RLS - Direct Query (function containsrow" is not allowed)

[haputhanthree]

function containsrows is not allowed as a part of row level security on direct query models. 

I have blow data structure on backend.

1. Select PBI user and user group.

2. Each group have customers and these customers Id's should used to filter the sales table.

3. Sales table

RLS Query Used
[Customer_ID] IN
--get customers assigned to group
SELECTCOLUMNS(
FILTER(
Group_Customers
,Group_Customers[Group_ID] =
--get group ID of there PBI User
SELECTCOLUMNS(
FILTER(
Users
,Users[Emil] = USERPRINCIPALNAME()
), "Group_ID" ,Users[Group_ID]
)
) , "Customer_ID", Group_Customers[Customer_ID]
)


This works fine with the import mode but not in the direct query mode. appreciate your support on this.

Hi @haputhanthree 

This issue means that direct query doesn't support IN or Containsrow function. You may update your code in RLS, try equal.

Thank you!, but equal does not work for this scenario since it returns more than one Customer_ID.
