Get a variable by its name

[#1]

Good day,

I would like to call a variable, but I would like to specify its name dynamically.

Let's say I have a dimension "test" and 3 variables : "varAAA", "varBBB", and "varCCC".

Nowaday, I use the following syntax :

if(test = 'AAA', $(varAAA),
 if(test = 'BBB', $(varBBB),
 if(test = 'CCC', $(varCCC),
 )))

If my variable were dimensions, I'ld use :

[var$(test)]

If variable could be arrays, I'ld use :

$(var[test])

If a function "getVariableByName" would exisits, I'ld use :

$(=getVariableByName('var' & test))

Is there another solution ?

you can use this logic i believe:

=$(='v'&Test)

where Test is you field with values "AAA, BBB, CCC"

and vAAA, vBBB, vCCC are your variables.

if you should vary by selection:

it might be something like this:

='$(v$(=getFieldSelections(Test)))'

(Limitation would be works for one selection only)

Hi Rocky,

This doesn't work.

Here is a sample application (see attached file).

I would like to make an array that displays :

ABOVE : 21000
BELOW : 210
EQUAL : 2100

To filter my data, I have 2*3 variables :

// Set Analysis filters
LET var_sa_ABOVE = '>$' & '(=DimDate)';
LET var_sa_BELOW = '<$' & '(=DimDate)';
LET var_sa_EQUAL = '$' & '(=DimDate)';

// If filters
LET var_if_ABOVE = 'Date > ' & 'DimDate';
LET var_if_BELOW = 'Date < ' & 'DimDate';
LET var_if_EQUAL = 'Date = ' & 'DimDate';

Nowaday, I use the following formula :

if(DimChoice = 'ABOVE',
 sum({$ <Date={'$(=var_sa_ABOVE)'}>} Value),
 if(DimChoice = 'BELOW',
 sum({$ <Date={'$(=var_sa_BELOW)'}>} Value),
 if(DimChoice = 'EQUAL',
 sum({$ <Date={'$(=var_sa_EQUAL)'}>} Value),
 )))

or

if(DimChoice = 'ABOVE',
 sum(if ( $(var_if_ABOVE), Value)),
 if(DimChoice = 'BELOW',
 sum(if ( $(var_if_BELOW), Value)),
 if(DimChoice = 'EQUAL',
 sum(if ( $(var_if_EQUAL), Value)),
 )))

I would like to use a formula in a single line, something like :

sum(if ( $(var_if_$(DimChoice)), Value))
