DAX for open/active list of tasks or invoices

Hi group

I'm wanting to list open tasks/orders (or could be used for unpaid invoices).

I have read alberto ferrari's but that's counting & averaging & I can't seem to get what I want - just a list of data (task id)

when a task is in progress between a selected date range.

This is the code I have so far adapted from Alberto's

& my model:


Thanks for any assistance - i don't know how to attach my dummy data PIBX

Hey @Peta_g 


besides the whitepaper you mentioned already I also urgently recommend you to read this great blogpost by Jason Thomas:


Looking at your DAX statement and your relationship screenshots, there are two things.


  1. Referencing the date column
    As you define a measure  it's necessary to wrap an aggregation function around the column reference like so MAX('<tablename>'[<columnname>]) This is due to the filter context a measure will be evaluated in.
  2. Date relationship
    A lot of solutions that are circling around the event-in-progress challenge leverage a date table that is not relateted to the the fact table, I assume this is your table "work".
    Tasks/Invoices will be filtered immediately by the selected dates in accordance with the relationship. From my experience the same MAXDate can not be used for the start and end date, this just works, if a task will be closed at the same date.

If you need more help, please consider to create a sample pbix file that reflects your data model, upload the file to onedrive or dropbox, and share the link.
