DAX measure of two layers of intersection and a validation - powerbi

Question

I need to find a measure with the following logic:
Firstly, a link is dictated by Table 2 (LinkedID column) back to Table 1 (UniqueID column) = LinkedID -> UniqueID
For example: ID 1/UniqueID AA is a S_Req and has links with ID 9/UniqueID II because ID 1 is found in Table 2 with LinkedID = II which back in Table 1 will be ID 9/Unique II and this is an E_Req, next link is to ID 3/UniqueID CC(M_Req) and from these links(S_Req linked with E_Req or M_Req) also with the help of Table2 will determine the links with an Tst, so from ID 9/UniqueID II will have link to ID 6/UniqueID FF(Tst - Passed) and ID 2/UniqueID BB (Tst - Failed) and ID 3/UniqueID II will have a links to ID 10/UniqueID JJ (Tst - Failed) and ID 8/Unique HH(Tst - Not Done)
I need a measure that calculates the total number of S_Req having at-least one TST with the TestResult "passed" and none "failed" via M_req or E_Req links = 1
= 0 (explanation: as explian above, there's an TST with "Failed" result, so the other doesn't matter) +
0 (explication: ID 5/UniqueID EE -> ID 3/UniqueID CC(M_Req) -> ID 10/UniqueID JJ (Tst - Failed) the other link doesn't matter) +
1 (ID 7/UniqueID GG(S_Req) -> ID 9/Unique II(E_Req) -> ID6/UniqueID FF (Tst - Passed) -> ID 11/Unique KK(M_Req) -> ID8/UniqueID HH (Tst - Not Done) )
Table1: ID UniqueID TestResult S_Req M_Req E_Req Tst
Table1 :

That means will be a two layer intersection as i explain earlier: For now all i got is a total number of S_Req that have at least a link with M_Req or E_Req and that's only one layer of intersection:
Measure = VAR _tab1 = CALCULATETABLE ( VALUES ( 'Table 1'[ID] ), FILTER ( 'Table 1', 'Table 1'[S_Req] = 1 ) ) VAR _tabuid = CALCULATETABLE ( VALUES ( 'Table 1'[UniqueID] ), FILTER ( 'Table 1', 'Table 1'[S_Req] = 1 || 'Table 1'[E_Req] = 1 ) ) VAR _tab2 = CALCULATETABLE ( VALUES ( 'Table 2'[ID] ), FILTER ( 'Table 2', 'Table 2'[LinkedID] IN _tabuid ) ) VAR _tab3 = INTERSECT ( _tab2, _tab1 ) RETURN COUNTX ( _tab3, [ID] )
