Faster SharePoint folder consolidation using Incremental Refresh (see warning in the notes)

[@AccessAnalytic]

⚡⚡ Enabling incremental refresh means you will not be able to download the file from the service, so keep hold of that PBI desktop copy ⚡⚡ Always take a look at the description for these sorts of updates

[@zzota]

This is just what I need. I thought Incremental Refresh was only applicable to SQL datasets, so this is brilliant. Thanks Wyn 🙂

[@AccessAnalytic]

Same here… wish I’d known sooner 😀

[@jawadahmadehssan6251]

I went from 6 min to 8 seconds. Thank you. Can we set up a something similar for data flows?

[@AccessAnalytic]

Yes, but needs PPU or P1 ( or F64 I think ). 10:56 shows brief pop up of where to click to enable for dataflow.

[@JorgePerez-bu4ph]

Great video as always. I got confused about something: The "RangeEnd" parameter... Am I supposed to change it manually for the next update or will it automatically update to the last date found in my data files? How does it work? I want to understand if this RangeEnd parameter is something I have to maintain, or if once the incremental refresh is set I can forget about it? Thanks!

[@AccessAnalytic]

Set and forget. It gets overridden by the date of refresh each time.

[@JorgePerez-bu4ph]

@@AccessAnalytic Does it matter at what step the "DateRange" filter is applied? I did it immediately after the source step, after that I have multiple steps adding and removing columns and applying some other data-cleaning transformations. It did not work. I received a bunch of new files during the weekend, all stored on the same SharePoint folder. I followed your instructions the latest files were not added after today's refresh. Changed the RangeEnd manually and it worked. I'm importing data from PDF files and using the file creation date as my date column. What could possibly be wrong?

[@AccessAnalytic]

@JorgePerez-bu4ph - I don’t think it matters. As long as the column is date time type. This is new to me so I don’t have too many experiences to help here sorry.

[@gopichand5717]

As usual great video😊

[@AccessAnalytic]

Thank you

[@samirvaghasiya9918]

Thanks :)) Very informative

[@AccessAnalytic]

You’re welcome.

[@iiiiii-w8h]

please can you show us this for dstaflows? I'm pretty sure I have a PPU licence assigned by my company but I've never used any of it's capabilities

[@AccessAnalytic]

I briefly show where you have to click at 10:56 in the screenshot that appears. Same process, but requires PPU or premium capacity as you say you may have ( workspace settings assign to PPU )

[@mjb4365]

Is this also available for Excel PQ, or just Power BI?

[@AccessAnalytic]

Just power bi sadly.

[@mkcorrea]

Pretty nice! Some really big data we can also segment by generating files with that segmentation and naming it for filtering when consolidating from the SharePoint folder. That will enable solving a demand I have at my company. Thank you so much!👏🏻👏🏻👏🏻

[@AccessAnalytic]

You’re welcome

[@SergiyVakshul]

Wyn, I’d like to add that if a file name points to the future date, then this file won’t be processed during the refresh time. Another important point is what is considered to be the current date. I mean that the specified time zone for the scheduled refresh can shift your date one day, which may impact the result (the docs cover this aspect).

[@AccessAnalytic]

Good points. Thank you 🙏🏼

[@LukasMissias]

Excellent video! Is it possible to apply to Sharepoint lists?

[@AccessAnalytic]

Thanks. I don’t know sorry.

[@LukasMissias]

@@AccessAnalytic Obrigado pela atenção 😀

[@aigbekennethomorodion4026]

Does incremental refresh now work on data sources that don’t support query folding? Just curious or maybe I have missed something in any new Microsoft updates.

[@AccessAnalytic]

I think this non query folding technique is limited to SharePoint and Azure Blob storage (maybe there's other storage locations too )

[@zorankrekic3006]

Simple and nice when I have new file, what to do when new data are append on last file, and is possible incremental refresh set into dataflow

[@AccessAnalytic]

If you set the incremental refresh period to be a couple of months then any updates to files falling in that time period will be pulled in. Dataflows does have incremental refresh but requires premium / PPU

[@kiasca3489]

Thanks really helpful, is it possible to do it on power query excel, so it doesn't load again the data when refreshing power pivot?

[@AccessAnalytic]

Sadly no

[@suheilsamara7955]

This is Brilliant! Issue is that my file names do not include indication for the date thus the options I have is either to use the date created or date modified columns. What are the concerns in such approach ? I rather think that using the date modified in safer than file name because if I rely on the file name while the content is modified for any reason, such changes won't be picked by the incremental refresh. Agree!

[@AccessAnalytic]

Potentially a file can be opened at any point and the modified date may change ( especially if opened online ). Just safer / more deliberate using file name date.

[@StephenBrincat]

Excellent, one question would datetime like 20/08/2024 00:00:00 work? I mean time will be always midnight.

[@AccessAnalytic]

Yep don't see why not

[@woliveiras]

Amazing video. Thank you. Incremental refresh in PowerBI is crazy. How Microsoft can make something simple becomes a hard thing. To me it is not clear what is the best parameter to choose if I wanna add just the current day in my dataset. And why I would update the entire last month(for example) if this is an incremental refresh. I already added it in my previous update. Do you understand my point?

[@AccessAnalytic]

Yes it’s taken me a while to understand. So if you’re not concerned about previous days data ever needing to be updated choose daily (1 day) for incremental refresh window. ( maybe consider 2or 3 days in case some error is spotted ) Then for historic storage you could do annual or monthly - doesn’t really make much difference.

[@okmr7706]

Hi Wyn, I have 2 qutestions: 1. What happens if current time is beyond RangeEnd? Should I adjust the value of RangeEnd to a future DateTime? 2. I guess this is only work for "consolidateing Excel files" on SharePoint Folder NOT for importing individul Excle file by Web? Thank you Wyn, great video again!

[@AccessAnalytic]

This is only for consolidating files. You can’t forward look range end. What sort of scenario do you have in mind where a future dated file is added on a regular basis?

[@munawarhussain1400]

I have completed the setup. However when I publish a file with increamental refresh and then I goto schedule refresh it show error in refresh. Error is "column Debit is not available" although column is available in dataset and there is no error in BI Desktop . However when I turn off increamental refresh then publishit again, then there is no such error. Any Idea how I can solve this?

[@AccessAnalytic]

That’s a new one to me, not heard of that before sorry.

[@Bhavik_Khatri]

Thank you for the video. Can you please share the files, too?

[@AccessAnalytic]

You’re welcome. There won’t be much point as the query will immediately error as you won’t have access to the source files.

[@shidubravinarunasalam1995]

Hi is this option available in Power BI Desktop-On Premise, i couldn't find this option while right clicking on the table, i have done this following steps, what you have done, but the option is not available in Power BI Desktop-On Premise, but if i open in Power Bi Desktop Cloud i can do this process, but again during uploading the huge file to cloud not possible, since i have Power BI Pro License, any other suggestion from your side?

[@AccessAnalytic]

I’m not familiar with power bi desktop for report server ( I assume that’s what you mean by on-prem ). I know it’s limited in functionality compared to standard desktop

[@shidubravinarunasalam1995]

@@AccessAnalytic Yes i mean Power BI Report Server.

[@marupbi]

Amazing Job🔝

[@AccessAnalytic]

Cheers

[@AshishSingh-tw2vd]

Great content sir ❤ The only problem which i am facing whith this is the dates . It would have been much better if you could have just explained the purpose and roles of all three dates(one which is parametrized, archive data starting and incrementally refresh date) as well.

[@AccessAnalytic]

Thanks. Not too sure what you mean sorry.

[@data-made-simple]

Great timing - I’m up to 30 mins refresh time on one setup and been putting off looking into incremental refreshes. Explained clearly and simply as usual. Thanks for your videos- it’s really helped using SharePoint folders as quick non code approach over alternatives.

[@data-made-simple]

What about refreshing back dated files - eg an updated sales file from 2022? Assume there’s a choice between incremental refresh and full refresh?

[@AccessAnalytic]

You're welcome - glad it helps

[@AccessAnalytic]

@@data-made-simple - good question. Simplest approach is to do a refresh in the desktop file and re-publish.

[@AccessAnalytic]

If you have Premium you can get fancy with XMLA endpoints and just refresh particular partitions (apparently 😀)

[@data-made-simple]

Ah ok got it. Thanks!

[@RonDavidowicz]

Is there an equivalent for Excel?

[@AccessAnalytic]

Sadly not

[@FahadHameed-uq5zg]

Can you show in little bit easy understable wayy this is too much complex sir.

[@AccessAnalytic]

I tried my best to make it as simple as possible. Is there a particular part you’re struggling to understand?
