RSS P43E10 - how does the GL account set up in the commodity structure set up used when entering a R

Hi,

So part of the Commodity Set up is the "G/L Account" tab where you could add GL Accounts as part of the set up. My expectation on how this would be used is that it would be available in the P43E10 screen when entering a requisition - same as how you could click on supplier and Item number.

Comodity Structure Set up

However, when I go to P43E10 to enter a requisition, the account number is still blank and  the Account section is not seen in the application either:

Where does that Commodity Account set up get used in the RSS? Am i missing something?
