Overview of the Builtin Functions
There are many builtin functions available to help you define your formulas. The most commonly used of these functions are as follows:
To take the average of values: AVERAGE(X1, X2,...)
To take the summation of values: SUM(X1, X2,...)
To take the minimum of values: MIN(X1, X2,...)
To take the maximum of values: MAX(X1, X2,...)
To take the product of values: PROD(X1, X2,...)
When you call a function, you must supply an actual values for all function's arguments, and separate them with a comma (','). Formula functions are not case sensitive and therefore the formula functions can be entered in both uppercase and lowercase letters.
Functions can also contain constants unless otherwise specified. For more information on constant types, see Constants.
When function parameters are derived from other functions or expressions, it is possible that parameters will not get values at all. Since regular functions cannot handle these socalled NIL values, the calculation will end to an error. In order to ignore NIL values in your formula calculations, you can enter the underscore character "_" after the function name. Therefore AVERAGE_(X1, X2,...), SUM_(X1, X2,...), MIN_(X1, X2,...), etc., are all valid functions with the exception of ignoring all supplied NIL values.
Functions that return lists of values (such as CUMULATIVE and RANGE) should not be used in formulas directly but in combination with aggregate functions such as SUM, AVERAGE, MAX, or MIN.
For example, the formula AVERAGE_(NIL,2,NIL,3), where NIL represents an undefined (null) value, will be calculated as AVERAGE(2,3).

In addition, there are different operators and wildcards available:
Consolidation Functions
Returns list of values, accumulated to the period level of the element in which the function is. 

Returns a list of cumulative values, one per each expression. 

Returns the sum of the arguments. 
ACCUMULATE
Description
Returns list of values, accumulated to the period level of the element in which the function is.
Syntax
ACCUMULATE(expression_list, accumulation_rule)
Parameters: expression_list, accumulation_rule
expression_list contains an even number of expressions separated by commas. The list has references to value series first and then either a date series or NIL reference for each value series.
accumulation_rule is one of the following values enclosed in double quotes: DEFAULT, SUM, SUM_, AVERAGE, AVERAGE_, MIN, MAX, FIRST, LAST, or LATEST.
Examples
ACCUMULATE(mea1.act(), NIL, "default") : Accumulate mea1.act() using accumulation rule of mea1 (same as "mea1.act()")
ACCUMULATE(mea1.act(), NIL, "sum_") : Accumulate mea1.act() using accumulation rule sum_ (override element's own accumulation rule with sum_)
ACCUMULATE(mea1.act(), mea1.date(), "average_") : Accumulate mea1.act() using accumulation rule average_. Accumulated values are selected (targeted to periods)
according to dates found in mea1.date().
ACCUMULATE(mea1.act(), mea2.act(), NIL, mea3.dates(), "default") : accumulate values from mea1.act() and mea2.act() with the element's own accumulation rule.
Select accumulated values for mea2.act() on the basis of the dates found in mea3.dates() series.
CUMULATIVE
Description
Returns a list of cumulative values, one per each expression. In the case there are null values in the results, they must be controlled with container functions such as SUM_ or AVERAGE_ (for example, SUM_(CUMULATIVE(?.act(), 1, SUM_)) or the CUMULATIVE_ function must be used.
Syntax
CUMULATIVE(expression_list,relative level,formula )
CUMULATIVE_(expression_list,relative level,formula )
Parameter: expression_list
A list of expressions separated by commas. An expression is a reference to element's series on a certain period.
Parameter: relative level
An integer value stating which period level will be used in the calculation. The number is a relative value, pointing upward in the period level hierarchy. Values less than 1 are considered invalid.
Parameter: formula
This parameter determines which function will be used for calculating the cumulative values. The following function names are valid: SUM, SUM_, AVERAGE, and AVERAGE_.
Examples
This function returns the average of all mea1 measure values. The calculation will start at the beginning of a period which is one level higher than the period level of sc1.mea1.
CUMULATIVE(sc1.mea1.act(),1,AVERAGE)
This function returns a cumulative sum for actual and alarm series of the current measure, scorecard and period. The calculation will start at the beginning of a period which is two levels higher than the period level of sc1.mea1.

This function calculates a cumulative sum of sales. Calculation is done with all scorecards' sales elements, closed series. Sum is cumulated one period level upwards from the saleselement's own period level. For instance, if sales is measured in day level and 'month' is next period level upwards from 'day', then cumulative sum is calculated for monthly level.

Syntax

Parameter: condition
Any logical expression. As evaluation order may affect the results, it is recommended to use parentheses with longer expressions, for example IIF(MEA1.ACT()+1=2, true, false) should be input as IIF((MEA1.ACT()+1)=2, true, false)
Parameter: true_value
The value to be returned if condition evaluates to True (i.e. <>0).
Parameter: false_value
The value to be returned if condition evaluates to False (i.e. =0).

Number lists are tested in listed order, but the testing order of measure values is not defined. Note: Using a function that ignores NULL values as the parameter for ISNULL is not supported. For example, functions like ISNULL(SUM_(NULL,1)) will return 1, even though it would seem they shouldn't.

STDEV
Description
Returns the standard deviation based on a sample. STDEV assumes that its arguments are a sample of the population.

Parameter: number_list
A list of numbers or dataseries separated by commas.
Examples
When MEA123.ACT() has the values [1,0 2,0 3,0 4,0 5,0 6,0 7,0 8,0 9,0 10,0]:

STDEVP
Description
Returns the standard deviation based on the entire population given as arguments. STDEVP assumes that its arguments are the entire population. If your data represents a sample of the population, compute the standard deviation using STDEV. For large sample sizes, STDEV and STDEVP return approximately equal values. The standard deviation is calculated using the "biased" or "n" method using the following formula:
Syntax
STDEVP(number_list)
STDEVP_(number_list)
Parameter: number_list
A list of numbers or dataseries separated by commas.
Examples
When MEA123.ACT() has the values [1,0 2,0 3,0 4,0 5,0 6,0 7,0 8,0 9,0 10,0]:
STDEVP(MEA123.ACT(AllToDate)) returns [0,0 0,5 0,8 1,1 1,4 1,7 2,0 2,3 2,6 2,9]
STDEVP(MEA123.ACT(All)) returns [2,9 2,9 2,9 2,9 2,9 2,9 2,9 2,9 2,9 2,9]

VAR
Description
Returns variance based on a sample. VAR assumes that its arguments are a sample of the population. If your data represents the entire population, then compute the variance using VARP. VAR is calculated using the following formula:
Syntax

VAR_(number_list)
Parameter: number_list
A list of numbers or dataseries separated by commas.
Examples
When MEA123.ACT() has the values [1,0 2,0 3,0 4,0 5,0 6,0 7,0 8,0 9,0 10,0]:
VAR(MEA123.ACT(AllToDate)) returns [null 0,5 1,0 1,7 2,5 3,5 4,7 6,0 7,5 9,2]
VAR(MEA123.ACT(All)) returns [9,2 9,2 9,2 9,2 9,2 9,2 9,2 9,2 9,2 9,2]

VARP
Description
Returns variance based on the entire population. VARP assumes that its arguments are the entire population. If your data represents a sample of the population, then compute the variance using VAR. VARP is calculated using the following formula:
Syntax
VARP(number_list)
VARP_(number_list)
Parameter: number_list
A list of numbers or dataseries separated by commas.
Examples
When MEA123.ACT() has the values [1,0 2,0 3,0 4,0 5,0 6,0 7,0 8,0 9,0 10,0]:
VARP(MEA123.ACT(AllToDate)) returns [0,0 0,3 0,7 1,3 2,0 2,9 4,0 5,3 6,7 8,3]
VARP(MEA123.ACT(All)) returns [8,3 8,3 8,3 8,3 8,3 8,3 8,3 8,3 8,3 8,3]
