Power BI is not using $filter on a OData V4 source

[Anonymous]

Hi all,

I'm using Power BI to pull data from an OData v4 source.

The problem is my OData table is very big and the query takes more than 30 minutes.

When I debugged the rest requests that are being sent from Power BI to OData I can see that it doesn't use $filter in the queries. The filter is being done on all of the data after it comes back to Power BI.

This is the query in the advanced editor:

let
    Source = OData.Feed("http://localhost:8080/odata/v4/shared_spaces/1001/workspaces/1002/", null, [Implementation="2.0"]),
    runs_table = Source{[Name="runs",Signature="table"]}[Data],
    #"Expanded release" = Table.ExpandRecordColumn(runs_table, "release", {"name"}, {"release.name"}),
    #"Filtered Rows" = Table.SelectRows(#"Expanded release", each ([release.name] = "release 373.1"))
in
    #"Filtered Rows"

Do you know how I can make Power BI use $filter?

Thanks,

Adi

Hi @Anonymous ,

Didn't the filter make sense? Don't forget to click the "Close&Apply" button.

Hi @v-xicai ,

I used the filter like you showed. 

The problem is it filter after getting all the data from the OData resource.

Power BI didn't use $filter in the OData request and becuase of that the query takes a lot of time.

Hi Adi,

I can understand your issue but to limit the data you have to apply conditions before the Odata service itself. Power BI can do filter only once after loading the complete data.
