Declaration of Table Controls
1. CONTROLS contrl TYPE TABLEVIEW USING SCREEN screen no.
Declaration of Tabstrip Controls
2. CONTROLS contrl TYPE TABSTRIP.
With the CONTROLS statement, for each screen used in the program, all table controls and tabstrip controls that are defined there have to be declared in the declaration section, otherwise an untreatable exception occurs when the corresponding screen is called. For contrl, the name of the control that is defined in the screen has to be specified directly. After TYPE, TABLEVIEW or TABSTRIP must be used to specify whether it is a table control or a tabstrip control.
For each control, the CONTROLS statement creates a structure with the name of the control in the ABAP program. The structure components enable the respective control to be processed in the ABAP program.
For table controls, corresponding loops have to be programmed in the
screen flow logic. For tabstrip controls, suitable subscreens have to be called.
