Effect
Syntax check for screen. 
 
The screen
description is taken from the field string h and the internal tables 
f, e, and m. The field string h
(screen header) should correspond to the structure D020S, the internal table f
(field list) to the structure D021S, the internal table e (flow logic) to
the structure D022S, and the internal table m (matchcode information) to
the structure D023S. For f, e, and m you can specify standard tables without secondary keys.
