So I'm working in creating a dashboard the refresh everytime a user set up s new parameter.
The SQL query that I'm running on running on a direct query load is the following:
select * from dbo.userHistory where userid = jop1320
The table mentioned above has multiple millions of rows and I want to filter the dashboard dinamically when an user change the userID.
I've went over and created a parameter for this and the code in power bi will look something like this
select * from dbo.userHistory where userid = '"&userid&"'
Now my question is, instead of the user going to transform data and click on edit parameters, is there a way that I can create a visual for the user to pass the userId that he wants to filter and then refresh the dataset?

I am trying to run a direct query on my DB and apply a filter input by the user. The user input would be used as a parameter for my Stored Procedure that retrieves the data I want to display to the user. The reason for running a direct query and not just refreshing the data and then the user filtering from all of that data, is that the database is really large and it would make the report file approx. 650mb in size. My idea is that with a direct query, I can pull only the data required through an indexed column that the Stored Procedure uses to filter.
Currently I was able to create a parameter in the Query editor and use it in a query function but this creates an "Invoked Function" table. If I use these results in my report essentially the user can only filter through the result I filtered in my query editor. I want the user to be the one to input that value and the report to dynamically load it.
As far as the filter field, I am using a slicer and added the search capability to it so they can type out the search value and select the result in the list. Ideally I would like a textbox that they can type the value they want and search for it.
Is this possible in PowerBI? and if so how could I accomplish this?
You have to download a separate application called Power BI Report Builder to accomplish this and create a paginated report. See Url below:
Paginated Reports
I have the following requirements:
The user will see a Power BI Matrix on a web page (as opposed to Power BI Desktop).
The web page should have three elements: a text field, a button and the Power BI Matrix (potentially included in a Power BI Report).
The user will enter the DAX statement in the text field and click on the button to direct the Matrix to take the DAX statement, execute it, and populate the data.
The user should be able to drill down in the Matrix.
The user may reenter a new DAX statement, refreshing the Matrix.
Now, all the documentation I could find, for example here, talk about the Matrix in Power BI Desktop (i.e. not web page) and the data taken by selecting manually tables/columns/measures (on the right side of the screen).
In Power BI Studio, I know that I can enter a DAX statement by creating a table in the top bar, for example if I have the DAX:
EVALUATE TOPN (3, branches)
I could create a table to populate the Matrix with:
BranchesTable = TOPN (3, branches)
But how to dynamically link a DAX statment defined at run-time to a Matrix on a web page?
This is not currently possible to do exactly what you want. You can dynamically change a data source and update the query used in a specific report but there isn't an API available (PowerBI REST or PowerBI JavaScript) to update what columns are on a visual in a report. You can get pretty close to what you want but the report cannot be displayed in View mode and it will have to be displayed in Edit mode so the user will have the ability to drag the fields generated from their updated DAX query results onto the Matrix visual manually if they submit a change.
Assuming you already have the pre-requisite App Registration setup and configuration completed and your ready to embed here are some steps to get close to what your looking for. If your not ready to embed there is some documentation below the 8 steps I provided to complete the pre-requisite setup to be able to embed.
Using PowerBI Desktop Create a template report that has a matrix visual and a connection to the data source you want to use. Be sure to set this report up using a specific query and NOT all tables in the data source whether its SQL or SSAS. (You specify the query under advanced options when you initially setup the data source in the report)
Setup a Power BI Data Gateway to the Data Source your report uses
Create a workspace on PowerBI.com to upload the report to
Using PowerBI desktop Publish the report you created in step 1 to the workspace you created in step 3
On your Web Application, when a user views the report viewer page, you need a way to identify each user. Lets assume you have UserId field that is a unique ID for each user. Call GetReports in group https://learn.microsoft.com/en-us/rest/api/power-bi/reports/getreportsingroup. You need to have a known report name plus the UserId. Lets assume its DynamicReport. So call GetReports and check if DynamicReport_UserId exists for the user trying to view the report viewer page in your web application.
In that API calls result from step 5, if the report does not exist for a user, use https://learn.microsoft.com/en-us/rest/api/power-bi/reports/clonereport to clone the template report you published in step 4.
Embed and display user specific template report (DynamicReport_UserId) for the user.
Have logic on the report viewer page so the user can submit and POST a DAX query. When they do a submit have logic to use https://learn.microsoft.com/en-us/rest/api/power-bi/datasets/updatedatasources on the back end to update the data source in their report and then embed the report again with their DAX statement and changed data.
The visual isn't going to automatically update to the new fields from the new query that is submitted by the user but the available data fields they have in editor mode will change. The user will have to drag and drop the fields from their DAX query onto the Matrix visual or whatever visual type they are going to chose to use. You won't be able to just display a report in View mode since you don't have a way to programatically update what fields are on visual. The user may even end up seeing a broken visual initially because of the changed query and the visual referencing fields from the previously used query. You could use PowerBI Javascript API to hide the existing visual to improve the user experience of the user not seeing something broken.
Let me know if you have any specific questions about these API calls or how to use them.
Here is where I've been looking for the Power BI JavaScript functionality https://github.com/Microsoft/powerbi-javascript/wiki (Can't find anything specific to matrix Visuals. The JavaScript functionality for visuals generic to Visuals and not Visual Type like Matrix or Card)
Here is Microsoft's documentation on the available REST APIs and https://learn.microsoft.com/en-us/rest/api/power-bi/
Here are some good resources to learn more about embedding
https://learn.microsoft.com/en-us/power-bi/developer/embedded/register-app

If you need drill down capability Hierarchies are a great option

I have one Power BI file that needs to be embedded in the Power App Portal using Power BI embedded code (iFrame code). I am filtering the iFrame code by applying query parameter filter in the Embedded URL.
The issue is that the value of query parameter can be changed by any end-user who is aware of the value.
For example, if we are passing user id in query string, another user id who knows the values can also change the user id in the same query string.
My question is how to securly pass the parameter in the P-BI embedded? Is there any special encryption method so that the parameter value is encrypted at end user to avoid changing the user ID
You need to implement RLS (Row Level Security). That way, users logging in to view the iFrame will see only data he is supposed to view. You will have to configure roles in power bi-level to determine how data access is determined for each user.
Read This to find out more about RLS.
We currently host data for multiple users in our database. I'd like to implement embedded power BI into our web app. When the user logs into our system, I'd like the data source to be filtered according to the user that is logged in, so e.g. SELECT * FROM Table1 WHERE ItemID in (ItemID1, ItemID2) etc..., we aren't going to know what ItemID1, ItemID2 etc... are until after the user has logged on.
Is this possible with PowerBI embedded?
To filter data for Power BI users based on which user is logging in to the embedded web app, complete the following:
Sample:
Create a table to store the usernames for each filter "group."
You will use DAX to create a measure to identify the users from your table, and assign them to a specific user role group. Below is the DAX to use:
[USERNAME] = [Current User]
Create the measure described in point #2 in the Row-Level security settings. By creating different "groups" for the users, you are essentially dynamically-building a "filter," where you only show the users what they should be seeing--thus resulting in pseudo-filtering. For more information see the following:

I need to show data only for logged in user in PowerBI. He is manager and in drop down i want to show list of employees under him. Also, only load for all employee whose manager is logged in user
We have more than 1 million rows for a day, so I want to hit database only for logged in username, Also, date parameter will be used from UI.
let

Are you viewing the report in PowerBI.com or using an embedded view of PowerBI?
From your question i assume you are using direct query, when using direct query to SQL Azure, you can get data filtered on the SQL server level using single-sign-on (as described in https://learn.microsoft.com/en-us/power-bi/service-azure-sql-database-with-direct-connect), this is only supported for SQL Azure, and only when using PowerBI.com (not PowerBI embedded).
Alternatively - you can switch to imported data (and refresh the data upto 8 times a day), this will allow you to set row-level-security on the dataset using PowerBI desktop (see https://learn.microsoft.com/en-us/power-bi/service-admin-rls)
