Duy, I appears that you have discovered how to select the Layer "Expenses", click in the Expenses Itemized area and find the Expenses Itemized choices. Now let find the User # fields.
From a Billing Item Record click on View from the Menu Bar and select "User Area" from the list. You now have expanded the Billing Item to include the User fields 1 through 8. You could create a Calculated Field in one of the User Fields that would copy the contents of theVendor Field.
Field - User 1
Back in your Layout add the User 1 field into the Expense Itemized Layer. This should work even if then close the User Area under View.
