How to enable DFF for Onhand

Hi,

Our objective is to link all supplies to it's sales order demand - for this we have created an EFF attribute at sales order level. Each time a sales order is created, it will be associated with a unique identifier. This identifier will then be passed down to planned orders in supply plan ( attribute-based planning) and then to WO, TO, PR-PO ( DFF created ) .

Question 1) : Is there a way to see this attribute in Receiving screen ?

Question 2) : How can we create DFF for Onhand. Can anyone kindly help with the setups to be done?

Thankyou
