DAX: Dynamic Filter on Min and Max selected Date

[denxx34]

I greet you,

just stuck on the following problem:

3 tables: Item, Stock, Calendar

The stock of the article is saved per day.

What I need...

1. I choose a period (From- To in a slicer from Calendar)

2. I need the value of the from-date for each article. (Min of selection)

3. And the value of the to-date. (Max of selection)

After that I need to calculate a difference to see the change per item in the selected period.

If an item starts later than the selected from date, then 0 should be returned as the result.

Example with two items:

Stock:

ItemNo		Date		Quantity
4711		01.01.2023		10
4711		02.01.2023		12
4711		03.01.2023		8
4711		04.01.2023		11
4711		05.01.2023		9
4711		06.01.2023		8
4711		07.01.2023		11
4712		03.01.2023		2
4712		04.01.2023		4
4712		05.01.2023		5
4712		06.01.2023		7
4712		07.01.2023		4

Item:

ItemNo		ItemName
4711		A
4712		B

Result for the selection 01/Jan/2023 - 06/Jan/2023 should be:

ItemNo		MinValue		MaxValue		Delta
4711		10		8		-2
4712		0		7		7

Thank you very much in advance!!

@denxx34 , Try a measure like

//Date table and Date is Joined
Delta =
var _max = maxx(allselected(Date),Date1[Date])
var _min = minx(allselected(Date),Date1[Date])
return
calculate( Max(Table[Quantity]), filter('Date', 'Date'[Date] =_max )) - calculate( Max(Table[Quantity]), filter('Date', 'Date'[Date] =_min))

You can sperate min and max two have two more measures
