I am trying to calculate how long it takes for incoming tickets to be resolved excluding weekends and holidays. I posted earlier a message about this but the data columns were old so I am trying to get a solution for my problem. Since I just started using Power BI, please give a solution in baby steps.
Seems like your table name is incorrect and it should be the one that is highlighted in yellow in your image. Also, you will need to update ","'s to ";" in your third line (including the name of your measure)
