Report to report interface doubt , RSBBS tcode ?

Question

Hi
I have gone thorugh sdn and could not get much details on this topic. There is a high level query A with the hierarchy restriciton for a single node, that is it will show the summary of that ( total hierarchy) in a row without hierarchy display and all the 3 amount fields related to it, YTD, and other period calculations.
Now I want to create a report B which will display the detailed level hierarchy of the single row in report A. so i believe we need to pass the hierarchy through hierarchy node variable in RSBBS tcode from report a to report B. Now my question is both the report's have the same column's and KF's and the same input selections. Do we need to pass the input selection of report A to report B as well or only the hierarchy variable ? Please advise if its not clear.
for example, report A
Row1         amount 1      amount 2      amount 3
Report b
Node 1          amount 1     amount 2    amount 3
     Node2                 amount 1
amount 2
amount 3
both the report have same KF's and filter's . now my questions.
1) do I need to have the same  user input selection created on report a as in report B ? Is it mandatory ?
2) if the user input some fy and fyperiod on report a, how will those be known to report B as we are passing only the hierarchy value through hierarchy node variable.
3)  how will the report B know about the user input selectioin given in report A ? Do we need to pass through in RSBBS from report a to report B ?
NOTE: report A and report B has the same filter's and same column's and same KF's. Its only the report A has an aggregated single row and report B has a hierarchy display of the info given in report A.
Thank You

Hi Meghana
Thanks for the info.
However, I need few input in this regards,  copied below from your link.
General
Characteristics that are to be
filled from the sender query should be defined as free characteristics. A
hierarchy node restriction, for example, can also be transferred to free
characteristics as a property.
Changeable variables for the
receiver query are not filled by the RRI.
I have created another query 2 with the same KF's, selection, variable's etc. When I right click and select the query 2, its showing as "No applicable data",
is it because its not able to pass the user input selection from query 1 to query 2 ?
when i use the refresh option on the top of workbook and select the same input given in query 1, it works fine.
a) May I know who can this be fixed. I believe this is the issue given below
that the changeable variables are not filled by the RRI. Is there any solution to pass the input variables from query 1 to query 2.
b) Do i need to pass the hierarchy information from query 1 to query 2 through free characteristics ? I mean shoudl i use the hierarchy variable in query 2 in free char ?
Thanks
