Scheduled Refresh - Dynamic Data Source Microsoft Lists

[elaine1217]

I am using a query that imports all the versions of each item in a Microsoft List. When I publish the dashbaord to PowerBI it doesn't allow me to set up scheduled refreshes. Based on similar questions, I think this has to do with the Web.Contents statement, but I've updated to use relative path and it still is giving me issues. I also couldn't figure out the query parameter to past the item number and list name to the web.contents statement. Query is below. Thanks!

let
Source = (VersionsRelevantSharePointListName as text, VersionsRelevantSharePointLocation as text, VersionsRelevantItemID as number) => let
Source = Xml.Tables(Web.Contents(VersionsRelevantSharePointLocation, [RelativePath= Text.Combine({"/_api/web/Lists/getbytitle('", VersionsRelevantSharePointListName ,
"')/items(", Text.From(VersionsRelevantItemID), ")/versions"})])
),
entry = Source{0}[entry],
#"Removed Other Columns2" = Table.SelectColumns(entry,{"content"}),
#"Expanded content" = Table.ExpandTableColumn(#"Removed Other Columns2", "content", {"http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"}, {"content"}),
#"Expanded content1" = Table.ExpandTableColumn(#"Expanded content", "content", {"properties"}, {"properties"}),
#"Expanded properties" = Table.ExpandTableColumn(#"Expanded content1", "properties", {"http://schemas.microsoft.com/ado/2007/08/dataservices"}, {"properties"})
in
#"Expanded properties"
in
Source

Hi @elaine1217 ,

You need to fix the SharePoint site link and then you will be able to refresh it successfully.

let
Source = ( VersionsRelevantSharePointListName as text, VersionsRelevantItemID as number) => let
Source = Xml.Tables(Web.Contents("https://xxxxx.sharepoint.com/sites/winniz-test", [RelativePath= Text.Combine({"/_api/web/Lists/getbytitle('", VersionsRelevantSharePointListName ,
"')/items(", Text.From(VersionsRelevantItemID), ")/versions"})])
),
entry = Source{0}[entry],
#"Removed Other Columns2" = Table.SelectColumns(entry,{"content"}),
#"Expanded content" = Table.ExpandTableColumn(#"Removed Other Columns2", "content", {"http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"}, {"content"}),
#"Expanded content1" = Table.ExpandTableColumn(#"Expanded content", "content", {"properties"}, {"properties"}),
#"Expanded properties" = Table.ExpandTableColumn(#"Expanded content1", "properties", {"http://schemas.microsoft.com/ado/2007/08/dataservices"}, {"properties"})
in
#"Expanded properties"
in
Source

Hi @elaine1217 ,
you can either use a tool like Fiddler to record the queries that have been sent by these 2 approaches and compare the URLs or debug your current query like so:
Check the string in step "RelativePathURL"

let
  VersionsRelevantSharePointListName = "xxxx", 
  VersionsRelevantSharePointLocation = "yyyyy", 
  VersionsRelevantItemID = "zzz", 
  RelativePathURL = Text.Combine(
    {
      "/_api/web/Lists/getbytitle('", 
      VersionsRelevantSharePointListName, 
      "')/items(", 
      Text.From(VersionsRelevantItemID), 
      ")/versions"
    }
  ), 
  Source = Xml.Tables(
    Web.Contents(VersionsRelevantSharePointLocation, [RelativePath = RelativePathURL])
  ), 
  entry = Source{0}[entry], 
  #"Removed Other Columns2" = Table.SelectColumns(entry, {"content"}), 
  #"Expanded content" = Table.ExpandTableColumn(
    #"Removed Other Columns2", 
    "content", 
    {"http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"}, 
    {"content"}
  ), 
  #"Expanded content1" = Table.ExpandTableColumn(
    #"Expanded content", 
    "content", 
    {"properties"}, 
    {"properties"}
  ), 
  #"Expanded properties" = Table.ExpandTableColumn(
    #"Expanded content1", 
    "properties", 
    {"http://schemas.microsoft.com/ado/2007/08/dataservices"}, 
    {"properties"}
  )
in
  #"Expanded properties"

Otherwise, posting your error-message here might help as well.

Hi @ImkeF 

This is what the finished url would look like. I've tried it with my site name and list name and it works in this format:

https://sharepoint.com/sites/MySite/_api/web/Lists/getbytitle('My list name')/items(20)/versions

Hello @elaine1217 ,
not completely sure what statement your API actually expects.
Are you able to provide a sample URL that works for your use case? I could then show you how to parametrize correctly. This is really important, as the small details like quotes and brackets can make all the difference here.
