Qlik Sense Set Analysis Expression Previous Period Sum

[rnguyen2]

Hello,

I need some help with my set analysis expression.

I am trying to populate the beginning AR Balance for the month with the ending AR Balance for the prior month.

Below is my set expression.

Sum({$<[posting_date.autoCalendar.Date]={"$=addmonths([posting_date.autoCalendar.Date],-1)"}, BALANCE_TYPE={"DEBIT_BALANCE"}>} [AR BALANCE])

What is your expression for Ending Gross AR Balance? I am assuming that Year-Month is a dimension and here and Description is a synthetic dimension or is it a dimension also?

[rnguyen2]

The expression for Ending Gross AR Balance is 

sum({<BALANCE_TYPE={"DEBIT_BALANCE"}>} [AR BALANCE])

The Description Dimension  = [posting_date.autoCalendar.YearMonth]

[sunny_talwar]

Try this

Before(Sum({<BALANCE_TYPE = {"DEBIT_BALANCE"}>} [AR BALANCE]))

[rnguyen2]

That does not work for me.

Would you be able to share a mocked up version of your app where we can see the issue?

[rnguyen2]

I do not and I want to make sure if a prior month is deselected as a filter it does not affect the calculation.

You do not what?

I don't have a mocked version I can share.

Can you share your app? I mean it would be difficult to know what might be going on without seeing what you have
