Dataset Column and Measure Name

Hi All,

I have a dataset name called A1, and by using that dataset I created a report.

My Requirement is when I change the column name in a Data set A1 it does not reflect on my report which contains the same column.

I manually changed the column name in my report.

Is there any way to do this one without doing manually?. Please help me to identify this one.

Thanks in Advance.
