Hi Sam,
For search helps:
1) Plant: you can use the table BBP_LOCMAP in SRM
2) For Storage location you would need to use ECC table T001L as these are not replicated in SRM
For storage locations at transaction level for shopping carts, you can use SRM table BBP_PDBEI with the shopping cart item GUID from CRMD_ORDERADM_I
Hope this completes complete logic for you to design your reports.
Regards,
Ravi
