Reclamations and returns DOCUMENT FLOW

Question

Hi,
I ve to enhance the QM01/02/03 ,DOCUMENT FLOW when ever we press document flow push button,
QM02-
provide any QN number,
in the menu
extras -> document notifications->document flow->list
rifht now it is showing only 2/3 documents in tree
but it should be modified to
The standard SAP Document Flow, but it must be modified, in order to show all the subsequent documents, and the user must be able to go directly to each subsequent documents.  
The flow must follow this hierarchy: 
For documents type ZS/ZV
- Purchase Order
    - QM Notif.
        - Stock transfer or Scrapping
             - Return Purchase Order
                   - Delivery
                       - Goods issue
                          - Goods receipt
                             - Invoice
For document Type: ZC.
- Reference document
- QM Notif.
- Return Sales Order or Credit memo req. or Debit memo req.
                                          - Return invoice or Credit memo or Debit memo
This document flows should be shown for each QN in the QM11 transaction.
menu
Notification -> Display Document flow
It is a network flow that should  as is but all the documents it should show.
it is internally calling Business objects
1. Goto transaction "QM02",
2. Provide some QN number
Observe: LIST
                 GRAPHIC
If u goto the sytem→status u ll find the program “SAPLIQS0”
Find the Function code responsible for “DOCF”
It will call a report program “RIBELF20”
For other “GRAPHIC” shown in above picture
U will find form exit “FORM fcode_docf2_f00”
Where we can create new program like above and we can insert our own Z Program.
But if u go to the program level and debug,
There is one FM "DISPLAY_DOCUMENT_FLOW_ALV" that is responsible for such type of display,
No issues,
But internally before that he extracted all the business Objects responsible for that.
How can I get all the business objects that are required to me to show the all the documents that I have already sent to u.
Below are my findings about the document flow at QM11 level.
When ever u press the Display document flow.
The O/P is
1. QM11 is the standard transaction using program “RQMELL10”.
    We can not modify the standard SAP transaction, and insert our code in this program.
     Alternative: we have to copy the program in Z namespace and attach the same to Z transaction code.
    Confirm the same whether the users are ready to use the “Z” transaction.
2. Even though they accept for this:
    The function Module responsible for the Network type of display is “QM11_LESEN_BELEGDATEN_ALLG”.
    With the input parameters as (a) QN number (b) Business Object i.e.  BUS2078 (Quality notification number) (c) maximum number of steps
    The standard function module should be used in Z namespace program; the standard function module internally calls one more Function module 
    “NERL_GET_NEIGHBOURHOOD” that is responsible for the getting business objects of the corresponding number.
     But this function module gets the only three documents data but not the else that are mentioned in the FD.
<b>Kindly provide any function module, which can meet such criteria, and the business objects of the related documents in the flow that is required.</b>
