Hi,
I have the same measurment (oeeh.totlineamt) - configured exactly the same with the exception of Time series type.
I tried to compare the same measure for Time Series Types: Week-To-Date, Current and Year Ago.
To my suprise I am getting exactly th same values. I would expect that the sales values will be different for all these three time series.
Why this is the case? What should I add to the report to get intended values?
Extract from the report and querry below. 
Any suggestions greatly appreciated.

SELECT USING OUTER JOIN [ARSC.arsc_name] 'COL0' , [ARSC.arsc_slsrepout] 'COL1' , [ARSC.custno] 'COL2' , [WTD oeeh_invoicedt: Sum: oeeh_totlineamt] 'COL3' , [YAGO oeeh_invoicedt: Sum: oeeh_totlineamt] 'COL4' , [oeeh_invoicedt: Sum: oeeh_specdiscamt] 'COL5' , [oeeh_invoicedt: Sum: oeeh_totlineamt] 'COL6' , [oeeh_invoicedt: Sum: oeeh_wodiscamt] 'COL7' FROM [ALL] WHERE ( ( [ARSC.arsc_statustype]='true' ) AND ( [ARSC.custno]=23761 OR [ARSC.custno]=23638 OR [ARSC.custno]=19695 OR [ARSC.custno]=10721 ) )
