Hi SAGEX,

If you are referring to Declared packing "FUNPKD", the answer is not possible. However, in the Pick tickets "GESPRH", using Stock issues will allow changing the serial number. 

Hi VanessaQ It always appears empty in this section.

But when I go Stock issue entry, it displays the values.

Hi, 

Please check the setup of the Packing transaction. If you still need assistance, I suggest opening a support ticket with your local Sage customer support.
