Network wise PR creation in CJ20N (PS)

Question

Hi all,
I have one requirement regarding PR creation through CJ20N. In PS scenario, under one project there will be number of WBS elements and under each WBS element number of network will be there and under each Network there will be number of activities. We will add materials under these activities. There are two type of PR creations by releasing networks in CJ20N, they are
1) Network wise PR creation - through the network PR number will be same and line items will be different.
Example : P->W->N->A1-> M1   ---> PR1/1
                                        M2  ---> PR1/2
                                A2-> M3  ---> PR1/3
                                        M4  ---> PR1/4
2) Material wise PR creation - for every material, PR number will be different.
Example : P->W->N->A1-> M1  ---> PR1/1
                                         M2  ---> PR2/1
                                A2 -> M3  ---> PR3/1
                                         M4  ---> PR4/1
Through customization, we can create Network-wise PRs or Material-wise PRs. But my requirement is to create Activity-wise PRs, in which PR number will be same with in an activity and it will differ with another activity under same network.
Example : P->W->N->A1-> M1   ---> PR1/1
                                        M2  ---> PR1/2
                                A2-> M3  ---> PR2/1
                                        M4  ---> PR2/2
For this, there is no option in customization. Please let me know is this possible through enhancements/BADIs? or is there any other way to do?
Thanks in Advance,
Siva Sankar.

Dear All,
We had a similar requirement in one of our client, the details are as follows:
Client’s requirement was to generate plant wise number range for Purchase Requisition created in Project System though T-Code CJ20N. Standard SAP don’t have any facility for plant wise document type or plant wise number range for Purchase Requisition created in Project System.
Plant wise document types and its number ranges are already defined in system but as per standard settings of PS system - PRs created from project system are considering only for one document type i.e. maintained in the configuration. There is no facility to select document type as per plant in CJ20N in standard SAP.
We have implemented two user exists EXIT_SAPLCOZF_001 & EXIT_SAPLCOZF_002 for attaining the specified functionality.
Please let me know if this is useful to you, I will update the complete solution in the thread.
