USING SCREEN

.

Processing Table Control Through Loop Endloop

You can process the screen table using a LOOPstatement by:

Looping only through the screen table

Looping through screen table and an internaltable in parallel

If you have table control in a screen, you must have

LOOP ENDLOOP blocked both in PBOand PAI.

SY-STEPL contains the current loop iteration.


16/26

IBM Global Services


Using LOOP Statements

Syntax:LOOP AT CURSOR

[WITH CONTROL ]

[FROM ] [TO ].

ENDLOOP.

The FROM .. TO clause is for step loops

When using step loops, omit the CURSOR parameter in the PAI event.

The FROM and TO parameters are only possible with step loops. The

WITH CONTROL parameter is only used with table controls.

CURSOR contains the current cursor row

Use TC-CURRENT_LINE as the cursor

*Processing with an internal table*

PROCESS BEFORE OUTPUT.

LOOP AT itab WITH CONTROL items CURSOR items-CURRENT_LINE.

ENDLOOP.

PROCESS AFTER INPUT.LOOP AT itab WITH CONTROL items.

MODULE ctrl_pai.

The fields in the table control and the internal table work area needs to have the

same structure and names for automatic transport of data between the ABAP

program and the screen.

Summary

A table control is an area on the screen where the system displays data in atabular form. It is processed using a loop.

Lines in a table control may contain dictionary table fields, keywords, input/output

fields, radio buttons, checkboxes, radio button groups, and pushbuttons.A line

can be up to 255 columns wide. Each column may have a title.

When creating a table control, the system automatically proposes a selectioncolumn.

A selection column allows users to choose a line of the table control.

When processing a table control in the program, you will also need to declare a

CONTROLS statement with type TABLEVIEW (in the TOP INCLUDE of your

program).

Summary (Contd.)

A Table control can be processed with or without an internal table. You can use the Customizing button (in the top right corner) to save the

current setting (column widths and column positions) and use it as the initial

value for the next call.
