I watched 2 videos in youtube..... couldn't understand but your video is so precise!! THanks

@SolutionsAbroad 2 года назад

Glad it helped!

@michaelarthurholloway9539 2 года назад

You're using OrderDate both for the RangeStart / RangeEnd filtering on the table, and for the Detect Data Changes field. The documentation explicitly says you shouldn't do this, and that Detect Data Changes should be set on a different field: "This should not be the same column used to partition the data with the RangeStart and RangeEnd parameters." The docs don't clarify why it's a problem (e.g. what will go wrong), but I'm wondering if your example in the video might encounter issues because it's not following this guideline. Thoughts?

That's a great video. Thank you so much for explaining this in detail

@gagandhaliwal40 2 года назад

Hi Fernan, very useful video. I need your advise as facing one issue as I set up incremental refresh but after every scheduled or on demand refresh it is not overridding the parameters. Hence, not able to load recent data instead getting same(OLD) data from RangeStart till RangeEnd. Any solution?

@abcxyz6606 2 года назад

Thanks for showing this. I got M query fold error after apply date filter. any Suggestions on fixing it?

@ianuplask7738 Год назад

Hi , very nice video and informative but I have one question. In case of a dataset , and in table that it’s m query has many steps in which step I had to apply the custom filter? At top after the step is calling the source ? or at the end? I tried the second option and the performance of refresh is 5x worse than before

@paulpham7441 Год назад

Thanks for the video! How do we handle when in my SQL database the table has changed (new column, deleted column) and want to exposed those changes? Does this mean we have create a new power bi file and do a full refresh? Is there a way to avoid a full refresh?

@pankajkumar-pe3zd 2 года назад

Hi, in my query editor i have one main table "Raw Data" linked to the database, i have created one referenced table by using Main table which is named as "RawData2". now for incremental refresh, do i need to follow the process for both the tables or just main table. i am asking this because i believe reference table also taking data directly from database not from the main data.

@berknoyan7594 Год назад

thanks for the content fernan, i have one question which is very confusing to me. some vids on the web says you need directquery / queryfolding to use incremental refresh logically otherwise with import mode your incremental refresh is meaningless. however on incremental refresh page powerbi says "you need import mode to apply incremental refresh" i got confused. could you help me?

@kingsfordgokah6240 2 года назад

Great Video Fernan

@TechEduSphere941 3 месяца назад

Thanks, Fenan for this wonderful tutorial, quick question, will the Refresh button be clicked on Power BI service or Power BI desktop for the incremental refresh to work?

@yogeshmahadnac9426 2 года назад

Many thanks for the very detailed explanation! I have another problem with the Inc. Refresh: storing the last 7 business days & only refreshing the last 1. When the data gets refreshed, it duplicates. Any one has encountered this? Any solution?

@sumitsehgal8805 2 года назад

Hi Yogesh - I had the same doubt watching the video. How will PowerBI know if it's a "new" row or an existing row that got "updated". Did you find the solution to your problem?

@jaguarprovo 2 года назад

I have a staging workspace where I set up a dataflow that imports data from an on-prem SQL Server database. On one table I set up an incremental refresh and it takes 30 seconds to update. In a separate workspace dataflow, I linked to that same incrementally refreshed table. However, it takes 3 minutes to refresh. The linked table has a Referenced table associated with it. Do I need set up an incremental refresh on the Referenced table, too?

@kayalvizhisundaram8448 2 года назад

Hi, Thank you for the video. In my case i am using more than one table in the dataset. in that case do we need to follow the same process for all the tables to setup incremental refresh in powerbi desktop? Also one of my report it uses past 20 years data to show the report values and monthly refresh needed. when i filter the data as you suggest the data got filterered and i am not seeing the needed output.. if it possible to use incremental refresh when we show data in the visual using past 20 years data.

@kayalvizhisundaram8448 2 года назад

Please suggest

@optimaxtb2395 2 года назад

Very good video. The bit I am confused about is how it uses the 'order date' field to limit which rows it refreshes if that order date field only exists after the data has been transformed. For example my dates come in as a number (i.e. 9945684) which I have to convert into date format, so how does it decide if a row needs to be refreshed before it refreshes it? Does it look at the data it has gathered in a previous refresh and use that to exclude which rows are refreshed? Or does it apply the transformations to a single date column for all rows and use this to limit the refresh? Or am I missing something completely?

@SolutionsAbroad 2 года назад

Hi, from what I understand in your question, regardless of how the transformation happens, the incremental refresh will only look at the final result. When you have a running incremental refresh, it will store a date which it uses as cut-off point based on the parameters you put in. which row it updates depends on the date in that "Order date" column and this cut-off period. If the date is outside the cut-off period, i.e. in the past, it wont update those rows with the past Order date. Hope it helps, it sounds a bit confusing, so I'm linking to you an article with some diagram and examples on how this works: docs.microsoft.com/en-us/power-query/dataflows/incremental-refresh

@SanyuktaSuman-um8pd Год назад

Hi Fernan for this awesome Tutorial. I need advise from you. I have a dataset in BigQuery that changes every minute (new rows gets added every minute). The size of the dataset is around 13 GB. I need to find way to refresh my data every minute, but not the whole data set. As far as I understood, incremental refresh setting does not refresh the data every minute. Is there a way I can solve my issue?

@SolutionsAbroad Год назад

Hey mate, it sounds like you'll need direct query or at least composite model to accomodate for this, so you can keep a part of your model refreshing in real time!

@mirrrvelll5164 Год назад

How does this work when your source is on VM (virtual machine server) or Dataflows?

@SajjalBajaj 3 месяца назад

Can I use RangeStart and RangeEnd data type as Date as I have created date as date only? Also my dataset is in import mode and source is mysql db is it possible?

@hemamaleni Год назад

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.

@amyperalt 19 дней назад

I have followed all the steps but when I check the next day it didn't refresh. and when we give incremental refresh to desktop will it not allow to refresh in services?

@ksowjanya4488 Год назад

Thank you for your video. I am new to use this. sorry if it is a silly doubt. I have a doubt, I have csv files in sharepoint folder. where every week a new csv file is uploaded to it. I created a data flow to save one of these csv file data in dataverse using dataflow in dataverse. Now in order to update following weeks csv files, I want to use incremental refresh. to do that we create RangeStart and RangeEnd in dataflow of dataverse. Now how to go to incremental refresh in dataflow in dataverse. Is incremental refreh available only in power BI editor? show I definatly create workspace and datflow in power BI?

@swarajhegde9059 Год назад

Hi bro,you there ? I have a question to ask. So you get new csv files every time right. So do you append those files to the main file and refresh ?

Hi, My "Apply All" button is greyed out.. I can't click it... What could be the issue? Thanks...

@SolutionsAbroad 3 года назад

Hi Mike, I assume all the fields are filled in, the next thing I would check is to make sure that the columns you use are of DateTime type, this is important, otherwise the incremental refresh wont work

@mikedemon6630 3 года назад

@@SolutionsAbroad Thanks for the advice... Also, I found out that I need to publish the report only able to apply the incremental refresh.. hahaha

It would be good, if you can show any data, that was done by incremental refresh.

@pthapa55 3 месяца назад

In order to understand incremental refresh, we need to be able to understand answers to these questions. 1. What is incremental refresh? 2. Why do we need it or what is the benefit of using this? 3. What are the license requirements to use it? 4. What are the draw backs of using it? What are its limitations and such? 5. Which fields are we considering for incremental refresh if there are more than one date field in the dataset? 6. What if dataset has date instead of date time? Will it create an issue? And, there might be more unanswered questions to it which I have not mentioned above on my lists. Thanks
