Define and invoke function within query
That would be done like so:
let AssessmentsInfoFunction = (AreaAPI as text) as list => let Source = Json.Document(Web.Contents(“https://abc.xxx.com”, [ RelativePath= “/api/v1/gateway/platform/”&AreaAPI&”/assessmentcriteria” ] )) in Source, Source = {ClientDetails[RootAreaGuid]}, #"ListOfLists" = List.Combine(Source), #"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error), #"Renamed Columns" = Table.RenameColumns(#"Converted to Table",{{"Column1", "AreaGuidsForFunction"}}), #"Expanded AreaGuidsForFunction" = Table.ExpandListColumn(#"Renamed Columns", "AreaGuidsForFunction"), #"Added Custom1" = Table.AddColumn(#"Expanded AreaGuidsForFunction", "Custom", each AssessmentsInfoFunction([AreaGuidsForFunction])), #"Merged Queries" = Table.NestedJoin(#"Added Custom1",{"AreaGuidsForFunction"},ClientDetails,{"RootAreaGuid"},"ClientDetails",JoinKind.LeftOuter), #"Expanded ClientDetails" = Table.ExpandTableColumn(#"Merged Queries", "ClientDetails", {"ClientName"}, {"ClientName"}) in #"Expanded ClientDetails"
ImkeF might be able to assist.

#"Expanded ClientDetails"Greg_Deckler Thanks for the referral.
ImkeF Thanks so much for showing me how to define and and invoke a function within a query. This worked correctly.
I'm still however having the issue when uploading to Power BI service: [Unable to combine data] Section1/V7ClientsStaging1/AutoRemovedColumns1 references other queries or steps, so it may not directly access a data source. Please rebuild this data combination. Table: V7ClientsStaging1.
This suggestion to add the definition of the main function came from Chris Webb's blog.
At this point I'm at a complete loss on how to fix this error, I've tried privacy settings, staging tables in multiple forms, rewriting queries. Any other suggestions I could pursue would be most welcome.
Please check out this article:

Don't know if it contains sth useful for your case, though.
Have you tried integrating the content of your "Source"-step as well?
Hi There,
I'm also struggling with the same error in powerbi.com. I'm trying to reverse geolocation information based on Lat and Long through my google maps API and source of the information(lat & long) is located on a sharepoint folder.
My PowerBi pbix file has the Privacy setting adjusted.
This following error happens when I invoked a custom function with the same data source query,
"[Unable to combine data] Section1/Location/AutoRemovedColumns1 is accessing data sources that have privacy levels which cannot be used together. Please rebuild this data combination"This following error happens when I first stage the source information and then creating a secoud query to referrence the stage source with the added customer function
[Unable to combine data] Section1/Query1 (2)/AutoRemovedColumns1 references other queries or steps, so it may not directly access a data source. Please rebuild this data combinationAs you can see, stagging for not stagging the error persists in the cloud

I'm not sure how else to structure the query so that it works in powerbi.com service. Hope there is a way?Kind regards,
