iExpense Invoice Not Getting Generated

Hi,

We are implementing iExpense module. We have done all the requisite setups for iExpense. We are able to enter Expense report, allocate expense, forward it to approver and approver could approve it. However, we have not created employee as supplier before submitting the report. The scenario is:

Any person can be joining the company and may enter expense report. It is not necessary that the employee is created as supplier.

For this, we have enable Automatically create employee as supplier option under payables option. However, after getting expense report approved and Expense Report Export program is run, the invoices are fetched by the program but the invoices are not generated.
