Difference between the current and previous value of a measure in webi
I have a Budget report with Month and Budget value, in this report the budget data changes more than a couple of time in a month (in back-end).
In the report there will be the latest Budget value of the month, because it is a daily scheduled report.
My requirement is to show the difference between the current value and previous value of the month.
I am able to show alerting of the data changes by using the feature "DATA TRACKING" but will not get the difference of the current and previous.
Please let me know if any possibility.
