Need previous period transaction( dynamic period) in BI.

[ericbi]

Hello, 

I have a request from my client wants to have a dynamic previous period transaction.  for example,  if we select current period is 2018-March, then previous period is 2018-Feb.  if selected current period is Quarter 1 of 2018, then previous period needs to be Quarter 4 of 2017. 

I can create daifferent measures for different types of time period ( month, quarter, year) but I don't know to create a dynamic meausre can alternating the time unit based on the slicer selection. 

currently I have 3 slicers,  fiscal year, fiscal quarter and fiscal period(month),  not sure if it's possible to create a measure can automatically choose the proper period type .

I would create another slicer that is simply "Year", "Quarter" or "Month".  Based on that selection (SELECTEDVALUE), you can have an IF or SWITCH statement for your measure that performs the correct calculation.
