How to cancel an I expense report which is in paid status

Hi All,

User created an i expense report giving wrong Project details. Later the Expense Report has been approved and paid. Now user realized that wrongly they entered Project information and interfaced into those Project, which is not correct.

How to rectify this issue to have an effect of that in the Project , which is User given wrongly, should not show these i expense report amounts ( removing the wrongly entered and interfaced i expense report amounts and related info ).

Regards.
