Variantenschnellauswahl

Mit diesem kleinen Gimmick stellen Sie dem Anwender eine Schnellauswahl der Varianten zur Verfügung. Ausserdem wird hier demonstriert, wie die Werte einer Variante übernommen werden können.

Die vorhandenen Varianten werden links am Rand angezeigt und können per Doppelklick übernommen werden. Auf Wunsch kann auch die Variante sofort ausgeführt werden.

Man könnte auch definieren, dass Varianten, die mit X beginnen, sofort ausgeführt werden, alle anderen werden nur geladen…

Desweiteren kann nachvollzogen werden, auf welch einfache Weise in Splitter mit ALV an ein Dynpro angebunden werden kann.

Ich habe den Report etwas auf Vordermann gebracht. Die alte Version hat mit dem Funktionsbaustein RS_VARIANT_CONTENTS und der manuellen Zuweisung der gespeicherten Variantenwerte über Feldsymbole gearbeitet. Die neue Version habe ich einerseits auf Methoden umgestellt und zudem verwende ich den Funktionsbaustein RS_SUPPORT_SELECTIONS, der die Übernahme der Feldwerte in das Dynpro automatisch macht.
