LOOP AT SCREEN

Short Reference

Syntax

LOOP AT SCREEN [INTO wa].
  ...
ENDLOOP.

Effect

The statement LOOP AT SCREEN ... ENDLOOP define a loop around a statement block. For every screen element of the current dynpro, to which adynprofield is assigned, one loop pass is executed. After the LOOP statement, either the predefinedworkarea screenor the workarea wa (when using INTO) contains the properties of the respective screen element. wa must have the same data type as screen.

While processing a table control or asteploop (that is, within a LOOP loop of thedynproflow logic), for its screen elements the current properties are determined in the current row orgroup. Outside of the processing of a table control or step loop, for its screen elements the statically predefined properties of all rows or groups are determined.

Note

The LOOP AT SCREEN statement behaves like the statement LOOP for a loop, using an internal table withheader line, whereby a system table is used instead of an internal table.

Example

Refer to dynpros, dynamic screen modification.
