Row level calculation based on date selected

[Anonymous]

Hi,

  I have a table with a Original_Date field on each row. I will have a date slicer for user to pick the date. 

  I need to use a Matrix with Group, Tenant, Type in Rows and a new calculated field in Values. This new field will calculate Days_Outstanding (= User's Date - Original_Date). 

  The issue is that this calculation first needs to happen on each row and each Group+Tenant+Type is not unqiue, so I can't use User's Date - Max(Original_Date) in DAX. My idea is create a dynamic temp table that refreshes itself depend on User's Date but I don't know how.

  Here is an example in Excel: Col A-E are source data. Col F links to user's selected date so it's dynamic, then col G calculation will update. However I'm not sure how to implement something similar in Power BI using DAX.

Having problem to attach a pbix file, so I pasted the data here. Thank you!

ID	Group	Tenant	Type	Original_Date
1	A	Tenant A1	Rent	1/2/2018
2	A	Tenant A1	Rent	1/3/2019
3	A	Tenant A1	Payment	1/6/2021
4	A	Tenant A2	Rent	4/26/2019
5	A	Tenant A2	Rent	5/4/2018
6	A	Tenant A2	Payment	4/30/2020
7	B	Tenant B1	Rent	9/4/2019
8	B	Tenant B1	Payment	12/12/2018
9	B	Tenant B1	Rent	2/5/2020
10	B	Tenant B2	Rent	2/12/2020
11	B	Tenant B2	Payment	3/27/2018
12	B	Tenant B2	Rent	4/14/2020
13	C	Tenant C1	Rent	3/8/2018
14	C	Tenant C1	Rent	10/16/2018
15	C	Tenant C1	Payment	5/8/2019
16	D	Tenant D1	Rent	10/30/2018
17	D	Tenant D1	Payment	4/30/2020
18	D	Tenant D2	Rent	7/30/2018
19	D	Tenant D2	Rent	1/11/2019
20	D	Tenant D2	Payment	3/5/2019

You cannot update a table from a slicer as the model is completed and loaded. To achieve your goal, you can create a measure based on the user's date selection:

Days Outstanding = 
var __dateselected = SELECTEDVALUE(Dates[Date]) return
SUMX(
    Table3,
   DATEDIFF( __dateselected ,Table3[Original_Date],DAY )
)
