Spécification de la position absolue de l élément du tableau croisé dynamique

Contents
[ ]

Le code d’exemple suivant crée un tableau croisé dynamique et spécifie ensuite les positions des éléments du tableau croisé dynamique dans le même nœud parent. Vous pouvez télécharger les fichiers Excel source et Excel de sortie pour votre référence. Si vous ouvrez le fichier Excel de sortie, vous verrez l’élément du tableau croisé dynamique “4H12” est à la 0e position dans le parent “K11” et “DIF400” est à la 3e position. De même, CA32 est à la position 1 et AAA3 est à la position 2
