Expense rport re-create

Dear,

I create the expense report and I run the expense report export program then my expense reprot is showing in the Invoice workbench as an expense report type.

Problem is that I forget to setup the sequence numbering with expense report type. Now I want to now if I delete the expense reprt Invoice which is in in the Invoice workbench and re run the expense report export program then system will re create the epense report Invoice in invoice work bench?

Thanks
