How to get the additional fields in table depending on variable ?

[suvechha]

Hi All ,

I am transforming Qliksense App to Power Bi App.

Can anyone please help how to approach - I have to create a variable -  vTMP_Max_Date

MaxDate:
Load Max(_Date) as _MaxDate
Resident PH;

LET vTMP_Max_Date = Num(Peek('_MaxDate', 0, 'MaxDate'));

After creating the variable vTMP_Max_Date 

I need to add the following field in the current table which is created by evaluating the variable vTMP_Max_Date 

Join(PH)
load distinct _Date,
Interval($(vTMP_Max_Date) - _Date,'d') As PH.Last_n_days,
if(Interval($(vTMP_Max_Date) - _Date,'d') =0,1,0) as PH.count_today,
if(Interval($(vTMP_Max_Date) - _Date,'d') =7,1,0) as PH.count_7_days_ago
resident PH
;

Currently I have the PH table with below columns

I want to get the columns

PH.Last_n_days,

PH.count_today,
PH.count_7_days_ago like below

@suvechha Sorry, I don't speak Qliksense. These things usually go faster if you just post sample data and expected output.

Sorry, having trouble following, can you post sample data as text and expected output?

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.
