Is incremental refresh possible
Hi guys,
Long story short,
I open all excel files from SharePoint folder ( names of files are in date format 2022-10-10 and being added as a column to the table)
As amount of files is growing, how can I reduce load time, so only latest file/or recent files would be loaded?
( I want to keep all existing data in my dataset)
I thought of incremental refresh.
My understanding was it could work where we have some columns with dates. Would that be applicable in my case where only date is newly created column based on field name?
Hi MasterSonic ,
Refer this document, By using additional custom query functions and query logic, incremental refresh can be used with other types of data sources provided filters based on RangeStart and RangeEnd can be passed in a single query. For example, Excel workbook files stored in a folder, files in SharePoint, or RSS feeds.

Hi,
In Power Query, right click and uncheck "Include in Report refresh" to stop file you don't want to refresh more
Hi there,
In my case I have just one table here. I invoke custom function so all files from folder are transformed and appended at once.
