## Re: how to write expression

For Prev Year.

Sum({<Supplier =p({<spend = {"0"}>}),year = {"\$(=max(year)-1)"}>}spend)

For Current Year

Sum({<spend = {"0"}>}spend)

## Re: how to write expression

Hi,

You can have 2 expression

one is if(sum(Spend)=0,sum(Spend))

2nd is sum({<Year={\$(=Year-1)}>}Spend)

But in your data there is

2017      zzz        ccc          0

2017      zzz        ccc          100

So what should be the result?

Thanks

## Re: how to write expression

when you select 2017 what will happen to XXX & YYY?

## Re: how to write expression

Hi,

Try this expression.

Sum({<Supplier =p({<spend = {"0"}>}),year = {"\$(=max(year)-1)"}>}spend)

See attached application.

## Re: how to write expression

## Re: how to write expression

the result is

supplier         part        currentyear(2017)   previousyear(2016)

zzz              ccc           0                       100

vvv              ddd           0                       20

it should consider only this

2017      zzz        ccc          0

## Re: how to write expression

then use below formula's

First 1: if(isnull(FirstSortedValue(Aggr(sum(Spend),Supplier,Part,Year),1)) or FirstSortedValue(Aggr(sum(Spend),Supplier,Part,Year),1)=0,0)

Second: if(Column(1)=0,sum({<Year={\$(=Year-1)}>}Spend))

## Re: how to write expression

Put the below expressions

Current Year:

Sum({<spend={"=0"}>}spend)

As suggested by Kaushik

Previous Year:

Sum({<Supplier =p({<spend = {"0"}>}),year = {"\$(=max(year)-1)"}>}spend)

## Re: how to write expression

Just observation, I think he is looking for current year value along with previous year value.

I tried with your solution but it is giving me sum of all values.

Ravi,

Have a look at the attached application. That will give you clear picture.
