How to calculate previous Date 's sum(Sales)?

[ananyaghosh]

Hi,

I am using the below table:

[Data]:
load * inline [
DateData, Sales
12/11/2017, 2012
12/10/2017, 2015
12/09/2017, 2016
12/08/2017, 2017
12/07/2017, 2018
];

and use a straight table:

and use DateData as dimension and Sum({$<[Process Date] = {"$(date(only([Process Date]-1)))"}>}[Sales Posting Amount USD]) as expression. But I get '0' for all fields.

Please help me what is wrong in the expression?

Thanks,

Sandip

May be try

Above(Sum({<DateData>}Sales)) * Avg(1)

or use The As-Of Table

Here is a sample attached

Hi,

May be expression  Above(Sum (Sales))?

Hi,

I just attached my sample qvw file. Please can you edit the 'Demo' straight table chart. Currently it does not show any data for

'Prior Date Sale' column's value under it.

Thanks,

Since you used two dimension, you needed to add Total after Above

Above(TOTAL Sum({<[Process Date]>}[Sales Posting Amount USD])) * Avg(1)

Hi,

it looks ok. But I need to implement the logic as : if the previous day's value is null or not exists in data model, then it will be null, but you can see that for Prior Date: 12/07/2016 , it is not present in the data model, but the prior date sale value is coming for 12/08/2017. SO it should be null or blank value. So instead of showing -100 it should show only 0 in the table.

So the logic should be if a date's prior date is not present in the data, it will show null or 0 prior date sale's column value.

Then it would be best to use The As-Of Table approach here

Hi,

I have seen it. But I did not understand how to implement it in my case.

So I am requesting you if you can implement it in my sample QVW document.

Thanks,
