my problem ist actually quite simple. I want to calculate the number of workdays (monday till friday) between two given timestamps. The relevant function requires me to reference a specific calendar table from the data model. Within the data model options, however, the possiblity exists to define a custom calendar without implementing a dedicated table (simply by selecting relevant days and time windows). My questions is: How do I reference this adjusted standard calendar as a parameter for the function workdays_between or is it possible to generate a table from the customized calendar?
