Previous Value on the same table

Hi

i have this table :

 

I used this formula to take the previous row

 

previous = CALCULATE(
SUM('Fact Risk Decision Flow'[grd_granted_amount_value_euro]);
TOPN(1;
FILTER(
ALLSELECTED('Fact Risk Decision Flow');
'Fact Risk Decision Flow'[period] < MAX('Fact Risk Decision Flow'[period])
);
'Fact Risk Decision Flow'[period];
DESC
)
)
 
and it works correctly :
 
 
but if i want keep only the last row (Jan-20) i loose my calculation and "previous" is empty.
 
I try to change ALLSELECTED by ALL/ALLEXCEPT but nothings works.
 
I'm connect to a SSAS... so, i cannot create calculated columns.
 
Any Idea ?
 
Thanks

    // This should be the basic measure.
[Total Value] = SUM ( 'Fact Risk Decision Flow'[grd_granted_amount_value_euro] )

// PP = previous period
// Periods should have their own dedicated dimension.
// No slicing on fact tables should ever be performed.
// All columns in fact tables must be hidden. Only
// dimensions should be exposed and used for slicing.
[PP Value] =
var __onePeriodVisible = HASONEVALUE( Periods[Period] )
var __period = selectedvalue( Periods[Period] )
var __prevPeriod = __period - 1
var __result =
CALCULATE 
    [Total Value],
    Periods[Period] = __prevPeriod,
    REMOVEFILTERS( Periods )
)
return
	if( __onePeriodVisible, __result )

      Thanks for your reply but it's not exactly the solution that i need 😉

      Indeed the period could be 2 years ago and not only -1.

      I'm using SSAS 2016 so, REMOVEFILTERS and SELECTEDVALUES not works but i replace it with equivalent formula.

      Thank you by advance

        Hi PBI-IK.

        if you want to get the solution you're after, you have to do a bit more upfront work. Please define your problem more clearly and show all the involved structures.
