Use the Formula Editor to write CoPlanner expressions for masks and CoPlanner Cube item properties. You can use expressions to set many properties, including filter properties, captions, tooltips and special. At run time, the CoPlanner processor evaluates expressions and substitutes the result for the value of the property.
Expressions can be simple or complex. You can type simple expressions directly in a text box on the design surface or in a dialog box. To create complex expressions, use the Formula Editor.
To open the Formula Editor, click the Expression button 
in properties.
The Formula Editor includes a code window, category tree, category items and description pane.
The Formula Editor is context-sensitive. The category items and descriptions change in response to the expression category you are working with. It supports syntax coloring to help you detect syntax errors.
Options of Formula Editor
Code window
Use the code window in the top pane to type an expression. When you open the Formula Editor, the code window contains the expression. You can replace or revise the expression. You can add function calls, operators, constants, fields, parameters and application properties.
Category
Displays categories of expressions. Choosing a category establishes a context for creating an expression and changes the list of valid values in the Item pane.
Item
Displays the list of valid values for the selected category. Double-click on an item to add the expression text for this item at the insertion point in the code window.
Description
Depending on the category and item you select, the third pane contains a description, a sample expression, or a list of valid values.
Evaluate
This is an optional button. Is opens the Evaluate Dialog box. You can insert values for all parameters and it displays the result.
Expression Constructs
Choosing a category establishes a context for creating an expression and changes the list of valid values in the Item pane.
Application Properties
The application properties are used to store reference values for calculations or processes in CoPlanner.
Client-side functions
Client-side functions are to display data in masks. They are used for dynamic column header, filter captions, tooltips, etc. You can use these functions in input masks, analysis views or row views.
Dimensions
A list of all dimensions and dimension attributes in the mask.
Imports
A list of all imports in the application.
Macros
A list of all macros in the application.
Measures
A list of all measures in the mask.
Server-side functions
The server-side parser has access to session variables, application properties and the data. Session variables and application properties have to be qualified with '@', server-side functions with 'fkt'
If a formulae contains '@' or 'fkt', the client sends the function to the server and the server executes the function.
Session variables
Session variables are properties, depending on the scenario, company and period.
