UserPrincipalName

Comments

• The function returns a text string of the user's principal name or UPN. UPN's are usually in the form username@domain.com - which is often identical to the email address.
•  UPN's are generally available when:
  • they are manually supplied in the admin
  • An Active Directory has been used as the authentication provider
  • SAML authentication has been used as the authentication provider.
• The function takes no inputs
• The function is often used to customize the way queries or formula's operate based on the user that is currently running a report or dashboard. It can also be used in driving member level security for data models - allowing a data model to be customized for each user logging into the application.

Different Function types

• This function is like the MDX username function.
• The other "identity" functions can be used to secure and customize the analytics experience. For more see the UserName function.

Examples

This example shows how to use the UserPrincipalName function to create a member object from a table called "security", on a column called "UPN".

StrToMember([Security].[UPN],UserPrincipalName())

If the logged in user was called "john.smith@abc.com", it would return a member with unique name [Security].[UPM].[John.Smith@abc.com]. If this was used in the member security settings for a model in the admin settings, it could be used to filter all the rows in the Security table of model, which in turn would secure the data for the entire model .

So if the security table showed that john.smith@abc.com matched up with USA, then this function would limit the entire data model to only show USA data.

An alternative to the above approach, would be to set security on the country table directly, using a non-empty function and the following use of the username method.

NonEmpty( AllMembers([customers].[Country]) , (StrToMember([Security].[UPN],UserPrincipalName())) )
