Power BI Column Mapping does not show the values - powerbi

I am a newbie to Power BI, I am trying to learn how to create a workflow. As a first step, I created an ADLS Gen2 container and uploaded a sample json to the container. Json has only one key/value. Something like
{ "DOMINO_API_KEY": "val1"}
I am able to establish the connection to my container through Power BI, transform the JSON to a table like in the below screenshot
Then I clicked next to create the Map table. It shows me to enter the table name etc
When I created the table, I do not see the value in the table which I transformed earlier. What am I doing wrong here, can anyone help?
Thanks,
Tintu

Materialized view on firebase events data in big query

I have a table in bigquery which fetches data from my firebase events analytics. The table is made in such a way that it appears to create a new table based on the date. But inside the databaseUI it appears as a single table. It changes when I click on it.
For example: Today's table name would be ‘tablename’_<today’s date> and when I use the filter option available in the big query UI for this particular table type. The name changes to ‘tablename'_'selecteddate'.
I want to create a materialized view on the complete/ combine table of all dates. Not just on a table with a particular date.
How can I do it? Can someone please guide me?
The columns I want in Materialized View is even_date, event_name, event_params( key and value) , count of event_params (of key and value both).
I am unable to find a way. So is it possible?
Thank you

How to add calculated column to PowerBI datasets

I have created a dataset in Power BI web, and then imported it on Power BI desktop (using File -> Get data -> Power BI datasets).
I don't see a way of adding Calculated Columns. Does the dataset need some special configuration to enable this?
Based on my experience you won't be able to see the columns because it using direct query. you can still add some columns and measure but your'e basically flying blind. you can just select the table in the report(visual view) and add column however you'll have to play the guessing game. But if you know your dataset you should be fine.
However a Dataflow wouldn't give the issue you're having.

Missing Column in Power BI Service

I have been requested to add another column in a dataflow in Power BI and have done so and refreshed the dataset which uses the dataflow. The field is not appearing in the list of fields in Power BI for some reason. I have tried downloading the dataset on my desktop and cleared the cache and did not work. I opened Power Query (Transform data) and the column exists. I've tried to refresh preview and Close and Load but still not showing. I have 3 columns in that table in Power Query but only 2 are shown in the list of Fileds in Power BI.
Please can you help?

Power Query
I was able to sort this out by right clicking the table and selecting Refresh data
check whether the data source path is correct or not in PBI desktop [path is from your local machine or not]

How to modify a dataset's dataflow in Power BI?

I have created a data flow.
Then created a dataset that uses the dataflow as data source.
Then I tried editing the dataset to a point to a different dataflow, however there isnt an option to change to a different dataflow.
How to modify a dataset's dataflow in Power BI?
The M code genderated when loading data from a Power BI Dataflow looks like this:
let
Source = PowerBI.Dataflows(null),
#"Long-Workspace-Id" = Source{[workspaceId="Long-Workspace-Id"]}[Data],
#"Long-Dataflow-Id" = #"Long-Workspace-Id"{[dataflowId="Long-Dataflow-Id"]}[Data],
#"Sample Data1" = #"Long-Dataflow-Id"{[entity="Sample Data"]}[Data]
in
#"Sample Data1"
With ID values that look like this fake ID string: 68920386-482d-445e-9725-839065646dde.
So, you just need to figure out the ID values for the dataflow you do want to connect to and swap them out.
One way to find these IDs would be to connect to the other dataflow in another Power BI instance and copy the values from the query editor in that one over to the original Power BI instance.
The IDs are also contained in the URL when you navigate to the dataflow within the workspace that it lives in. The URL looks like
https://app.powerbi.com/groups/long-workspace-id/dataflows/long-dataflow-id
