Where do I enter the object code for an expense?

In concur object code = expense type

You don't need to enter a number for the object code; instead, make sure you choose the correct expense type, for example lodging, airfare, office supplies, wireless communication service. Expenses are automatically uploaded to Vantage Financial and assigned the correct object code based on their label. If the expense type isn’t correct, the expense will have the wrong object code when it’s uploaded to Vantage Financial.
