Right now, a company's employee has to first re-submit a PO to the VCP, for a vendor user to be able to make changes to a PO.

In our projects business process, after initial confirmation, it is usual that a vendor makes updates to the expected (ex factory) delivery date and /or actual quantity to be shipped.

These changes should be reviewed by company employee, just like with changes for first submitted po.

nice to have: allow to set by vendor, if the vendor is allowed to submit changes to already confirmed PO's.

suggestion: tie in this change with the existing Supplier Communication Agent procedures, where an employee has to review the suggested PO changes from vendor emails.
