Why am i not seeing the drop down for supply subinventory

Summary:

Hello,

All the orgs are setup and plant parameters are setup. I am trying to create a WC in Oracle manufacturing. But the supply subinventory drop down is not working. No data is coming up in the drop down. Has someone came across this before?
