Sugar Logic
Overview
Sugar Logic allows administrators to write simple formulas and logic checks to provide a calculation for a field or to set the visibility of a field. For more information regarding the types of fields that you can use Sugar Logic with, please refer to the Field Options documentation. A calculated field uses a formula to derive its value based on the values of other fields as well as mathematical or logical operators. A dependent field uses a formula to determine whether or not the field should be displayed. These formulas are automatically recalculated when the record is updated. In addition, when a record containing a formula's input field is updated, the formula is automatically recalculated.
Note: When creating a calculated formula for a Currency field, the currency symbol should not be used for a value (e.g., $100) in the formula. The formula should only define the numeric value (e.g., 100), as including the currency symbol will result in improperly calculated values.
When a calculated or dependent field is created or its formula is modified, all existing records in the module will not use the new formula until they have undergone a save action. To update the existing records to use the new formula, the module's list view includes a Recalculate Value action. Admin users or users with developer-level access can use this feature to cause existing records to recalculate affected fields without having to perform an update on each record individually. For more information, please refer to the User Interface documentation in the Application Guide.
Administrators can access the formula builder for the fields and options that accept formulas by selecting "Edit Formula". 
To browse all of the functions available, refer to the Complete List of Sugar Logic Functions section of this page. For more information and examples using Sugar Logic, please refer to the Sugar Logic section of the Knowledge Base, which includes articles covering the use of dependent and calculated fields. Topics range from introductory information to example Sugar Logic formulas and detailed walkthroughs of how to construct various fields and formulas in the formula builder.
Functions
Functions are listed on the lower left-hand corner of the formula builder and provide a variety of calculations, logic checks, and formatting options. To locate the function you need, simply scroll through the list or enter search criteria to narrow the list. Refer to the Complete List of Sugar Logic Functions section of this page to browse all of the available functions.
To see how to use a function, simply hover over the function to view the syntax, parameters, and a brief description of what the function does. 
The function name is followed by a comma-separated list of parameters to the function. The list specifies the data type expected for each parameter. For example, the function "daysUntil" expects one parameter of Date type.
The description in the hover text will typically specify what data type is being returned, but if it does not, the symbol to the right of the function also represents the function's data type. 
The following is a list of the possible return type symbols and the data types they return:
| Symbol | Description |
| # | Returns a Number |
| Calendar | Returns a Date object with a date and time |
| % | Returns a Boolean (true or false) value |
| A | Returns Text |
| [ ] | Returns a List |
| ? | Returns a variable data type that could be any of the above |
Fields
Fields are listed on the lower right-hand corner of the formula builder and contain the fields for the current module. Fields can be referenced in formulas and will start with a $. To locate the field you need, simply scroll through the list or enter search criteria to narrow the list. 
To add a field to the formula, simply click on the field to be added. The variable name for the field will be placed at the end of the formula. You can also type the variable names manually in the formula.
Related Field
Related fields are available to be added to formulas via the related function. You can manually add related function calls to your formula or you can build the syntax for the related function by clicking "Related Field". 
This will open a dialog box that will assist in building the syntax to use the related function. Select a module and a field within that module to pull the related field from and click "Insert". 
The resulting syntax for the selected options will be added to the formula.
Note: If a record has multiple related records to a module, the related function will pull the field from one of the related records. It is not recommended to rely on the related function to pull the same related records for a many relationship.
Rollup
In addition to adding related fields, you can also add aggregate functions on related fields to formulas via the rollup functions. You can manually add rollup function calls to your formula or you can build the syntax for the rollup function by clicking "Rollup". 
This will open a dialog box that will assist in building the syntax to use the rollup function. Select the type of rollup function (Sum, Average, Minimum, or Maximum) to perform on the module field. To perform a count of related records, please refer to the count function listed in the Functions section. Select a module and a field within that module to perform the rollup function on and click "Insert". 
The resulting syntax for the selected options will be added to the formula.
Note: Rollup functions can only aggregate number type fields.
Complete List of Sugar Logic Functions
Some functions require a given number of parameters while others are more flexible. Most parameters require a specific data type to be passed in for the function to work. Functions with the same data type can be nested in a single formula.
