Expense report goes to default approver even after choosing a different cost center

Hi All,

In EBS 12.1.3 While the user is trying to submit the Expense report to new Cost Center(1000) instead of the default CC(2000) under Expense Allocation but still the Expense is getting defaulted to the default approver (Mike) from the CC(2000) for the approval.

As a workaround, the user is changing the default Approver (Mike) in Expense reports under General Information to the required Approver (Paul) for the new Cost Center (1000) whom he wants to submit the Expense report and also change the Cost-Center to (1000) under expense allocation and when doing so the expense report is going to the respective Cost-Center (1000) manager.
