Tabstrip in selection screen

To define a tabstrip area with tab pages in selection screen, use the following statements in your selection screen definition:


SELECTION-SCREEN: BEGIN OF TABBED BLOCK FOR LINES,
TAB () USER-COMMAND
[DEFAULT [PROGRAM ] SCREEN ],
TAB () USER-COMMAND
[DEFAULT [PROGRAM ] SCREEN ],
...
END OF BLOCK .


This defines a tabstrip control with size . The tab pages , ... are assigned to the tab area. defines the width of the tab title. You must assign a function code area to each tab title.

For each tab title, the system automatically creates a character field in the ABAP program with the same name. In ititialization, you can assign a text to the field. This then appears as the title of the corresponding tab page on the selection screen.

You must assign a subscreen to each tab title. This will be displayed in the tab area when the user chooses that title. You can assign one of the following as a subscreen:



1. A subscreen screen defined using the Screen Painter.
The dialog modules containing its flow logic must be defined in the current ABAP program.

2. A selection screen subscreen, defined in an ABAP program.
User actions will trigger the AT SELECTION-SCREEN event at least twice – firstly for the "included" selection screen (we can use it for validation), then for the selection screen on which it appears.

This is simple program with three tab title.
Tab1 demonstrating input validation.
Don't forget to create subscreen 0300 for Tab3.

It's great to see an actual EXPLANATION rather than just the code. Thanks for providing this post. I was stuck because I was clearing SSCRFIELDS-UCOMM in my AT SELECTION-SCREEN and your post helped me see that mistake.
