Hi Aishwarya. So if you right click these labels, you don't have an "alias" field to click? Is this correct?
Yes Shawn, these are measures and even if i rename the measure names, i would see the "month of xxx" or "Discount of xxx" on the report.
Let me have think on this. I'll get back to you tomorrow. (Please ping me if I don't. Thanks.)
One option is to create a calculated field that uses the aggregation, table calculation, or datename/part and naming the field whatever is desired. For example, to get the month to show only Month in the header, create a calculated field similar to the following:
datename('month', [Date field])
And name the field Month.
Hope this helps a bit!
