Solving Real World Scenarios with Microsoft Flow – Challenge No. 3 – Part two

To get things started I use a simple daily schedule – nothing special here:

Then I drag a Data Operations – Compose step on the flow. I use this to calculate the previous day. I have found out that I have to enter the expression with leading and trailing double quotes as otherwise it won’t work.

What I find very strange here is the fact that I can’t edit the item anymore after I have saved it. Seems like a bug to me…

Next comes the HTTP Get step:

The API expects the following format:

http://api.fixer.io/2017-01-01?symbols=USD,GBP

I use the CheckDate variable from the previous step to get the rates for the previous day.

Now it’s time for the new Pars JSON step, input is the body of the HTTP step.

To generate the schema all I have to do is pasting the JSON returned by the API.

For information purposes I send myself a mail with the relevant data.

The result looks like this.

As there are only new rates for weekdays I’m using a condition in the next step. Only if the date returned is equal to the previous day proceed to the last step.

First I have to define a streaming dataset in Power BI. Again this is pretty straight forward.

In Microsoft Flow I have defined the counter part as follows.

And that’s all. The rates are transferred to Power BI on a daily basis and only for weekdays (see the gap between 03/17/17 and 03/17/20.

One problem remains. I don’t know why but Live Tiles show no data for my streaming dataset. A bug?

So that’s the story so far. On my wish list I have one big point. Microsoft please provide access to the streaming dataset, e.g. in Power BI Desktop or Power Query …
