Are you looking for ways to automate some of your routine accounting functions, like reconciling sub ledgers to the general ledger?   Microsoft has recently created some examples using Power Automate Desktop (think of it like Task Recording on steroids). It can not only automate steps through Dynamics 365, but it can also automate Excel and other applications. In one example from Microsoft they automate the AR to GL reconciliation: Automatic running of the AR aging and the customer/ledger reconciliation reports. Power Automate then extracts data from both reports in Excel and compares the balances. Power Automate then posts a Team message letting you know the subledger is in balance. Power Automate saves the reports with the date in the file name, so there is backup. Microsoft Directions & Example   I working with the example, I needed to make a couple of adjustments to the sample flow that was provided but I was able to get it to work.

COVID 19 Dashboard - Article 3 - Adding some key measures - unique time functions

-

I will continue to build on my earlier posts about my COVID19 Dashboard.  In this series, I am writing a few different blog articles describing not only how I built it, but some things I learned in the process.
The current list of planned topics include:

PART 3 – Adding some key measures


In my earlier posts, I spent time explaining where I acquired the data and some key steps I took in transforming the data into the data model.  In this post, I will explain some of the DAX I used to create some of the key measures for the visualizations.  One of the first steps in design is to identify what questions you are trying to answer or the story you are trying to tell with your visualizations and reports.  In thinking about everything going on with Covid 19, I felt it was not only important to know how many total cases and total deaths, but I wanted to understand how the numbers were changing daily.
  • What was the rate of increase?
  • Is it increasing faster today than it did yesterday?
  • How long did it take for cases to double?
  • How long until they double again?



Let’s look at four of the measures that are used in this dashboard.
  • Daily increase cases 
  • Confirmed cases DoD% 
  • Cases double in 
  • Cases est. to double again

Daily increase cases – this measure looks at the percent of change between the new cases each day.  This is a percent increase math problem.  Percent Increase = (today’s new cases – yesterday’s new cases) / yesterday’s new cases.  So, to calculated this in DAX, we need today’s cases amount and yesterday’s cases amount.  Since today’s cases will be the maximum date in the data, I used the following DAX formulas to calculate today’s and yesterday’s cases.

First, I crease a Sum Cases measure so I could reference it in other measure.  

Sum Cases = sum('US Covid Activity'[Daily Cases])

New Cases Today = CALCULATE([Sum Cases],FILTER(ALL('Date'),'Date'[Date]=MAX('Date'[Date])))

New Cases Yesterday = CALCULATE([Sum Cases],FILTER(ALL('Date'),'Date'[Date]=MAX('Date'[Date])-1))

Once I had the cases I could use a simple DIVIDE function.

Daily Increase Cases = DIVIDE([New Cases Today]-[New Cases Yesterday],[New Cases Yesterday],0)

Confirmed cases DoD% - this measure looks at the day of day percent growth in total cases.  This is also a percent increase math problem.  Percent Increase = (today’s total cases – yesterday’s total cases) / yesterday’s total cases.

In this case, I used a Variable to calculate the Previous Day

Confirmed Cases DoD% =
//Calculate Day of Day % of change
//Set variable for Prior day Life to Date total
VAR __PREV_DAY =
    CALCULATE(
        SUM('US Covid Activity'[Daily Cases]),
        DATEADD('Date'[Date], -1,DAY)
    )
//Calculate Net Change in cases (Today LTD less Yesterday LTD)
//Divided by Yesterday LTD
RETURN
    DIVIDE(
        SUM('US Covid Activity'[Daily Cases]) - __PREV_DAY,
        __PREV_DAY
    )

Cases Doubles In – This measure looks back in time to see how many days it has taken to double the number of cases.  For example, if today’s total cases are 100,000, then how many has it been since the cases were 50,000.  This seemed to be a complex problem, but fortunately an internet search did not let me down.  I was able to find a close example at https://www.thebiccountant.com/2020/03/22/calculating-doubling-times-with-dax-in-power-bi/  I had to make some slight changes to the example provided to get it to work in my scenario.  Below is the code I used.

Doubled in Days =
//SET THE CURRENT DATE
VAR CURRENTDAY = MAX('US Covid Activity'[Date])
// GET HALF OF TODAYS VALUE
VAR THRESHOLDVALUE = 
     CALCULATE(SUM('US Covid Activity'[Confirmed Cases]),'US Covid                           Activity'[Date]=CURRENTDAY) / 2
//Get the day when the number of cases was half as much as today
//FILTER returns dates at which the total sum of confirmed cases was below the threshold
VAR DayOfHalf =
     CALCULATE(MAXX('US Covid Activity','US Covid
     Activity'[Date]),FILTER(ADDCOLUMNS(SUMMARIZE(ALL ('US Covid
     Activity'),'US Covid Activity'[Date]), "AMOUNT",CALCULATE(Sum('US Covid
     Activity'[Confirmed Cases]))),[AMOUNT]<=THRESHOLDVALUE))
//Calculated the date difference between today and the date the amount was half
VAR DoublingTime = DATEDIFF(DayOfHalf,CURRENTDAY,DAY)
     RETURN
     DoublingTime


Cases Est. to Double Again – This measure looks at the confirmed cases day over day % growth that was calculated above, and estimates how many days until the number of cases will double.  This uses the doubling time formula.  I was able to find information on this math formula at https://www.double-entry-bookkeeping.com/number-of-periods/doubling-time-formula/

     The formula for doubling time is LN(2)/LN(1 + i).  
  • The (i) is the rate (confirmed cases DoD%).  
  • LN returns the natural logarithm of a number.  

     The DAX formula was  

           Est. Days to Double = ROUND(DIVIDE(ln(2),ln(1+[Confirmed Cases DoD%])),0)

           Note- I used the Round function to round to the nearest whole day.

I also created these measures for the global cases table in my data model.

In my next article, I will look at some additional measures I created around U.S. population.

Microsoft has recently released two Copilot applications to work with Dynamics 365 Finance & Supply Chain. These solutions are still in preview, so it should only be uses in sandbox environments to evaluate and learn how they will work with your organization. Prior to installing it is important to make sure your environment meets the requirements. Dynamics 365 Finance & Supply Chain requires the latest hotfix on Dynamics 365 Finance version 10.0.34 (10.0.1591.107) and version 10.0.35 (10.0.1627.70) and later. In addition, the solutions rely on the Power Platform and Dataverse, so it is important to have the environments connected and user security set appropriately. For more details on the prerequisites and the installation instructions you can follow the Microsoft installation documents. Copilot in Microsoft Dynamics 365 Finance Copilot in Microsoft Dynamics 365 Supply Chain Let's look at what these two copilots provide to users Copilot in Microsoft Dynamics 365 Finance C...

Have you ever wanted to put a website or a model-driven Power App in one of your existing Dynamics 365 Finance workspaces or forms?  You might already know you can create a new workspace with a website, but did you know you can add the website to an existing workspace? Here is an example of the Vendor invoice entry workspace with the Invoice Capture Power App embedded. Prior to using this feature, you need to turn on "Saved views support for workspaces" in feature management. Once this feature is enabled you can follow the following steps to add the Invoice Capture app or any model-driven Power App or website to an existing workspace. Open the vendor invoice entry workspace From Options - choose Personalize this page From personalize menu - select the 3 dots - and then Add an app Once that is selected (the screen goes gray) - click on the section header where you want to add the app (in my example I put it in Links) On the Add an app menu - choose Website Give it a name (my e...
