SRM/BI Question

We are implementing Extended Classic scenario in our company. We are going in with Standard Content, with that

1) while activating PO DSO (0SRPO_D1), the "invoice and Confirmation" quantity and amount fields are not populated. Do anyone have any idea why?

2) while activation confirmation DSO (0SRCF_D2) how do we handle confirmation done in ECC. Material requestion gets confirmed in ECC in our instance while services and Non-M/S item gets confirmed in SRM. Do we have to create a custom extractor for ECC confirmation?
