Supplier Stock on Hand (SOH) Data Integration from Oracle Supplier Collaboration to Supply Planning"

Hello,

I would like to know if Oracle Supplier Collaboration allows suppliers to upload their stock-on-hand (SOH) data through a portal or any other access method. Can this SOH data be retrieved and populated into a measure within the Supply Planning module?

If I create a custom measure in Supply Planning to capture supplier SOH, how would Oracle populate it? Would this be done via a collection plan, or is there a built-in integration between Supplier Collaboration and Supply Planning for this purpose?

Also, I would like to understand what Oracle Supplier Collaboration was originally designed to share data with. Is its primary function to exchange data with Supply Planning, Demand management, or other modules?
