How to refresh business view in crystal reports

I have developed a business view and used it in report. till now there is no issue.. but when I change the business element in business view, It is not getting updated in the report and every time I change I am forced to create a new report which is a very tedious task as the report is very complex.

I have tried different ways to update the business view, One of the way is "Set Datasource Location" but nothing was working for me.

I feel there would be some way to update the business view without creating new report every time.

Experts please guide me achive this task so that without creating new report all changes will get updated that are in changed business view.

Thanks for your time.
