Manipulation of Table Control
Introduction
A table control is an area on the screen in which the system displays data in tabular form. It is
processed using a loop.
Benefits of using a table control are
Resizable table for displaying and editing data.
The user or program can change the column width and position, save the
changes, and reload them later.
Check column for marking lines; marked lines are highlighted in a different color.
Line selection: single lines, multiple lines, all lines, and deselection.
Column headings double as pushbuttons for marking columns.
Scrollbars for horizontal and vertical scrolling.
Any number of key (leading) columns can be set.
Go to SE38 and type Program Name and click CREATE
Select type as MODULE POOL and status as TEST PROGRAM and click SAVE
Select Local Object ( You can also select your own package and save)
Click the icon (Display Object List) in the toolbar
Write the below coding (Defining Internal tables for table controls SOURCE and
DESTINATION)
(Cont.)Define table controls SORUCE and DESTINATION to be created in the screen
Right Click the progam name and select Create->Screen
Provide screen number (Here 9000) and click CONTINUE
Provide Short Description and click LAYOUT in the toolbar
Select TABLE CONTROL icon in the toolbar
Tap on the screen to create table controls as shown below
Click DICTIONARY/PROGRAM FIELDS in the toolbar
Enter the structure defined in the program and click GET FROM PROGRAM and select all
fields
Click on the table control to copy the structure
Provide the following attributes in the attribute panel for each table control
Create push buttons as shown below using PUSH BUTTON icon in the toolbar and provide
attributes for each element as following and Save the screen
Double click on screen 9000 and enter the below code in the flow logic tab
Double click on STATUS_9000 and select YES
Write the below code in the generated module block
(Cont.)
(Cont.)
Add a code MODULE modify_source and double click on it and select YES
Write the below code in the generated module block
Double click USER_COMMAND_9000 and select YES
Write the below code in the generated module block and activate program

Right click on program name and select Create->Transaction
Provide Transaction Name and short description and select CONTINUE
Provide attributes shown below and save and execute the program
EXECUTE : Activate Program and Right click Program name and select
Execute->In a new window
OUTPUT :
Select All
Deselect All
