Row level security

[Anonymous]

This is my measure for row level security. I look up the username and match the manager should be able to see the employee IDs corresponding to the manager ID. 

1 = var stock = LOOKUPVALUE(user_security_dynamic[employee_id]; user_security_dynamic[username]; USERNAME()) RETURN IF(
stock = table1[Manager ID]; 1; 0); but i get this error that a single value for column Manager ID cannot be determined. How can I change this? Thanks

Hi @Anonymous ,

You may refer to Row-level security (RLS) with Power BI.

According to your sample data. I create a role in the Manage roles as follows.

[Username] = username()

The test is this.

You can check more details from here.

Hi thanks for the link; I did try to impelemnt the links you sent; but those are not for my case.

My user security dynamic looks like this. An employee ID can have multiple usernames. 

Username	employee_id
Domain\A	1017
Domainb\A	1017
Domain\B	1019
Domain\C	2020

The rows Im trying to filter looks like this. If employee ID from above table matches with Manager_ID; then those rows should be seen.

Employee	manager_id
X	1017
X	1017
Y	1017
Z	1019
E	2020

@Anonymous That error regarding multiple values generally means you need to wrap a column reference in an aggregation function like MAX or MIN. This may help: https://community.powerbi.com/t5/Quick-Measures-Gallery/Dynamic-Hierarchical-Row-Level-Security/m-p/...

Create a calulated column with name "Flag"

FLAG=1

Now write the RLS code on Flag

Flag=IF(table1[employee_id] IN SELECTCOLUMNS(Filter('user_security_dynamic','user_security_dynamic'[UserName]=UserName()),"Id",[Emplyee_id]),1,0)
