SRM attachments transfer

Dear ALL,

We are on SRM 7.02 and Ecc6.0 Ehp4.
Please let us know the standard SAP behaviour on attachment transfer for the below scenarion:

• Is is possible to transfer attachments at PR item level to SC item level in plan driven procurement scenarios
• Is it possible to transfer attachements from SC to PR/PO in case of classic scenario.
• Can attachments be transferred from confimation and invoice from SRM to MM.

Please confirm if the below scenarios are possible without DMS system in place.

Thanks and Best Regards,

Jay
