Yes thx!! Very helpful... Just one remark: To enable this feature, first have to go to the View tab in the Power Query editor and select the Always allow option in the Parameters group.
This was a great and informative video. One thing that I did forget was about not being able to download the PBIX once incremental refresh has been applied. THANK YOU!!!!
i have been follwing power bi courses on udemy , they hardley explain incrimental refresh, yours is much better i was able to understand completely from the first attempt, thank you very much for this channel
Very very helpful Rick. Could you also create a tutorial may'be where you go into the setup of the dataflow/ dataset / incremental refresh. Kinda curious how you link this all together!
Hi, I really appreciate how simply you were able to describe things. What can I do now that my "View native query" option is greyed out and my source is an Oracle database? My requirement is basically that my data changes every day, replacing old rows with new ones. I want to save the old data as well as the new, and I want the new data to be appended to the old.
You may have found a solution by now, but I leave this to the other bypassers. I'm not sure if your issue is surrounded by the Oracle database, but I basically had the same issue with a regular Azure SQL server. I had previously used a SQL statement (with time intelligence) to query the data. I deleted that and accessed the data in the normal way. Then I implemented the RangeStart & RangeEnd to my dateKey and the 'View Native Query' was visible.
Hi Rick, this is a wonderful tutorial. Thank you very much. This topic is not very popular on YT so any further videos on this topic would be very welcome. Thank you.
Thank you so much. I am in the process of redesigning my reports and IR is an integral part of this. This week, I learned that you don't have to have query folding capability in order to implement IR which I thought was the case. You can apply IR to a file folder sourc If you have a set of files with period changes. The other thing is , navigating the limitations you mentioned in your video. Your suggestion of separating Reports and Models is one way to circumvent this which I like. I also have been flirting with DataFlows and you mentioning it makes me consider it as well. One thing missing in your demo is how Direct Query Mode affects this. May be an idea for a followup video? IR seems a very important issue and am wondering why Microsoft doesn't allow it at the Desktop Level.What is your take?Economics or design challenges ? Thank you for all your hard work in teaching us PBI.PQ.
Really great video makes this subject quite simple to seem. I'll try to follow you step by step. If u could comment on "data modification" would appreciate much
Thank you! Very well explained! What if I add a new column do this table? Will it make a full refresh and later automatically incremental refresh? It's because my table is too heavy but we usually have to add some column to it.
Very clear tutorial thanks! In my case I have a plain date column in my dataset. The documentation only seem to cover the cases of a datetime column or a date column of "integer surrogate keys in the form of yyyymmdd". Transforming the date column to datetime inside powerBI leads to query not folding. What would be the advisable course of acrion here? Turn my date column into datetime in my db? Create an extra column with integer surrogate keys? Thanks in advance
Thanks for these wonderful tutorials, I just have a question please, do I need to make sure the dates in my Rangestart and Rangeend meet the max and min date values in my dataset or I can just use any default dates while creating the parameters.
Thanks for the video, in the last case, when you connect to a dataflow that incrementally refreshes, wouldn't the dataset load entirely the data again and again? because the incremental is in the dataflow and not in the dataset?
Hi Rick, and thanks for this video tutorial I followed the steps but I still see "View Native Query" disabled I'm trying to set incremental refresh on Teradata table. Do you have any idea why it is disabled? Thanks in advance
Very helpful video, however I need to add something ( maybe it is because, two years ago native query was disabled in PQ in general ? ) You mentioned about "View native query" option that can not be greyed out, which is not 100% true. It can be greyed out and still incremental refresh works. For example for Databricks data source. Even though "View native query" is disabled, using -> Databricks.Query() function to create a SQL statement with RangeStart and RangeEnd parameters makes incremental refresh works. All the steps in terms of configuration after PQ, has not changed.
Sorry for an info, I hope to receive an answer after setting up the powerbi file is it necessary to upload it to the workspace with the data content starting from the first date? Let me explain better: If I wanted two entire fiscal years is it necessary to download the data locally in my powerbi desktop set the parameters and the incremental refresh and then save it in the workspace? Or can I set everything but uploading for example only the last month and after uploading it to the workspace and launching the first update the file is populated with all the data starting from the first date back 2 years
are you sure it will be faster than the full refresh? Because mine in semantic model and dataflow are the same, they are take longer than then full refresh
Hi thanks for the explanation. I was wondering if my SQL table changes (new column, deleted column, renamed column) and I need those changes to be reflected in the Dataset, how does the incremental refresh handles that or it doesn't and we have to create a totally new power bi file, republish and perform a full refresh ?
Hello, beautiful explanation, I had one doubt on the incremental refresh. I am not ableto greyed out and not able to make it active. please help on the same
I have a question about this. So let's say that the main table that feeds the visuals, is a table that is comprised of an appended table. How would I go about creating the incremental refresh to it? Should I do it with the table of the append, that is changing? Should I apply it to the appended one? Cheers!
Hi Rick, first of all i dont realy understand why I need to filter the data in tables using the parameters. Why is this a requirement? and what if I have multiple fact tables in my model and I would like to have different Start / End Range filters on the different tables. is it posible to make such parameters per individual date tables? if so how, if you can only RangeStart and RangeEnd as the parameter names. Cheers, joris
Hi Rick, how will I set up if I would like to Achieve data 3 years before refresh (1/1/2019 - 3/31/2022) but Incremental refresh from 2 months before refresh until future data (4/1/2022 - 5/31/2025). Because I have some data for the future that needs to be refreshed too?
How to set up this Azure Analysis services ? We are using Visual studio to develope the model and then deploying in Azure analysis service . Everyday we are doing a full refresh and source datasize is more 500 GB from Oracle . We are not using PBI destop to author data model .
When I filter it is not showing me native query but it show in above step. I am getting my data from API from Zappysys through ODBC connection can it be possible to get increment refresh
Are you sure? This is a pro feature set IIRC. I am on the first refresh rn after publishing with incremental refresh enabled, so I should know here shortly (pro user)
Hi Dear, I have power query table called "tbl_1". I need to have another table called "tbl_2" sourcing data at "tbl_1" step no. 4. There are other steps also after step#4. I don't want to duplicate table because it was decrease its efficiency. How can it be achieved without duplicating table?
Is this technique in any way different from this one: 1. Create Table1 that loads data till say 1/1/2024 and set it to not "Include in Report Refresh" and not "Enable Load". 2. Create Table 2 that loads data from 1/1/2024 till today. 3. Append Table2 with Table1
I have an oracle database and getting the table from a datamart as the data is big in size but when I imported the table by using a SQL query, I can't see the (View Native Query) option it's greyed out.. Help?
I have a fact table with start_year (2020) and end_year(2023) parameters in it to limit the number of years worth of data. On top of this I have incremental refresh of last 13 months. I publish this file to web service and change the start_year parameter say from 2020 to 2019. Why does the parameter changes in web service doesn't take into effect? If I change from 2020 to 2021, it does make necessary changes but for the first time only after publishing the file. Any thought on this? My report should only hold only last 5 years of data with last 13 months of incremental refresh.
why is the archiving period from 1st Jan 2019 to 31st Mar 2022... it's 3 years 3 months. Then we have 3 more months of refresh. Can someone help me with how the periods are getting determined here? As I understand if want to have 3 years of data to be contained from the refresh date, Power BI will archive any data from three years before the refresh date to the refresh date. Considering the refresh date in the video is 5/31/2022, the starting date of the 3 year period should be 5/31/2019. This should be a rolling period and the latest 2 months of the rolling period should have "truncate and load" treatment and ten months will be as is. Any data now falling outside the rolling window will be deleted automatically. At any given time the report should contain not more than 3 years of data. Isn't it how is should work?
You said in minute 2:05 that a Date column is enough. However it must be a Date/Time column, a Date type column is not sufficient. Are you sure what you doin man? :)
Actually it is sufficient. I’ve used it many times in practice, showed it in the video and written articles on it. Here’s more details if you need it. datahub.nl/incremental-refresh-in-powerbi/ From the way you write your comment, you don’t seem at all concerned with how you come across. There’s better ways to phrase things.
I think that the name Incremental is misleading. They should have called it partial refresh or something. Incremental refresh is associated more with the ETL process where you detect new/changed records in the data source based of the modstamp table and then insert only the new data/overwrite existing that had changed from last data load (you need unique record id for that as well)
Yes thx!! Very helpful... Just one remark: To enable this feature, first have to go to the View tab in the Power Query editor and select the Always allow option in the Parameters group.
Didn't know that, thanks!
This was a great and informative video. One thing that I did forget was about not being able to download the PBIX once incremental refresh has been applied. THANK YOU!!!!
You're the best, thanks for confirming the naming Rangestart for it to work.

Great video. Thank you!
I have 100 Mln+ rows and 30 columns and dataflow works with problems...
Can't use dataflow(
Why would you want the dataflow? You can also connect directly to your database and use incremental refresh?

My question here is does this incremental refresh work if the data source is a stored procedure?
I’m not sure
This very helpful. Can you do an incremental refresh on a reference table?
are you sure it will be faster than the full refresh? Because mine in semantic model and dataflow are the same, they are take longer than then full refresh

Thanks for the simplicity! This only applies for Import mode right?
Mostly correct. Also for hybrid tables: powerbi.microsoft.com/en-my/blog/announcing-public-preview-of-hybrid-tables-in-power-bi-premium/
@@BIGorilla Can the dataset has some incremental refresh tables type and some are not?
@@JS-ts2vv absolutely, you can specify for which tables to apply it to😁
Really helpful

How to do incremental refresh for scd type 2 tables in power bi
Hi Dear,
I have power query table called "tbl_1".
I need to have another table called "tbl_2" sourcing data at "tbl_1" step no. 4.
There are other steps also after step#4. I don't want to duplicate table because it was decrease its efficiency. How can it be achieved without duplicating table?
Hey! View Native query is disabled for me after filtering :(
Is this technique in any way different from this one:
1. Create Table1 that loads data till say 1/1/2024 and set it to not "Include in Report Refresh" and not "Enable Load".
2. Create Table 2 that loads data from 1/1/2024 till today.
3. Append Table2 with Table1

Thats the reason why you do not use any office products. You have to pay for things you are able to programm yourself.
Why does nobody address whether this wroks with pulling the data from a dataflow? omfggggggggggggggggggggggG
Why did he create parameters
