Re: Slow refresh of SharePoint list data

I am very new to Power BI and am facing a similar issue and don't know where to try and use the buffer.table step.

 

I have a sharepoint site that currently contains 562 files with multiple rows of data, each week the number of files grows each week (up to 300 per week).

 

It can take up to 20min refresh data now, so I can imagine it will only get slower as the number of files increase week over week. This behavior only appears to be an issue with connecting to Sharepoint. I tested with the same dataset on One Drive and there were nowhere near the latency issues - unfortunately I have to use Sharepoint and would love to be able to speed up the refresh time.

 

I saw other blogs suggesting to uncheck "Auto Date/Time" but that didn't seem to make any impact, so I'm hoping your suggestion is what i need, I just don't know where it goes or how to add it.

 

Thank you!

Re: Slow refresh of SharePoint list data

My data is taking forever and a day to refresh. How can I make it faster. Data is below.

 

let
Source = SharePoint.Tables("https://activestirling793.sharepoint.com/AShub/Kit", [ApiVersion = 15]),
#"ada6df12-8ddd-48d5-ada7-56a1d0236a7c" = Source{[Id="ada6df12-8ddd-48d5-ada7-56a1d0236a7c"]}[Items],
#"Expanded Category" = Table.ExpandRecordColumn(#"ada6df12-8ddd-48d5-ada7-56a1d0236a7c", "Category", {"Title"}, {"Category.Title"}),
#"Expanded Product" = Table.ExpandRecordColumn(#"Expanded Category", "Product", {"Title"}, {"Product.Title"}),
#"Renamed Columns" = Table.RenameColumns(#"Expanded Product",{{"Category.Title", "Product"}, {"Product.Title", "Size"}}),
#"Expanded lookup" = Table.ExpandRecordColumn(#"Renamed Columns", "lookup", {"Full Name", "Job Title", "Line Manager", "Status", "Team", "Location", "Request Date", "Approved", "ID"}, {"lookup.Full Name", "lookup.Job Title", "lookup.Line Manager", "lookup.Status", "lookup.Team", "lookup.Location", "lookup.Request Date", "lookup.Approved", "lookup.ID"}),
#"Removed Columns" = Table.RemoveColumns(#"Expanded lookup",{"FileSystemObjectType", "Id", "ServerRedirectedEmbedUri", "ServerRedirectedEmbedUrl", "ContentTypeId", "ComplianceAssetId"}),
#"Changed Type" = Table.TransformColumnTypes(#"Removed Columns",{{"Quantity", Int64.Type}}),
#"Renamed Columns1" = Table.RenameColumns(#"Changed Type",{{"lookup.Full Name", "Full Name"}, {"lookup.Job Title", "Job Title"}, {"lookup.Line Manager", "Line Manager"}, {"lookup.Status", "Status"}, {"lookup.Team", "Team"}, {"lookup.Location", "Location"}, {"lookup.Request Date", "Request Date"}, {"lookup.Approved", "Approved"}}),
#"Changed Type1" = Table.TransformColumnTypes(#"Renamed Columns1",{{"Request Date", type date}})
in
#"Changed Type1"
