Step 1 - Scenario
You are creating an Exact Data Match (EDM) classifier in Microsoft Purview.
EDM requires preparing a sensitive information source table (such as employee IDs, customer account numbers).
This table must be hashed and uploaded into Microsoft Purview.
Only authorized users can perform this sensitive upload operation.
Step 2 - Required permissions for EDM upload
Microsoft's documented process states:
To hash and upload EDM source data, you must assign users to the EDM Data Uploaders security group.
This group is a security group created in Microsoft Entra ID (formerly Azure AD).
Membership in this security group grants permission to perform the upload.
# Reference: Configure Exact Data Match (EDM) in Microsoft Purview
"To upload the hashed data file to Microsoft Purview, you must add users to a security group named EDM_DataUploaders. This group is required to give permissions for EDM uploads." Step 3 - Why not the other options?
A). Microsoft Entra enterprise application # Used for app integration, not EDM uploads.
B). Purview role group # Provides compliance portal permissions but not EDM upload rights.
D). Microsoft Entra app registration # Used for API access, not relevant here.
E). Microsoft 365 group # Collaboration group, not for secure upload rights.
