I have the below code in RLS that is making my report extremely slow:
What am I doing wrong?
Role1:
Employee table:
=[NT Username] = USERNAME()
Projects table:
=[Key_Project] IN
SELECTCOLUMNS(
FILTER(
'Engagement Role'
,'Engagement Role'[UserName] = USERNAME()
)
,"Key_project"
,'Engagement Role'[Key_project])
Role2:
Employee table:
=[TeamLeadEmployeeID] IN
SELECTCOLUMNS(
FILTER(
'Employee Current'
,'Employee Current'[NT UserName] = USERNAME()
)
,"RLS_Ids"
,[Employee Number])
Projects table:
= VAR MyEmployeeNumber=
SELECTCOLUMNS(
FILTER(
'Employee Current'
,'Employee Current'[NT Username]=USERNAME()
)
,"EmployeeNumber"
,'Employee Current'[Employee Number]
)
VAR My_Employees =
SELECTCOLUMNS(
FILTER(
'Employee Current'
,'Employee Current'[TeamLeadEmployeeID] = MyEmployeeNumber
) ,"EmployeeNumber"
,'Employee Current'[Employee Number]
)
RETURN
[Key_project] IN
SELECTCOLUMNS(
FILTER(
'Engagement Role'
,'Engagement Role'[Employee Number] IN My_Employees
)
,"Key_project"
,'Engagement Role'[Key_project]
)
