Previous Value on the same table

PBI-IK — Tue, 03 Mar 2020 14:37:04 GMT

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.
