Problem with expressions

[#1]

Hi everyone ,

I post this as i'm encountering kind of a problem with an expression In qlikview.

I ve been searching in the other posts but havn't seen an answer to my problem at the moment.

So let me show you: I have this table in Excel that i'd like to get in Qlikview to do a waterfall

Actually, i know how to do a waterfall but i need some help translating formulas for "crecen" which is " Increasing", for "decrecen" that is " decreasing"," nuevos" for "new one" and "perdidos" for " those that were lost"

In my script, i have this as fixed:

VARIABLES

vPeriodo

$(=Max(PeriodoID)

vMesAnterior

PeriodoID={"$(=Max(PeriodoID)-12)"}

In excel, i have for:

- "crecen" =IF(E2>0;E2;"") that i translated with "IF(Sum({<vPeriodo>}IMPORTE)-sum({$<$(vMesAnterior)>}IMPORTE) >>0,Sum({<vPeriodo>}IMPORTE)-sum({$<$(vMesAnterior)>}IMPORTE) )"

- "decrecen" =IF(E7<0;E7;"") that i translated with "IF(Sum({<vPeriodo>}IMPORTE)-sum({$<$(vMesAnterior)>}IMPORTE) <<0,Sum({<vPeriodo>}IMPORTE)-sum({$<$(vMesAnterior)>}IMPORTE) )"

- "perdidos" =IF(C2=0;E2;"") that i translated with "IF(Alt(Sum({<vPeriodo>}IMPORTE), 0),Sum({<vPeriodo>}IMPORTE)-sum({$<$(vMesAnterior)>}IMPORTE))"

- " nuevos" =IF(D16=0;SI(E16>0;E16;"");"") that i translated with "if(Alt(Sum({$<$(vMesAnterior)>}IMPORTE), 0),IF(Sum({<vPeriodo>}IMPORTE)-sum({$<$(vMesAnterior)>}IMPORTE) >>0,Sum({<vPeriodo>}IMPORTE)-sum({$<$(vMesAnterior)>}IMPORTE) ))"

Here is a copy of what i get in qlikview using these formulas

See that i get the same number for both Crecen/Decrecen/Perdidos/Nuevos which is, to my mind, not that easy to understand

Have i made a mystake?

Thank you for your attention,

At first glance there are several issues:

1) >> and << are bit shift operator, not comparison operator. Use > resp. < instead.

2) {<vPeriodo>} seems not to evaluate to a valid set expression.

It think you would need to use

{<$(vPeriodo)>}, with a variable definition like

PeriodoID={"$(=Max(PeriodoID))"}

Tried to change >> and << first but this has no effect

Then i added this definition of the variable you gave me but here it went kinda wrong( changed it, in the expression, too)

Here is what happened

To be honest i think that the problem comes from the way i ve been translating my formula from Excel to Qlikview as the data seems to be working well while using the first variables i gave.

The only thing that goes wrong is, to me, while calculating the expressions of "crecen,decrecen,nuevos,perdidos"

Could you upload your QVW, with some sample data (could be mock up data)?

Here is what i m working with

Thanks for your help

There was still a bit shift operator at one place and the variable name was not correctly defined.

I also added an virtual table using aggr() function to do the calculations per PARENT_ID.

This is how far I got, maybe this could be a starting point for you to apply your requirements.
