## Last 3 days average values per ID using date

Hi all,

I am trying to calculate last 3 days average values per ID. Below is sample data set:

 modelcode ordernumber Date DISCOUNTPERCENT TMAX E120XN 12462 21-03-13 100 40 E120XN 260701 28-07-11 30 40 E120XN 260702 28-07-11 30 40 E120XN 260703 28-07-11 30 40 E120XN 260691 28-07-11 30 40 E40HSD3 287077 04-05-11 42 42 E40HSD3 A17010 26-01-11 42 42 E40HSD3 A19142 30-04-11 42 42 E40HSD3 A10998 28-12-12 42 42 E40HSD3 A30618 21-04-11 42 42 E40HSD3 273464 01-06-12 41.907 42 E40HSD3 273465 01-06-12 41.907 42 E55XN 130120 01-11-10 45 42 E55XN 130122 01-11-10 46 42 E55XN 24131 09-06-12 99.999 42 E55XN 24130 15-06-12 43 42 E55XN 24129 09-06-12 99.999 42

I have calculated different variance of Tmax, and average of discount per ID and per day as there are many orders per day.

```Avg Discount %C =
DIVIDE(CALCULATE(sum(Hyster[DISCOUNTPERCENT]),ALLEXCEPT((Hyster),Hyster[modelcode], Hyster[Order Date].[Date]
)), [Model CountC])```

Then created if condition bucket for average discount and Tmax variances.

```Bucket = Switch ( True(),
And( [Avg Discount %C]>=-10 ,[Avg Discount %C] < Hyster[Fixed TMax Var 5%]) , "Green",
And( [Avg Discount %C]>=Hyster[Fixed TMax Var 5%],[Avg Discount %C] < Hyster[Fixed TMax Var 15%]) , "Yellow",
And(  [Avg Discount %C] >= Hyster[Fixed TMax Var 15%],[Avg Discount %C] < 500),  "Red"
)```

This Bucket value is assigned to Modelcode ID per day based on the average disclount.

Now I am trying to take the last 3 days data per Model Code and want to apply another condition saying if last 3 days Model Code Bucket values are all Red's then Red, if any one value is Green then Green else Yellow.

For this I have created column :

```Last 3T =
VAR __tmpTable = SUMMARIZE(FILTER(ALL('Hyster'),Hyster[modelcode]=EARLIER(Hyster[modelcode]) && Hyster[Order Date]<=EARLIER(Hyster[Order Date]) && Hyster[Order Date]>=EARLIER(Hyster[Order Date])-2),Hyster[Bucket])
VAR __rows = COUNTROWS(__tmpTable)
RETURN
IF(__rows = 1,MAXX(__tmpTable,Hyster[Bucket]),IF("Green" IN __tmpTable, "GG", IF("Yellow" IN __tmpTable, "Yellow", "Red")))```

But this is not giving the expected result.

The expected result should be Green in the Last 3T created column.

## Re: Last 3 days average values per ID using date

OK, first, you need to clean up your PBIX, you have some columns causing circular dependencies, like "If test". Get rid of that column. Also, for some odd reason it wasn't getting the correct modelcode at the beginning so I fixed that and cleaned up some code.

```Last 3TEst =
VAR __modelcode = MAXX(CALCULATETABLE('Hyster'),'Hyster'[modelcode])
VAR __tmpTable = SUMMARIZE(FILTER(ALL('Hyster'),Hyster[modelcode]=__modelcode),[Order Date],[Bucket])
VAR __maxDate = MAXX(__tmpTable,[Order Date])
VAR __tmpTable2 = TOPN(3,__tmpTable,[Order Date],DESC)
VAR __tmpTable3 = SELECTCOLUMNS(__tmpTable2,"__Bucket",[Bucket])
RETURN
IF(
CONTAINS(__tmpTable3,[__Bucket],"Green"), "Green",
IF(
CONTAINS(__tmpTable3,[__Bucket],"Yellow"),
"Yellow",
"Red"
)
)```

## Re: Last 3 days average values per ID using date

I believe the issue that you are facing is that when I originally replied to this, I was thinking that you wanted the last three days as in the last three actual days. So, in other words if your date was 3/21/2013, the last three days would be 3/21/2013, 3/20/2013 and 3/19/2013. Possibly 3/18/2013 as well depending on your definition of "last three days". But, now that I am looking a bit closer at your data, I believe that is not what you want. What you want is the last three days in your data, so for E120XN for 3/21/2013 you want the 3/21/2013 date as well as the 7/28/2011 date, correct?

In that case, you are probably going to need to use RANKX and/or TOPN to filter out your SUMMARIZE temp table so that you can filter it to the most recent three days in your data.

## Re: Last 3 days average values per ID using date

See if this works. First, create this calculated column:

`Rank = RANKX(ALL(Hyster),[Order Date])`

```Last 3T =
VAR __tmpTable = SUMMARIZE(FILTER(ALL('Hyster'),Hyster[modelcode]=EARLIER(Hyster[modelcode]) && Hyster[Order Date]<=EARLIER(Hyster[Order Date])),Hyster[Bucket])
VAR __tmpTable2 = TOPN(3,__tmpTable,1)
VAR __rows = COUNTROWS(__tmpTable)
RETURN
IF(__rows = 1,MAXX(__tmpTable2,Hyster[Bucket]),IF("Green" IN __tmpTable, "GG", IF("Yellow" IN __tmpTable, "Yellow", "Red")))```

## Re: Last 3 days average values per ID using date

Hi Greg,

In the solution you have provided the expected result is copied to the max date cell of the model code. But can we copy the expected result to all rows of the model code?

If you see in the above image, the last column should have only "Green" but there is "Red" also. Can we copy the expected result "Green" to all other rows of the Model Code?

## Re: Last 3 days average values per ID using date

OK, I'm still not sure I'm "getting" your logic for your last 3 calculation. So the way it works now is that it takes the MAX of the date row that it is in. It looks back through the last 2 dates prior to that (regardless of how long) and returns a category label essentially. So, on the first row, if you look at that row and the 2 previous you have Yellow, Green, Red. Since there is a Green, it is Green. In the second row, you would have Green and Red. Since there is a Green, it is Green. In the last row, you have only Red (there are no previous dates), so it is Red.

So, now what you are saying is that you don't care about the "last 3 days", we already established that it is the "last 3 dates", but you don't want that either, what it sounds like you really want is to always look at "the most recent 3 dates", correct? So, in essence, always get the MAX of all of the dates for an ID and then look at the previous 2 dates before that and determine the bucket. Do this regardless of how far back in time, so if you had 5 dates, all 5 would effectively be the exact same calculation, get the most recent and look back 2 days. Is that correct?

## Re: Last 3 days average values per ID using date

Hi Greg,
Once we get the result for last 3 days, say green can we copy the same green value for all the remaining days?
Or in a new column, so for the model code ID based on the last 3 days calculation the end result is green for example.

## Re: Last 3 days average values per ID using date

My thought is if we take max date for each Model Code ID and take the calculated bucket value. So we get the expected result value per Model Code ID at max date row. Can we copy the result value to all the rows of the Model Code ID

That's not really how it works. Let me adjust the formula based upon my new understanding.

```Last 3TEst =
VAR __modelcode = MAX([modelcode])
VAR __tmpTable = FILTER(ALL('Hyster'),Hyster[modelcode]=__modelcode)
VAR __maxDate = MAXX(__tmpTable,[Order Date])
VAR __tmpTable2 = TOPN(3,__tmpTable,[Order Date],DESC)
VAR __tmpTable3 = SELECTCOLUMNS(__tmpTable2,"__Bucket",[Bucket])
VAR __rows = COUNTROWS(__tmpTable)
RETURN
IF(__rows = 1,MAXX(__tmpTable2,Hyster[Bucket]),IF(CONTAINS(__tmpTable3,[__Bucket],"Green"), "Green", IF(CONTAINS(__tmpTable3,[__Bucket],"Yellow"), "Yellow", "Red")))```
