What role does the "Manage parameter" plays in storing the historical data from the "Incremental Refresh"? Because in the custom filter , I have chosen the parameters option to select only one year of data between "RangeStart" and "RangeEnd" , and loaded in the model whereas in the Incremental refresh I have prompted to store data for the last 5 years? So how does the "Manage parameter" and "Incremental refresh" interact? TIA !!
Very informative video. Can you please make a video on " how to handle deletion in incremental refresh on power bi". I know in RUclips have some videos on it but I like your way of teaching please create a video on it ASAP. I will be very thankful to you. God bless you Regards.
Hello Sir can you please explain about why we need to create range start and range end parameters what is used of that and can we choose any random date for that parameter as we set set all parameters in incrimetal in incresmental refresh ther we set archive year as well last days to refresh but i I'm confused as we created these things in incremental refresh then why we need to set range start and range end parameter and is there is relation about this parameter or we can take any date for creating this range start and range end parameter
Both are different things. We use incremental refresh when we have a huge volume of data, and this helps us to limit the amount of data we need to refresh while schedule refresh is just to refresh the data. However, if your data size is huge, you need to implement both.
Hi, can you please help me with "query folding"? Sorry I don't understand this. Just would like provide you some more info on my existing work environment. We are using ODBC to connect live data. Thanks for yr help.
My data is published to powerbi service. The measures work fine in desktop, but after second refresh, I have incremental refresh setup, my measures are not calculating correct totals. Any ideas?
Sir u give one date in range start and range end and again in incremental refresh u given historical+incremental, wts the difference between that date and this date?
Range Start and Range End dates are to apply the policy. Please read more here and if you are still not clear, kindly let me know: learn.microsoft.com/en-us/power-bi/connect-data/incremental-refresh-overview
Hi, I am facing an issue, I've applied incremental refresh on my report and after updating few records I can see that those records are not getting updated instead they are being "Added" in the service. Not sure why it is happening, can you provide the some insights?
Hi, Incremental policy works that you have setup as a policy. For example, suppose you have setup an incremental policy to keep 3 years past data. Then it would automatically keep last 3 years data from today. Also, data before last 3 years would get automatically deleted while new data would be added. That means suppose last month you setup this policy. So, your time frame would start from today. It would automatically gets shift by one month.
Hi, I am facing an issue, I've applied incremental refresh on my report as you've shown but in my report for example , the total number of records are 10,000 and after publishing the report on service, it is all good then I go to the SSMS and in the database I update 20 records and when I come to the PBI service and refresh my dataset and then when I check the count of records it shows "10020" ! So my question is that why the records are getting added instead of getting updated? I only want 10000 records and it should include those updated records and want to replace the old records in the service. Can you please tell how can I get that? I have tried every thing you showed in video and also detect data changes didn't work.
Well, incremental refresh always considers the updated records only. It should not happen. I suggest you yo try again. However, I am going to publish another video on incremental refresh next month and there I’ll address this issue.
Hi mate, Question around incremental refresh. We have actuals and budget in one table (probably not ideal), I've setup incremental refresh. It filters to the current day. I've setup incremental refresh and got effective date to work. But the effective date drops off after each daily refresh. How do I get the effective date to stay on the partition? Im using SQL Server Mangement studio. thanks
Incremental refresh means the first time you are going to load all the data and later on, you will just refresh a part of the data. For example last two months or last two days only! As the date would move, the data refresh date would also move. However, schedule refresh means to schedule it means to refresh your dataset at a particular time. For example, daily at 11 am. Incremental refresh is a part of schedule refresh only!
I'm reading on the MS website that the column for the data changes detect may not be the same as the column where you do the partitioning. Can you explain why it would not be a problem (because you do take the same column) or when it causes a problem? great vid btw!
No idea.. I haven't face this error. Probably if you can share the snapshot or more details, I can have a look. Please do share at connect@biconsultingpro.com

Hi, Very informative video, But I have a doubt in the Incremental refresh option where we are setting up two data parameters, 1st for Store rows and 2nd for Refresh Rows: 1) Suppose we are currently in July 2020 and I want to retain data from 1 Jan 2020 to 31 May 2020, so I write the last 5 months in the store rows option. Also, I want to refresh data for June 2020, so I select 1 month in the Refresh Rows option. Finally, at the end of Incremental refresh, my overall data set will contain data from 1 Jan 2020 to 30 June 2020. Now, when I will run this code again in Aug, then I want data from 1 Jan 2020 to July 2020. But will running the above setup again, give me the desired result or I will end up with data from 1 Feb 2020 to 31 July 2020. Is it possible to fix the starting date of the data set and refresh data only of the time difference that has occurred since the last refresh? 2) Does this data refresh work like Append data, i.e. in the case, the data does not exist for the duration mentioned in the Refresh Rows option in the Power BI data set, then will get appended last 1 month data in the existing dataset?
Hi Kartik, Incremental refresh would keep your data since when is your start date and on each refresh, it would add data for the last time period which you have defined in your increment policy. In this case, data would also start from 1/1/2020 and will end till your lastest data refresh date. However, the dataset won't refresh entirely except for the policy that you have defined. For example, if your increment policy is of the last 30 days only, then it would refresh or add the last 30 days' data only. The rest of the data would be as it is from the beginning even if you have updated data in February 2020, it won't change it. It would be the same as it is as it's not under your refresh policy.
@Kartik In Addition, I would like to suggest something here. Suppose initially, you set up your data for the 5 months to store and refresh for the last one month. In this case, data would get a store for the last 5 months only, and no need to get a refresh the last month's data as it's the very first time. However, next time onwards, you will still be able to see 5 months data but the very first month would get drop to let's say initially it was from Jan - May. Now, In June, you will get data from Feb to -Jun, and your Jan Data partition would automatically get dropped out. Also, only June data would get refresh but others. Also, it won't append anything. However, partitions from the stacks start dropping out like say from the bottom and will add new on the top of it.s
You can change the number of records at the bottom of your screen. Click at the left-hand side bottom of your screen in Power Query and then you can see all the records.
Ideally, there is only one refresh which is known as "Schedule Refresh". However, to refresh a dataset, we can do in different ways. Incremental refresh is a part of schedule refresh only where you refresh a part of the data rather than entire data.

Hi: If you give 5years of data to store and 20days data to refresh. Does the refresh bring data from source of 20days Or of 5 years. I have huge fact table of more than 50million rows, if I setup incremental refresh to store data of 2 years and refresh data of 1 day, still it fails with pro license saying breach of 10gb uncompressed data.
The first time, it will load all the data but going forward it would depend on the "Increment Policy" that you have applied. For example, if you have applied to refresh the last 20 days or 1-week data, then every time only the last 1 week or 20 days data would get refresh only, NOT the whole dataset.
@@learnData-oo5yk Well, if those rows are coming under the refresh data policy, they would be gone in the next refresh. For example, suppose we set refresh policy for the last 2 days and some user deleted data from yesterday then in NEXT refresh, those won't be there. However, if the use of deleted one-month-old data, then Power BI will keep. In incremental refresh, Power BI always drops data from the last which means Suppose, our incremental policy says, keep a record of the last 60 days but refresh data only from the last 2 days. This means every time, data get refresh, your refresh date would be "End Date" and "End Date - 60 Days" would be your start date of keeping the data from 60 days.
Implemented incremental refresh direct query. Data is updated from inprogress to completed state source side inprogress values only available once order is closed or completed state source side order deleted. But incremental direct query partition data. Deleted or available please confirm
Incredible, i hv half million rows in PQ needs to work out only last 2 weeks data.
Its impact drastically on timings.

This will work everywhere provided your connector does support query folding.
