## Use dimension as variable parameter

Hi all,

This is driving me nuts. I have a field full of integers (from 1 to 12, called "Loop", I also tried to generate this via ValueLoop with no luck), and a variable that gets an integer as parameter.

When I enter (in a straight table) the field as dimension and the variable with the dimension name as parameter, it returns 0 for all rows. When I enter the variable with a set parameter, it works.

My final goal is to do an aggr sum over "Loop" field, that sums the variable evaluated in each of the "Loop" members and multiply it for a weighting formula that depends on the "Loop" values.

Attached you can find an image of what I'm doing.

Thank you all...

Hi Lisa, thanks for your time. the definition is:

vFcst_(\$1) = Sum({\$<TipoDoc = {'BQ', 'BR', 'B8'}, AñoMes = {\$(=\$(vAñoMes(\$1)))}, Año=, Mes=>} Piezas)

It is the forecast (tipodoc means these are for forecast), in the selected year/month (vAñoMes(\$1)) in units (piezas), ignoring year (año) and month (mes) when selected.

vAñoMes(\$1) =

If(\$1 = 0,
Max(AñoMes),
If(\$1 < 0,
If(Max(Mes) <= -\$1,
(Max(Año) - 1) * 100 + Max(Mes) + (12 + \$1),
Max(AñoMes) + \$1),
If(Max(Mes) > (12 - \$1),
(Max(Año) + 1) * 100 + Max(Mes) - (12 - \$1),
Max(AñoMes) + \$1)))

It is the year * 100 + month, so when I do a set analysis on a selected month it works with only one condition, for the current, previous 12 or next 12 year/months.
