When you create a calculated KBI, you must create formulas that comply with LMS's built-in calculation syntax.

Overview of formula basics:

  • The general form of a calculation is: VALUE  OPERATOR  VALUE
  • A value can be a constant number, KBI, or function.
  • A KBI, when used in a calculated formula, must be expressed as follows:

*#KBICODE\[n\]*

* The KBI name must be prefaced with the pound sign (#). * The "n" within the brackets represents the following day offsets: ** Previous days are indicated by negative numbers (-1 represents yesterday, \-7 represents the previous week, etc.) ** Today is represented by a 0 ** Future days are indicated by positive numbers (7 represents next week, etc.)

* Calculated KBIs use the following mathematical operators in the following priority: {indent:3} * Multiplication / Division % Modulo (divide and return the remainder) + Addition - Subtraction

* Functions are predefined formulas that perform calculations by using specific values, called arguments, in a particular order or structure. A function is a procedure that generates a numerical value. The formula @PAVG(4,#1024\[0\]) is a function that returns the moving average for today's value of KBI #1024 for the last 4 weeks.

Common Syntax Errors

Following are some common errors to watch out for when creating formulas:

  • Omitting the pound sign before a KBI.
    • Including only one pound sign when two are required. The system inserts a pound sign whenever it creates a KBI as the result of establishing market segments or revenue centers.
  • Omitting day offsets ([n]).
    • Omitting a bracket before or after a day offset.
  • Putting parentheses rather than brackets around a day offset.
  • Specifying non-existent or incorrect KBI codes.
