Integration of pegging relationship between AATP and IBP OBP

Hello Experts

I have a requirement where we have both IBP OBP and AATP in S4HANA in scope. what I want to acheive is the following.

1) Execute constraint forecast optimizer in OBP to generate supply plan

2) Then execute the confirmation run in IBP so that it generate the pegging relationship between each demand and supply element..

3) Now before I want to execute the deployment in OBP I want to send the reswult of the confirmation run in S4 so that AATP can repeg those exisiting pegging that cane fropm OBP and generates in own fixed or dynamic pegging in S4 AATP.

4) Then I want the AATP pegged orders to be transferred back from S4 HAN to IBP OBP where I want to run the deployment based on the revised peggng that came in from AATP

Now my question is as below

a) After the confirmation run can I transfer the orders from IBP to S4 along with the pegging that has been created as a part of the confirmatrion run ? Is that possible using the exisitng SDI outbound ?

b) Once AATP run generates the fixed / dynamic pegging in S4 can i transfer those order along with the AATP pegged relationship uysing standard SDI inbound ? Or is their a way to bring the orders back to IBP along with the AATp pegging ?

c) In case the above is possible somehow will the deployment run in IBP respecyt the pegging generated in AATP ?

Any thoughts, suggestions or prior exprience on this ? Please feel free to share.
