On Enate we can configure how the company works i.e. Monday to Friday, 9-5.30 and can specify non working days in the year e.g. Christmas Day, May Day, Good Friday etc. Enate takes this calendar into account when calculating our work item due dates.
What would be great is if this data were to come across to Tableau so that our MI can be more dynamic and in bespoke reports we can calculate the difference between dates ensure that we factor in our working hours and dates. We have a number of requirements we would like to build in Tableau and at the moment they are not possible because of this limitation
