Bonjour,

Je souhaite effectuer un calcul de temps de traitement d'un dossiers de support à partir d'un calendrier (jours et heures ouvrés). Je ne vois pas comment procéder. Si quelqu'un a un exemple d'utilisation de calendrier dans un état Crystal Reports XI?

Cordialement

[campia]

Dans ton traitement de dossier de support, as-tu une date de création et de résolution?? Tu pourrais alors utiliser des formules...

[battl14]

C'est ce que je souhaite effectuer mais en me basant sur un calendrier qui prend en compte les jours et heures ouvrés ainsi que les jours fériés.

[kikidrome]

Pour les samedi et dmanches, tu as

DayOfWeek (date)

Merci kikidrome,

Mais il faut aussi que je me base par rapport à une plage horaires,

Cordialement
