I have an SSAS Tabular model composed of a fact table and 3 dimensions.
I want to understand what is the difference between creating the relationships in the tabular model in advance comparing to import the tables or using a direct query and then create the relationships in Power BI ?
If you DirectQuery to SSAS Tabular, then the measures and relationships should already be included.
Power BI essentially is SSAS Tabular under the hood, so the calculations should be the same whether you build your model in Power BI Desktop or SSAS Tabular. The difference is where you're running it. If you have SSAS Tabular on a strong server, DirectQuery might be faster than running the computations locally in Power BI Desktop.

Is there an easier way in Power BI to repoint the visuals to a new table which initially pointed to another table?
Scenario :
I have a Power BI report which is sourcing data from an Azure Analysis Service. The AAS model has multiple tables out of which 2 had issues and had to be re written with a new logic. Now the main task is to repoint the visuals in PBI to fetch fields from newly added tables.
The one way I know in this scenario is a manual effort where you replace/switch fields in visuals from old to new table.
Is there any better/easier/efficient way to achieve this?
TIA
I want to know the difference between implementing RLS or DRLS in SSAS vs Power BI.
If we are implementing it in SSAS tabular should we implement it in the Power BI also ?
We are using an SSAS tabular cube as a datasource for our Power BI report.
If we are implementing it in SSAS tabular should we implement it in the Power BI also ?
No. RLS is implemented in the tabular model. If your tabular model is hosted in SSAS, and your Power BI uses Live Connect mode, then it will use the RLS in the Tabular Model.
I have a requirement to produce some PowerBI reports. I have three different SSAS Cubes having most of the measures already available/calculated. So I want to use these cubes as source for PowerBI. But there are few calculations those need measures from different cubes. PowerBI does not allow to create measures with live connection to Cubes. Also due to data volume import is not the feasible solution.
I am looking for a possible solutions for this problem please. Please suggest.
It should be possible now to connect to multiple SSAS sources now using DirectQuery and a composite data model.
I recommend these articles for an overview:
DirectQuery for Power BI datasets and Analysis Services. The composite model with Analysis Services. What is it and why it is a big deal?
Power BI Composite Models using Analysis Services -Direct Query Mode
I have a SSAS tabular model I have deployed and made some power Bi reports. now I need to add some new columns and measures to SSAS and also add them to power BI. How I can do that?
As Power BI connects to SSAS Tabular in Live Connection Mode, once you update the Data Model and deploy it, open Power BI Desktop and it should see the changes made on that connected SSAS Data Model. You can then update and publish your Power BI reports to the service so the new metadata takes affect.
Anything that you remove that from the Data Model, may introduce broken visuals and errors, however adding anything new that isn't yet used will not affect the visuals or reports.
I am new to Power BI and trying to build a report for one of our business requirements. I have access to a Power BI dataset which I imported in the Power BI desktop version. I also need to import an excel file placed in SharePoint/OneDrive and merge the data in these two sources. When I am trying to do this, I am getting the below error.
Is this feature not available in Power BI?
If not, is there a way to achieve this objective?
You are connected to a Tabular SSAS cube or Power BI Service dataset, you can't add other data sources.
You can only mix data source types in the modes direct query and import. See the limitations section of the MS docs
One option would be to recreate the Tabular data model in Power BI, over the base table/views it is based on in direct query mode, then add the SharePoint list, or add it as a table in the Tabular/Power BI Service Dataset
