Data links Questions on Reports Builder

Question

We are currently using Reports Builder 10.1.2.3.0. We are trying to create a topology report. So, we have about 5 queries in the data models which are linked using a query links with Child Destination column in the child query.
So, here is the example:
Q1 --> Q2 (joined with Q1 child) --> Q3 (joined with Q2 child) --> Q4 (joined with Q3 child)--> Q5 (joined with Q4 child).
So, the problem we are experiencing is when Q2 has same child twice, the Q2 query is actually sending the same child id to Q3 twice (or however many times its repeating). Is there any way to distinct the child so we get only one child sent to Q3?
Here is an example:
Q1
Parent Child
A1 B1
A2 B2
A3 B3
Q2
Parent Child
B1 C1
B1 C2
B2 C1
Q3
Parent Child
C1 D1
C1 D1
C2 D3
Any help or suggestion would be greatly appreciated. Thanks.

Answer 1

You are on the right track, here is how our structure looks like:
Query1
Street, City
Query 2
City, State
Query 3
State, Country
And Queries are linked using group links.
Here is an example:
Query 1 results:
Street1 City1
Street1 City2
Query 2 results:
City1 State1
City1 State2
City2 State3
City2 State1
Query 3 results:
State1 Country1
State1 Country1
State2 Country4
State3 Country5
Note: example is not realistic, i know. just wanted to give you picture.
So, the repeating frame for Query3 gets Stateid from Query2 one by one rather than collect it and distinct it, hence the duplicates. I hope this explains it.
