You cannot use Power BI to visualize this list issue

If you are working with SharePoint Online list and select Integrate – Power BI – Visualize the list, but it gives you error message “You cannot use Power BI to visualize this list”, “Looks like the feature for visualizing lists is turned off. Please contact your admin to enable this feature”:

You cannot use Power BI to visualize this list

The issue appears to be not in SharePoint, but in Power BI. Note it says “You cannot use Power BI to visualize this list” and “Looks like the feature for visualizing lists is turned off. Please contact your admin to enable this feature.”

Also the url of this page is Power BI Url:
“https://app.powerbi.com/sharepointlist?spListId=%7Bd3b56”, so you’d need contact Power Platform Administrators, not SharePoint administrators.

Power BI administrator would go to Microsoft Fabric Admin portal

and ensure “Integration with SharePoint and Microsoft Lists” is Enabled for the entire organization or for specific security groups. In the last case – ensure user who is getting “You cannot use Power BI to visualize this list” is added to at least one of the groups but not added to “Except specific groups”.

If the user is allowed under “Integration with SharePoint and Microsoft Lists” so “Users in the organization can launch Power BI from SharePoint lists and Microsoft Lists. Then they can build Power BI reports on the data in those lists and publish them back to the lists.” then, normally, user would see:

and something like:

SPO Site LastContentModifiedDate vs LastItemModifiedDate vs LastItemUserModifiedDate vs Graph LastModifiedDateTime

How do we know when the SharePoint site was last updated?

We have multiple “when the site was modified last time” properties – e.g. some we can retrieve with SharePoint CSOM:

  • Site LastContentModifiedDate
  • Web LastItemModifiedDate
  • Web LastItemUserModifiedDate

Also we can get

  • MS Graph site object with LastModifiedDateTime property
  • get usage reports via Microsoft Graph (activity reports), and
  • use “Last activity” field via Admin Center GUI

On the other hand – we can view and modify site in multiple ways – visit site home page, open and/or update document/list item, change site/library settings, configure site permissions, assign site sensitivity label, setup site property and so on.

Question: which site “last modified” or “last activity” properties reflect what events/actions?

This might be important if we think of retention policies, or any kind of clean-up processes… Let say, we are getting report on abandoned sites (inactive sites), but we are also assigning sites sensitivity labels, or we are updating site custom properties (e.g. for adaptive scopes), we have an ownerless groups policy working etc.

What if we assign site sensitivity label to an old inactive (5 years old) site – would it affect retention policy since site was updated this way?

Results

So i did some tests and based on detailed results below, it seems like

  • Web LastItemModifiedDate is triggered when user just visited site (but property LastItemUserModifiedDate is not triggered)
  • If a document or list Item updated by user or app – all properties are triggered
  • MS Graph site property LastModifiedDateTime, root web property LastItemModifiedDate and Site LastContentModifiedDate – same values
  • If site custom property is updated – it does not affect any site “last modified” property
  • The same for sensitivity label updated by app – it does not affect any site “last modified” property
  • The same for Microsoft ownerless groups policy – when user accept or decline group membership – no site “last modified” properties are changed (the same is true for Microsoft 365 group last modified date/time property).

Please refer to the table below

SharePoint Sites Lookup

That’s a very common problem in SharePoint world. You are looking for a site owner but there is no tool available for regular user to find who owns the site.

Scenarios.

You get a link to some SharePoint site, but you do not have access to it. You requested access but nobody has responded. You need to find who is the site owner.

Get all SharePoint and Teams sites owners report with PowerShell

This PowerShell script pulls all tenant sites and all sites owners. The script require app authentication with Sites.FullControl.All and Directory.Read.All permissions.
PnP.PowerShell for PowerShell 7 is used.

It generates two reports

  • Owners report: one user per line, include: Site Url, Title, Owner e-mail, name and type
  • Sites report: one site per line, include: Site Url, Title, list of owners e-mails

Here is the script:


$connAdmin = Connect-PnPOnline -ReturnConnection -Tenant $tenantId  -Url $adminUrl -ClientId $clientid -Thumbprint $certThumbprint
$allTenantSites = Get-PnPTenantSite -Connection $connAdmin | Sort-Object Url
$allTenantSites.count

$sitesReport = @()
$ownersReport = @()
foreach ($tenantSite in $allTenantSites) {
    Write-Host $tenantSite.Url
    $connSite = Connect-PnPOnline -ReturnConnection -Tenant $tenantId  -Url $tenantSite.Url -ClientId $clientid -Thumbprint $certThumbprint
    $site = Get-PnPSite -Connection $connSite -Includes RootWeb, GroupId, Owner
    $siteOwnerEmail = ''
    $siteOwnersReport = @()
    if ($site.GroupId.Guid -eq '00000000-0000-0000-0000-000000000000') {
        $siteAdmins = Get-PnPSiteCollectionAdmin -Connection $connSite | ? { $_.PrincipalType -eq 'User' }
        $ownerType = 'Site Collection Administrator'
        $isGroupSite = $false
    }
    else {
        $siteAdmins = Get-PnPAzureADGroupOwner -Connection $connAdmin -Identity $site.GroupId.Guid
        $ownerType = 'Group Owner'
        $isGroupSite = $true
    }
    foreach ($siteAdmin in $siteAdmins) {
        if (!$siteAdmin.UserPrincipalName) {
            Get-PnPProperty -Connection $connAdmin -ClientObject $siteAdmin -Property UserPrincipalName | Out-Null
        }
        $aadUser = Get-PnPAzureADUser -Connection $connAdmin -Identity $siteAdmin.UserPrincipalName
        if ($aadUser.AccountEnabled) {
            $siteOwnerEmail += $aadUser.Mail + '; '
        }
        $siteOwnersReport += [PSCustomObject]@{
            SiteUrl     = $site.Url
            SiteTitle   = $site.RootWeb.Title
            IsGroupSite = $isGroupSite
            OwnerEmail  = $aadUser.Mail
            OwnerName   = $aadUser.DisplayName
            OwnerType   = $ownerType
            Enabled     = $aadUser.AccountEnabled
        }
    }
    $ownersReport += $siteOwnersReport
    $sitesReport += [PSCustomObject]@{
        SiteUrl     = $site.Url
        SiteTitle   = $site.RootWeb.Title
        IsGroupSite = $isGroupSite
        OwnerEmail  = $siteOwnerEmail
    }
}

Manage result layouts for SharePoint results in Microsoft Search

Microsoft is improving Search (MC489165):

Manage result layouts for SharePoint results in Microsoft Search

We’re making changes to Microsoft Search. This update will allow Microsoft Search administrators to change result layouts for select SharePoint content using adaptive cards with Result Type feature in Microsoft Search administration.

The default result layouts for SharePoint sites, pages, list items and Portable document format (PDF) results can now be replaced with layouts built using adaptive cards. The changes can be made for Organization level search applicable to Office.com and SharePoint home as well as site level search on SharePoint sites. Changes for Microsoft Search in Bing will be rolled out soon. Note that the feature does not support changing of Office file search results.

This message is associated with Microsoft 365 Roadmap ID 81952

Before the change, when you add a new result type under “Search and intelligence” Customizations – it looked like this:

result type content sources

So there was no built-in “SharePoint” content source as an option – only custom “external” data sources.

But with the new feature implemented list of content sources for the result type will look like this:

SharePoint and OneDrive content source

If you choose “SharePoint and OneDrive” content source – the next option would be to select type of content:

Select type of content and set rules

You also can create different result types for different types of content based on properties-based rules (e.g. one result type for all sites – and a separate result type for a specific site or hub) with optional “Set rules for this type of content”:

Default site result experience would look like

Search results with modified SharePoint result type might look like:

When you modify template via Layout Designer – it is essential to know available object properties.

You can get properties from the “Available properties” below – there is also search through properties feature.

Or you can use SharePoint Search Query Tool to get metadata on search results.

It might take hours and even days for your search to start showing new layouts, but “&cacheClear=true” should help.

DepartmentId 

If your sites are organized in hierarchy under Hub site – you can use DepartmentId managed property to include all hub-associated sites content

DepartmentId is just a hub site Id

Microsoft 365 SharePoint: prevent throttling with RateLimit headers

Bert Jansen (Microsoft) revealed some details on throttling when you access Microsoft 365 programmatically – via Microsoft Graph or CSOM and guided developers on how to regulate request traffic for optimized throughput using RateLimit headers (Here).

Demystifying SharePoint throttling

Throttling is necessary to ensure that no single user or application consumes too many resources compromising the stability of the entire system, which is used by many clients.

Throttling happens at

  • User (there are user request limits. Microsoft counts all requests linked to user
  • Application (Delegated or Application permissions)
    • Resource units per app per minute
    • Resource units per app per day
  • Farm – Spike protection

Very common reason for throttling – when an Application (Delegated or Application permissions) reaches “Resource units per app per minute” threshold.

Usually you catch HTTP errors 429 or 503, wait for some time (respect Retry-after header) and try again.

SharePoint provides various APIs. Different APIs have different costs depending on the complexity of the API, but Microsoft favor Graph API over SharePoint REST/CSOM. The cost of APIs is normalized by SharePoint and expressed by resource units. Application’s limits are also defined using resource units.

Quota depends on tenant size.

Resource unit limits for an application in a tenant (please refer to the Microsoft article)

Predefined costs for Microsoft Graph calls:

Assuming 2 resource units per request is a safe bet.

Microsoft 365 Search Vertical KQL query field limits

What is the Microsoft Search KQL query field limits for a verticals? Is there limited number of characters or lines?

You know what is Microsoft 365 Search Vertical and what is KQL query in vertical configuration, right?

Microsoft 365 Search Vertical KQL query field limits

Under Microsoft 365 admin center Search and intelligence you can configure search verticals. There are some out-of-the-box verticals – like All, Files, Sites, People and you can configure custom one.

As a part of vertical configuration – you can specify KQL query – if you want e.g. limit search with some sites or content types etc.

The question is – how many sites I can specify in this query field? E.g. can I specify 1000 sites? 10k sites?

And the answer is: It does not matter, because the limit is not in number of characters or lines.

In my dev environment I was able to save 50,000 lines (~3M characters). But attempt to save 100K lines (6M symbols) has failed (due to timeout, I believe:

Again, as I said the problem is not here.

The problem is time required for search to apply query. I.e. when you ask search to bring you something – after it gets results from index and before display results to you it applies KQL query configured for the vertical. And this time is the bottleneck.

Here is what I got measuring search response time depending on query size:

Searchresponse time,
seconds
KQL query
# of lines
KQL query size,
# of symbols
works150028,000
works5100059,000
works92000120,000
works253000180,000
works/fails303500208,000
fails353600214,000
fails3550,0003,000,000
n/an/a100,000
(can’t save KQL query
6,000,000
(can’t save KQL query)

Which means that after ~ 1000 lines (50,000 characters) KQL query size – query becomes too slow, and after ~3000 lines (180k chars) – can fail (due to timeout I’d say).

DepartmentId 

If your sites are organized in hierarchy under Hub site – you can use DepartmentId managed property to significantly decrease number of lines in query,
as you can cover all sites under the hub with

DepartmentId=<HubSiteId>
