AX 2012 Sales Order Discounts Functionality (Picking Negative Quantities)

Hello,

This a general question that I accidentally posted in the Dynamics GP section. I am researching whether AX 2012  can handle credits and discounts (negative quantities) on Sales Orders lines. Is the ability to pick negative lines available in AX 2012? I'm currently working with AX 4.0, which will not allow negative item quantities (credits and discounts) to be added to pick lists.

Does anyone have any information concerning this?

Thanks,
