PREVIOUSQUARTER Measure PBI Desktop

[MarkCBB]

Hi there,

I am still new to DAX. I am trying to create a measure that calculates the sales value of the Previous Quarter.

I am able to create one for the current Quarter - Works perfectly:

TQ Value = TOTALQTD([Total Value];MAIN_SALES[DATE])

Now I am trying to create one for the previous Quarter but I am not winning:

Below is what I found on MS Site - However this is not working as there is no context (The below measure returns "(Blank)") - I am using this as a value in a Card on PBI Desktop.

LQ Value = CALCULATE([Total Value];PREVIOUSQUARTER(MAIN_SALES[DATE]))

Below is the DAX Measure I created - But this does not work:

LQ Value = TOTALQTD([Total Value];PREVIOUSQUARTER(MAIN_SALES[DATE]))

I am sure I am not far off, what I am doing wrong?

Edit

This seems to be closer to what I want - However it is only taking month 1 and 2 within the previous quarter and month the 3rd Month

LQ Value = CALCULATE([Total Value];DATESQTD(DATEADD(MAIN_SALES[DATE];-1;QUARTER)))

Think I got it, seems to be working:

LQ Value = TOTALQTD([Total Value];PARALLELPERIOD(MAIN_SALES[DATE];-1;QUARTER))

Any comments or additional advice wold be most welcome.
