Effect
Syntax check for dynpro
The dynpro
description is taken from the field string h and the internal tables
f, e, and m. The field string h
(dynpro 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. Standard tables without secondary keys can be specified for f, e, and m.
Example
DATA: DHEAD TYPE D020S, "dynpro header
DFIELDS TYPE TABLE OF D021S, "field list
DFLOWL TYPE TABLE OF D022S, "flow logic
MCINFO TYPE TABLE OF D023S. "matchcode information
If a syntax error is detected during the check, the fields f1, f2, and f3 are filled as follows:
