Closing of EAM Work Orders

Hello,

In our EBS R12 (Version: 12.2.4) we have EAM module in practice.

in our procedure, we have a separate responsibility called " Job Costing User" who is doing closing of EAM work orders.

( opens the form and check what are the work orders are in complete status and one by one close the work order)

1./ what we need to do is bulk wise closing . please help me to do bulk wise closing of completed work orders.

2./ If close all the competed work orders from back end, will it be impact to financial process?

thanks
