Daten aus Query lesen

Hier erfahren Sie, wie Sie mittels Funktionsbaustein auf die Daten eines Queries zugreifen können.

Um Daten aus einem Query zu lesen, können Sie den Funktionsbaustein RRW3_GET_QUERY_VIEW_DATA verwenden. Dieser kann remote aufgerufen werden.

Sie müssen den Infoprovider und den Querynamen übergeben sowie notwendige Selektionsparameter (Select-Options, Intervalle oder Parameter).

Der Infoprovider wird automatisch eingbelndet, wenn Sie in Transaktion RSRT den Quernamen eingeben.

Bei der Übergabe der Parameter müssen Sie den technischen Namen der Variablen verwenden.

Die technischen Namen stehen in der Tabelle GT_TEXT_SYMB, wenn Sie den Baustein einmal aufrufen. Es gibt jeweils eine Zeile für den Namen (VARIABLE_xyz) und eine für den Wert (VARVALUE_xyz).

TIPP:
Der Funktionsbaustein UMK_BW_QUERY_VIEW_DATA ruft den gleichen Baustein auf, wandelt aber das Ergebnis in XML um.

Beschreibung

Das folgende Coding ruft eine Query im entfernten BW-System auf und gibt die Daten in einer Liste aus. Zudem werden die Daten in einer internen Tabelle gesammelt und erneut ausgegeben.

Falls der Query mehr als sechs Spalten hat, müssen Sie den Typen TY_BWDATA anpassen. Theoretisch könnte die erforderliche Tabelle auch dynamisch generiert werden.
