We have a Direct Query dataset in which we are trying to limit a table specifically by the domain name of the user pulling the report. This is being done in the Advanced Editor screen in the Query Editor using the Report Server solution.
The current query (when hard-coded) looks like this, and works fine:
let
Source = Sql.Database("Server", "Database",
[Query = "Select Id, DomainName From Database.dbo.Table Where DomainName = 'Hard Coded Domain'"])
in
Source
We are trying to make the 'Hard Coded Domain' piece be dynamic with the following code:
let
LoadingUser = USERNAME(),
Source = Sql.Database("SRVDB", "BI",
[Query = "Select EmployeeId, EmployeeName, DomainName From BI.Base.Employee Where DomainName = '"&LoadingUser&"'"])
in
Source
However, this produces the error: "Expression.Error: The import USERNAME matches no exports. Did you miss a module reference". Then it says "Expression.Error: The name USERNAME wasn't recognized. Make sure it's spelled correctly"
Has anyone ever seen this error before, and if so, is it even possible to use the USERNAME command to limit a query in Advanced Editor?

Hi @WSwanson,
USERNAME() is a DAX function. So you can't use it in the Query Editor that uses Power Query. Please vote on this idea. The workaround could be found here. I tested it with R code. It worked. You can try it like bellow.
let RScript = R.Execute("output <- read.table(text=system2(""whoami"", stdout=TRUE))"), output = RScript{[Name="output"]}[Value], Source = Sql.Database("SqlServerName", "contosoretaildw", [Query="select * from DimCustomer where lastname = '&output&'"]) in Source
Best Regards,
