@Karan The Package Subtab in the Item fulfillment when using native Fedex integration is actually a sublist with ID:

packageFedex

you can find that in the Record Browser in the Item Fulfillment record... However, if you are using something else, for example PaceJet that Sublist is kind of replaced with something custom by PaceJet.

Hi @alien4u, yes, I check the Record Browser for the packages subtab, but I couldn't find the fields I mentioned in the packageFedex list.

you need to check those fields IDs maybe those are custom fields... or maybe you have a custom integration with a Package Sublist and you think you have the native Fedex one.

Thanks...I will check it out.
