My data source is Blob storage which is around 270MB of data and is taking around 4.5 hours to refresh. So encountered 120 minute timeout issue on power bi service. Therefore gave a try at setting incremental refresh.
I don't think I have premium license as it shows 10GB storage at the top right hand corner on my Power bi Service. Does this mean that I wont be able to set the incremental refresh?
But I gave a try as below:
I manually created RangeStart and RangeEnd parameters in the manage parameters as below (as there were no default ones), but not sure about the "Current value" field (See below)? So I left it blank and sorted the date/time column according to these parameters
And the next step, while enabling the incremental refresh, the button has been greyed out as below:
Not sure how to proceed.
You are correct. Incremental refresh is a PBI Premium preview feature only.

I'm really confused about how i can refresh data that i use in my powerBi.
The data come from a server in SQL, at first time i choosed to use DirectQuery as importation mode, after a litle bit of time i observed that its took time when i want to change things like measure or representations.
So i opted to change directquery to importation in order to gain time.
I would like to know how can i get the newest data from my sql server automaticly, because i have line which is added every day, would i use accrementiel refresh?
Just set up a daily refresh schedule in the Power BI Service. If you have big data with a long history you might also benefit from incremental refresh, but that's alread an optimization step.
Are you aware of power bi gate way ?
Keep your dashboards and reports up to date by connecting to your on-premises data sources without the need to move the data. (https://powerbi.microsoft.com/en-us/gateway/)
You just need to install power bi gateway to your server.
Then you can visit power bi service -> settings -> manage gateway . You can setup new gateway here.
Once you create connection you can schedule refresh time with your UTC time.
Note: you need to buy power bi pro or premium licence for that. Pro licence has 8 times refreshes per day and premium has about 48 times per day(premium is very expensive) .
And their is feature called incremental refresh, you have to setup it prom power bi dashboard.
It may take 10-20 minutes to refresh data set.(mentioned in power bi site)

When going through DAX overview documentation on the following https://learn.microsoft.com/en-us/dax/dax-overview,
under the Calculated Column heading, I couldn't understand the highlighted information in the following statement:
"(calculated) Column values are only recalculated if the table or any related table is processed (refresh) or the model is unloaded from memory and then reloaded, like when closing and reopening a Power BI Desktop file."
Does it mean, that whenever we close the Power BI Desktop file, the model is unloaded from memory? does the memory is used like Cache?
Would anyone please help me understand what actually happens in practical world? Thank you for giving your valuable time and support!
The main point of this remark is to distinguish the difference between measures and calculated columns since the distinction is often not clear to report builders.
A measure is dynamically calculated on-demand when the end-user interacts with the report via slicers or any other sort of filtering and interaction.
A calculated column is only calculated when the model is refreshed. As a result, calculated columns cannot be dynamically responsive to the end-user since they have already been computed before the user can interact with the report.
Power BI Desktop is excel on steraloids. It is an application and as with every application when you close it, it unloads from memory. Its great and you can do a lot..
It has the option to refresh (a button) when you press it, it recalculates your calculated columns.
If you want dashboards and reports served, to be shown in other (web) applications. You want to go with Power BI server. It runs in the cloud and you can refresh the data (daily, on the hour or direct) you can set this all up scheduled in the admin tools.
It is logical that only on a refresh, your calculated columns get recalculated. Only in this moment of time your raw data is changing what will have effect on your calculated columns.
I haven't done any changes in my dataset for a while and in the past few days, the refresh and publish features (via PBI Desktop) were working just fine. However, this morning, it suddenly stopped following through the scheduled/automatic refresh which were set 5x a day every 2 hours starting 8AM. When Itrigger manual refresh, it says "Preparing for refresh" but doesn't really follow through with it, so i kept on clicking it but to no avail. After a while, I checked the Refresh History and the error I got was it's timing out.
I was trying to republish it with a newer version which was the same dataset refreshed in a different workspace. Apparently, when I publish it to a different workspace, or if I rename it and publish it to my existing shared workspace, it works. BUT I don't want to push through with this kind of workaround because I cannot afford to redo my the set up of RLS and manage permission in the dataset of my existing workspace.
Hope you can help me on this. Thanks.
Try signing in to the workspace using a browser, then use the Get Data feature (arrow button at bottom left), then choose Files / Local File and select your PBIX.
It's effectively the same results as a Publish from Power BI Desktop, but sometimes the method above works when Power BI Desktop is jammed up.
You might also have a refresh issue, not a publish issue. There's an unannounced-refresh-on-publish feature that most people don't notice:
"When you republish a dataset published from Power BI Desktop and have a refresh schedule defined, a dataset refresh is started as soon as you republish."

I have Power BI report which is connected to the dynamic 365 to show the report of contact and account but the data set has more then 2 GB of data and I am not able to publish the report.
how can I decrease the size of the data set so that when publish I can refresh and update data set to get the 2 GB of data.
I am not able to publish the report
one thing which I used to take the top 100 rows by using one of the option in the Data Set but when I refresh the data set after publish it get top 100 record
A .pbix file has no size limit, but PowerBI service has a limit of 1GB (for a pro subscription) per dataset, higher-level subscriptions (embedded/premium) have higher limits.
Unless you can upgrade your subscription (which may not be worth it for one report), you have to decrease the report size.
The suggestions are always the same and can be found on MS website, I had a look at it and I have nothing to add.
Below the points that you will find on the MS website, in case the link stops working:
Remove unnecessary columns
Remove unnecessary rows
Group by and summarize > pre-aggregate/aggregate data, with the detail you need
Optimize column data types > chose the right data type for each column
Preference for custom columns > create custom columns in PowerQuery (M), they have a better compression rate compared to DAX calculated column
Disable Power Query query load > do not load tables you don't need (support table used for calculations but not needed in the model)
Disable auto date/time > disables the calendar hierarchy created by PBI for each date in your model
Switch to Mixed mode > This mode is a mix of import and direct-query, you will find more info online about this. (if you choose this have a look at the aggregations functionality)
I am looking at retrieving data from an API in Power BI.
I would like to avoid processing all of the data again when I run a refresh. Is there a way to add the new data to the existing data in the dashboard as a delta upload instead of a full refresh every time?
Thanks for any help.
You need to buy Premium for this. Power BI Premium supports Incremental refresh (see announcement and documentation).
With Incremental refresh you define two parameters, RangeStart and RangeEnd, and policies how to refresh the deltas. The values for these parameters are managed by the service. Then first refresh will be slow, because it will load all the data, but next refreshes will only load the data for the period after the last refresh.
