How can I create an expense report myself in Expense Assistant?

You can't create an expense report in Expense Assistant. Expenses created in the Assistant are automatically rolled up into an expense report and submitted to your manager. This process occurs few times a week.

You can't specify a named report or assign an expense to a specific report using Expense Assistant.

However, before the expense is automatically submitted to your manager, you can use the Expenses web application to create a named expense report or add the expense to an existing report. In this case, you must submit the expense report to your manager for approval. The application doesn't automatically submit such reports.
