Not having field XWARE_BNK in MIRO screen

Hi Experts

I did not find the field XWARE_BNK (Indicator: Goods Items/Delivery Costs/Both) in MIRO screen when selected Ref doc category as Purchase order.

My requirement is to process delivery costs on a vendor.

Is it an authorization issue? If so please suggest the athorization object/parameter.

In case config, please suggest.

thanks
