DAX measure not working when RLS is turned on - Join paths are expected to form a tree

问题

In Power BI, I have the following error for a measure when RLS is turned on (this error does not show when RLS is off):

Join paths are expected to form a tree but the table has two join paths

These are the relevant relationships in the model:

I have an inactive relationship. This inactive relationship is used in the measure with the problem. But as it is inactive, I would have thought it wouldnt be an issue?? The measure is:

TTipsInvs =
VAR SalesValue =
    CALCULATE (
        SUM ( ANSAPBICustomerTransDetailed[Outstanding] ),
        USERELATIONSHIP ( 'ANSAPBICustomerTransDetailed'[SiteID], ANSAPBISites[Site ID] )
    )
RETURN
    IF ( ISBLANK ( SalesValue ), 0, ( SalesValue ) )

Any way to avoid this issue when RLS is turned on?

Cheers for all help

TTipsInvs =
VAR SiteID =
    CALCULATETABLE (
        VALUES ( ANSAPBISites[Site ID] ) )
VAR SalesValue =
    CALCULATE (
        SUM ( ANSAPBICustomerTransDetailed[Outstanding] ),
        TREATAS ( SiteID, 'ANSAPBICustomerTransDetailed'[SiteID] ) )
RETURN
    IF ( ISBLANK ( SalesValue ), 0, ( SalesValue ) )

Did a quick test: And this looks to work without the need of enabling or disabling relationships.

Before RLS:

After RLS:
