After SRM 5.0 upgrade BBP_DRIVER_DETERMINE not calling properly?

Question

Hello,
We have upgraded our system from SRM 4.0 to SRM 5.0.Before upgrade we are using BBP_DRIVER_DETERMINE to determine function to create PO. If is b470_po_create function then use zb470_p0_create function.
After upgrade we have tested and found that zb470_p0_create is not calling. We put a brakpoint in the implementation of BBP_DRIVER_DETERMINE it will never stop there. Before it was stopped there.
Can any one have flow how PO will create in backend system in Calssic scenario please share(with function module and BADI names).
Please tell me flow after click on order in SC  how PO will create in backend.
Please let me know ASAP..bcoz it is urgent..

Hello venkatesh,
The standard process flow as far as i know are  as below:
1. once you order teh shopping cart the workflow asscociated  get triggered  and shopping cart would go through approval process.
2. Once the shopping cart is approved  the status is set to released.
3. With the change of stauts "BBP_REQREQ_TRANSFER is triggered.
4.BBP_REQREQ_TRANSFER internally calls BBP_PD_SC_TRANSFER_INTERNAL for new structure(version of SRM)
5.Badi is called to group the PO if implemented else standard way fo SRM for grouping of PO iscarried.
6.Then SPOOL_PO_CREATE is triggered for backend PO creation.
7. Then  FM META_PO_CREATE is called.
8 Then FM META_BAPI_DISPATCH is  called.
9. Inside FM META_BAPI_DISPATCH u have the  BAPI  BBP_DRIVER_DETERMINE Called. if this  badi is implemented  it will go to implementation of badi and overwrite the FM name  with  Function module that SAP determine from table "BBP_FUNCTION_MAP".
request you to put a break point at META_BAPI_DISPATCH and check  why its not going to your BADI implementation.
10. then the function module from "BBP_FUNCTION_MAP or you badi implementaion is called and proceesed further to result in PO.
If for some reason  the "SPOOL_PO_CREATE" fails  then a spool job is created  which spools the creation of PO for later  time.
Hope this is useful to you .
Reward point if helpful.
