Lookup value if date is between two dates

Hi   I'm new to PowerBI and the DAX syntax. I have 2 tables (Sprints and WorkItems). All date columns are formatted as Date   Sprints table: (columns StartDate, FinishDate and SprintNumber) ...

    I don't think you've told us all about the model... I suspect there are relationships between the two tables based on the date fields.

     

    Try this

    CreatedInSprint =
var __date = WorkItems[fields_SystemCreatedDate]
return
	MAXX(
		FILTER(
			Sprints;
			AND(
		    	Sprints[attributes_startDate] <= __date,
		    	__date <= Sprints[attributes_finishDate]
		    )
		),
		Sprints[SprintNo]
	)

    This should work correctly on the assumption that there is always at most one sprint returned by the logical condition in FILTER. If there happen to be many, then the maximum SprintNo will be returned.

Great advice Anonymous, thank you!

I made all necessary changes as far as Calendar is concerned and results are verified on day basis.

I've noticed though that Date Hierarchy is not available to use in the visual. Is filtering inside the '# Opportunities' measure responsible for that?

Nope. The Date hierarchy that's generated by Power BI automatically should NEVER be relied upon but in the simplest of models. If you have a decent model and want to keep your sanity, you should never rely on this functionality. It's for newbies who have no idea what a good model is and what good DAX means. So, please stay away from it. You should always, ALWAYS, have a calendar of your own with all the entities defined in it. The functionality to create an automatic hierarchy can be switched no/off in the settings of the file or globally. My strong suggestion is to turn it off forever and forget it has ever existed. There are numerous YT videos by Marco Russo and Alberto Ferrari that say you should forget this functionality unless... you like asking for troubles. Make you own calendar and you'll be safe.
