I select the invoice and I click on the "ADD to Asst Button" then I enter my exisiting asset number and I click on the find button then system open the add to asset screen here In this screen there is a Asset type combo but by default is showing "Capitalzied type" but I have to select the "Expense" that is system is not allowing to change the asset type in
