Purview : comment filtrer les résultats “Data products” par termes du glossaire ?

Miriane — Thu, 23 Apr 2026 13:39:12 GMT

a { text-decoration: none; color: #464feb; } tr th, tr td { border: 1px solid #e6e6e6; } tr th { background-color: #f5f5f5; }

Bonjour,

Je teste Microsoft Purview (Unified Catalog) avec des produits de données auxquels j’ai associé des termes de glossaire.

Les termes de glossaire sont publiés et visibles dans l’onglet Découverte → Glossaire d’entreprise.
Les produits de données sont également publiés et retrouvables via la recherche.

Cependant, je ne vois pas d’option (ou elle ne retourne aucun résultat) pour filtrer les résultats de recherche des produits de données par termes de glossaire, contrairement à d’autres filtres disponibles (ex. Propriétaire, Type de produit)

Est-ce que le filtrage des produits de données par termes de glossaire est supporté dans l’onglet Découverte ?
Si oui, y a-t-il des pré-requis ou conditions particulières (ex. type de glossaire, indexation/délai, association au niveau data product vs assets, etc.) ?

Governing Entra‑Registered AI Apps with Microsoft Purview

Prashbv — Thu, 02 Apr 2026 13:52:52 GMT

As the enterprise adoption of AI agents and intelligent applications continues to accelerate, organizations are rapidly moving beyond simple productivity tools toward autonomous, Entra‑registered AI workloads that can access, reason over, and act on enterprise data. While these capabilities unlock significant business value, they also introduce new governance, security, and compliance risks—particularly around data oversharing, identity trust boundaries, and auditability.
In this context, it becomes imperative to govern AI interactions at the data layer, not just the identity layer.

This is where Microsoft Purview, working alongside Microsoft Entra ID, provides a critical foundation for securing AI adoption—ensuring that AI agents can operate safely, compliantly, and transparently without undermining existing data protection controls.

Lets look at the role of each solution Entra ID vs Microsoft Purview

A very common misconception is that Purview “manages AI apps.” In reality, Purview and Entra serve distinct but complementary roles:

Microsoft Entra ID

Registers the AI app
Controls authentication and authorization
Enforces Conditional Access and identity governance

Microsoft Purview

Governs data interactions once access is granted
Applies classification, sensitivity labels, DLP, auditing, and compliance controls
Monitors and mitigates oversharing risks in AI prompts and responses
Microsoft formally documents this split in its guidance for Entra‑registered AI apps, where Purview operates as the data governance and compliance layer on top of Entra‑secured identities.

Lets look at how purview governs the Entra registered AI apps.

Below is the high level reference architecture which can be extended to low level details

1. Visibility and inventory of AI usage

Once an AI app is registered in Entra ID and integrated with Microsoft Purview APIs or SDK, Purview can surface AI interaction telemetry through Data Security Posture Management (DSPM).

DSPM for AI provides:

Visibility into which AI apps are being used
Which users are invoking them
What data locations and labels are touched during interactions
Early indicators of oversharing risk

This observability layer becomes increasingly important as organizations adopt Copilot extensions, custom agents and third‑party AI apps.

2. Classification and sensitivity awareness

Purview does not rely on the AI app to “understand” sensitivity. Instead the Data remains classified and labeled at rest.
AI interactions inherit that metadata at runtime
Prompts and responses are evaluated against existing sensitivity labels

If an AI app accesses content labeled Confidential or Highly Confidential, that classification travels with the interaction and becomes enforceable through policy. This ensures AI does not silently bypass years of data classification work already in place.

3. DLP for AI prompts and responses

One of the most powerful but yet misunderstood purview capabilities is the AI‑aware DLP.

Using DSPM for AI and standard Purview DLP:

Prompts sent to AI apps are inspected
Responses generated by AI can be validated
Sensitive data types (PII, PCI, credentials, etc.) can be blocked, warned, or audited
Policies are enforced consistently across M365 and AI workloads

Microsoft specifically highlights this capability to prevent sensitive data from leaving trust boundaries via AI interactions.

4. Auditing and investigation

Every AI interaction governed by Purview can be recorded in the Unified Audit Log, enabling:

Forensic investigation
Compliance validation
Insider risk analysis
eDiscovery for legal or regulatory needs

This becomes critical when AI output influences business decisions and regulatory scrutiny increases. Audit records treat AI interactions as first‑class compliance events, not opaque system actions

5. Oversharing risk management

Rather than waiting for a breach, Purview proactively highlights oversharing patterns using DSPM:

AI repeatedly accessing broadly shared SharePoint sites
High volumes of sensitive data referenced in prompts
Excessive AI access to business‑critical repositories

These insights feed remediation workflows, enabling administrators to tighten permissions, re‑scope access, or restrict AI visibility into specific datasets.

In a nutshell, With agentic AI accelerating rapidly, Microsoft has made it clear that organizations must move governance closer to data, not embed it into individual AI apps. Purview provides a scalable way to enforce governance without rewriting every AI workload, while Entra continues to enforce who is allowed to act in the first place. This journey makes every organizations adopt Zero Trust at scale as its no longer limited to users, devices, and applications; It must now extend to AI apps and autonomous agents that act on behalf of the business.

Importación de términos en un glosario (tipo clásico) con metadatos de tipo entero

anmarmon — Tue, 17 Mar 2026 16:35:27 GMT

Buenas tardes.

Estamos haciendo una importación de términos mediante archivo CSV en un glosario (tipo clásico).

Dicho CSV usa Plantillas personalizadas con metadatos que tenemos definidos como enteros, metadatos como Precisión y Longitud. El problema nos viene cuando importamos dichos metadatos (como son opcionales ) y en el fichero viajan en blanco... Purview nos asigna a dichos metadatos el valor de cero. Es decir que en ausencia de valor, le pone un cero. Lo cual no es lo que buscamos. Tampoco podemos modificar el metadato del término una vez importado ya que a pesar de que lo dejamos en blanco al guardar el término le vuelve a asignar el valor de cero. Alguien mas ha tenido esa problemática?

He leido que la forma de solucionarlo es definiendo aquellos metadatos que son opcionales de tipo String, que es un tipo de dato que acepta valores nulos.

Unified Catalog Self-Serve Analytics - Data products and other elements do not sync

hentone — Tue, 17 Feb 2026 10:27:52 GMT

Dears,

I intend to create a custom interface through a PowerBI report in Fabric to distribute Purview Unified Catalog browser.

I use the feature "Unified Catalog Self-Serve Analytics" to deliver the Unified Data Catalog content in a Fabric Lakehouse. However, from the 44 data products created, only 22 are delivered to the lakehouse, in the data product table I have tried in different lakehouse, same result.

I would love some advice to help me configure this properly. Do you face the same issue ?

Best,

Antoine

Salesforce to MS Purview Integration

fmcmahon — Fri, 06 Feb 2026 14:49:58 GMT

Hi, we are trying to setup Salesforce to MS Purview Integration for Data Mapping.

Registration step is straightforward; however, we have run into issues trying to setup the scan itself.

Error: Failed to testConnection: Exception when processing request: Connector Exception: Server returns ResponseCode:'400'

We have raised this as an issue for MS Support but not making much progress.

Any tips, advice or links to how to guides etc. would be very much appreciated!!

Shutdown impossible, How to cancel a Norton subscription fan running Update KB5073455

poiuytre — Tue, 03 Feb 2026 06:53:48 GMT

Hi!

I'm running Windows 11 Enterprise, OS Version Dial 87.7.41934 . 68. BIOS version: LENOVO R2SET29W (1.05 ). System model 21S7S0ER00. Intel processor Family 6 Model 181.

After the latest update KB5073455 I'm experiencing inability to shutdown the computer. Also, a very annoying problem since the latest update is that the computer fan is constantly on since startup. Closing the lid of the laptop will not turn the fan off and will continue until the battery runs out. Because of the corporate environment, I am unable to advancedly control the fans, or for example uninstall the latest update until a fixed one is provided. Do you know when can we expect a fix to be released? Thank you already in advance!

Best regards, dhiraj

How to cancel a Norton subscription Allow Uniqueness of Glossary Terms across Governance Domains

poiuytre — Tue, 03 Feb 2026 06:48:32 GMT

When glossary terms are created and published, there is no check for the same term name in another governance domain. Some organizations do want to enforce term uniqueness across all domains. Would it be feasible to provide an optional switch in Unified Catalog settings to turn this on?

Cross workspace lineage for Fabric Lakehouse tables in Purview

sarav_s — Thu, 29 Jan 2026 11:39:37 GMT

I’m currently exploring lineage capture in Microsoft Purview for Fabric Lakehouse tables that are spread across multiple workspaces, following medallion architecture (Bronze, Silver, Gold in separate Fabric workspaces).

While reviewing the documentation, I noticed the stated limitation around cross-workspace lineage for non-power BI assets, as mentioned here:

snippet from

https://learn.microsoft.com/en-us/purview/data-map-lineage-fabric

Is there any update or workaround planned to support cross-workspace Fabric lineage in Purview?
Is this limitation on the product roadmap or actively being worked on?
Until native support is available, are there any recommended design patterns to handle lineage in this scenario?

How to Unassign Assets from Data Products in Microsoft Purview at Once

pardis1368 — Thu, 13 Nov 2025 05:16:46 GMT

Hello,

I’ve assigned around 100 assets to a specific data product and would now like to unassign all of them at once, rather than removing them individually.

Using the Purview REST API with Python, I was able to retrieve the list of my data products and successfully identify the target data product. However, I haven’t been able to fetch the list of assets currently assigned to it, which prevents me from performing a bulk unassignment.

Could anyone please advise how to retrieve and unassign all assets from a data product programmatically?

Purview workspace scan: table visible but metadata not ingested

faizfablillah — Fri, 31 Oct 2025 03:26:06 GMT

I'm copying gold tables from a dev workspace lakehouse to a user workspace warehouse in Fabric. The copied tables appear correctly in the warehouse, but when I run a Purview scan on the entire user workspace, all metadata is ingested except for one specific table.

All other warehouse objects scan successfully - only this particular copied table is missing from Purview. What could cause this selective scanning issue?

Custom Attributes with 1 to Many relationship

vlearn — Wed, 17 Sep 2025 12:22:20 GMT

Hi All,

I am looking to enhance an asset (report) by adding custom metadata fields, such as subscription details. However, each report can have multiple subscriptions, creating a one-to-many relationship. Since managed attributes do not support this, what is the recommended approach to address this in Purview?

Data product search is broken: no results for partial terms

Rik — Wed, 10 Sep 2025 08:24:54 GMT

Searching for data products using partial terms returns zero results, despite the existence of data products with matching names. For example, searching for 'risk' yields no results even though we have three data products that have 'riskscores' in their names.

I have created a support ticket, and was told that the PG has stated this behavior was by design. I just can't wrap my head around this statement. Search is the reason why data catalog tools are popular and help democratize data, and this type of searching doesn’t really help to make the data products discoverable.

A feature request was created (3135) but I was also asked to post here for visibility.

Here's some proof:

Cannot see Data Map and Unified Catalog in the free version of Microsoft Purview

JackDong — Mon, 25 Aug 2025 22:46:17 GMT

Hey, I am trying to setup a data connection in the free version of Microsoft Purview. However, I cannot see the Data Map and Unified Catalog features. Is this the intended limitation of the free version? Or do I miss something?

Feature request: Get rid of "Welcome to new Microsoft Purview portal" screen

Rik — Thu, 07 Aug 2025 08:58:59 GMT

Any new user of Purview DGS will be shown this screen:

I strongly believe this should be an admin led tenant-wide decision, and not an 'any new user on it's own decision'.

The screen is confusing and completely unnecessary for new users with "Global Catalog Reader" permissions only. The problem with this screen is that it results in some users landing in the classic portal, while all documentation and training materials that we share are based on the new portal.

My suggestions would be to move this option to 'settings'. After all, as Microsoft, you want your users to use the new portal too, right?

P.S. in the meantime, please get rid of the homepage and move all that under a 'getting started' page: Catalog homepage improvements are urgently needed | Microsoft Community Hub

Building a ChatGPT like app on top of Purview catalog data

GraemeW — Mon, 14 Jul 2025 10:17:26 GMT

We've started experimenting with the Purview catalog and added some governance domains and data products. This helps us build up a rich source of meta data especially when linked with the glossaries and data assets.

However, what we really want to get to is a solution where users can ask a question based on their objective and get told which report to run / website to access etc, like you would do with ChatGPT. The Purview CoPilot seems to be focussed on security as far as I can tell. I've got an idea that this can be achieved by using the Atlas APIs (confirmed by ChatGPT) but was wondering if this is something anyone else has done, if there is a sample app out there anywhere, or just if there's a better way of achieving our objective?

Challenges adding large numbers of assets to a Data Product in Unified Catalog

taddaRxC — Mon, 09 Jun 2025 15:55:56 GMT

The client's needs oblige us to add the tables from a SQL database into the data product; they've also got a use case for a massive file share.

We are hitting a wall in finding a programmatic solution to bring these data map assets into the Product, and the portal fails when trying to add more than 100 objects at a time.

Looking for a timeline for the release of APIs and tools to address this?

Purview Data Governance: Grant access to business consumers search Unified Catalog "Data products"

Sergio_Londono — Tue, 03 Jun 2025 22:28:29 GMT

Hello Team,

I am in Microsoft purview as regular users (business Consumer) to search in Unified Catalog for organization data associated to customers.

The administrator told me they granted me the following roles:

Data Map collection: Data Reader

Governance Domain: Local Catalog Reader.

Governance domain Published

Data product published:

I am able to connect to Purview unified catalog > Discovery > Data Asset and see all the data asset in the data map collections.

however, When I try to access Purview Unified Catalog > Discovery > Data Product > search keyword "Customers" which is a published data products, I got error 403.

Please see the images for the context.

the Microsoft documentation is very confusing about how business consumer can access the data products.

How can I grant access to regular users to search corporate data in Purview Unified catalog for data products?
