Fusion SCM: Responsive Self Service Procurement 25A

Summary:

As per Doc ID 2979093.1, the old self service procurement module will be retired and replaced with responsive self service procurement in 25A. Can you please advise on below:

1. If only the new procurement module will become mandatory but not the receiving module (as per our test result, receipt cannot be done in the new module for PO raised in old procurement module)
2. When importing requisition through FBDI, will PRs be imported to the new or the old procurement module?
3. There is a function to request a new supplier in the current Procurement module (Purchase requisition->More tasks->Request new supplier). Where can i find the same function in the responsive self service procurement module?
