When you start to create your own custom metrics and attributes, you'll use functions a lot to help you perform comparisons, calculations, and manipulations to your business information.
Explore offers many functions to help you work with, for example, dates, text strings, calculations and more. Use this article as a reference to help you discover the available functions and how to use them.
This article contains the following topics:
Getting started
You can browse for, and select functions when you create a standard calculated metric or attribute. In the formula editing window, you can either begin to type the name of a function or click Add under Functions and choose your function from the list.
When the function is added to a formula, it will appear with standard values. You must replace these with the values you want to use in your formula. In this example, you want to return only your tickets with subject lines beginning with "[Flagged]".
 In the calculations menu (), click Standard calculated attribute.
 Name your calculated attribute. This example uses Subject begins with [Flagged].
 Under Functions, click Add.
 In the formula window, type IF .
 Under Functions, click Add.
 Search for LEFTPART. Either use the search box, click Filter to scope the values down to the Text category, or scroll through the list until you find the function you want.
 Next to LEFTPART, click +.
 You'll now see the formula IF LEFTPART(_text,_number). Change the
_text parameter to the Ticket Subject attribute. Either highlight
_text and then choose Ticket subject from the Fields
menu, or amend the formula manually to add the attribute.
The formula will now read IF LEFTPART([Ticket subject],_number)
 Change the text _number to the number of characters you want to compare.
[Flagged] has nine characters, so enter 9.
The formula will now read IF LEFTPART([Ticket subject],9)
 Finally, add the condition we are searching for; in this case, the text
"[Flagged]". The final formula will read:
IF LEFTPART([Ticket subject],9)="[Flagged]" THEN [TicketID] ENDIF
Now, when you use this attribute in your report, it will only return tickets with a subject line beginning "[Flagged]".
For more help and examples, see Writing Explore formulas.
Basic mathematical operators
In addition to the above functions, you can also use the following basic mathematical operators to perform calculations and connect text:
Operator  Description 
+  Add two numeric values, or join two text strings. 
  Subtract one value from another. 
*  Multiply two values 
/  Divide one value by another 
=  Test if one value is equal to another value 
!=  Test if one value is not equal to another value 
> 
Test if the first value is greater than the following value (x>y) 
< 
Test if the first value is less than the following value (x<y) 
>= 
Test if the first value is greater than or equal to the following value (x>=y) 
<= 
Test if the first value is less than or equal to the following value (x<=y) 
%  Computes the modulo (or remainder) after dividing one value by
another. Example: 5%2 returns 1, 20%3 returns 2 
Logical functions
These functions give you great flexibility in analyzing and presenting your information just how you want.
Function  Description 
IF THEN ELSE Conditional expression  Enables you to evaluate logical values. Format: IF (condition) THEN (value if true) ELSE (value if false) ENDIF For indepth information about this function, see Using the IF THEN ELSE function. 
AND  Returns TRUE if the two supplied expressions are
TRUE. Example: IF ([Ticket channel]="Email") AND ([Submitter email]="fred@fredco.com") THEN [Ticket ID] ENDIF Returns all tickets that were received via. email from fred@freedco.com. 
OR  Returns TRUE if at least one of the supplied expressions is
TRUE. Example: IF ([Ticket channel]="Email") OR ([Ticket channel]="Voice") THEN [Ticket ID] ENDIF Returns all tickets that were received through either the email or voice channels. 
NOT  Reverses the logical value of the supplied
expression. Example: IF NOT([Ticket channel]="Email") THEN [Ticket ID] ENDIF Returns all tickets that were not received through the email channel. 
TRUE  Returns the logical value "TRUE". 
FALSE  Returns the logical value "FALSE" 
IN(_param,_array)  Returns TRUE if the first entered parameter is in the array specified
in the second parameter. Examples: IN(200,ARRAY(100,200,300,400)) returns TRUE IN(250,ARRAY(20,40,60,80)) returns FALSE 
SWITCH Conditional expression  SWITCH provides an easiertounderstand alternative to IF THEN ELSE
statements that have multiple branches. SWITCH (_tested_element) { CASE _value1: _return_value CASE _value2: _return_value DEFAULT: _default_return_value } For indepth information about this function, see Adding multiple conditional expressions with SWITCH. 
Attribute functions
These functions let you perform basic operations to quantify the number of attributes returned by your report. You can also perform more advanced operations to "lock in" or extend the aggregation level of your calculations.
Function  Description 
COUNT_VALUES(_attribute)  Counts the number of values of the attribute you supply. Repeat values
are included. Can be used as a condition in calculated attributes and
metrics, but cannot be used in the THEN clause of a calculated
metric. Example: IF COUNT_VALUES([Ticket ID])>30 THEN 1 ELSE 0 ENDIF The example above returns 1 when there are more than 30 tickets, and 0 when there are fewer than 30.
Tip: If you want to create a metric
that counts the number of the values of an attribute, the metric
formula should be simply [Attribute]. You can then apply the COUNT aggregator
as normal.

DCOUNT_VALUES(_attribute)  Counts the distinct number of different values of the attribute you
supply. Can be used as a condition in calculated attributes and metrics, but
cannot be used in the THEN clause of a calculated metric. Example: IF COUNT_VALUES([Organization name])>100 THEN 1 ELSE 0 ENDIF The example above returns 1 when there are more than 100 distinct organizations, and 0 when there are fewer than 100.
Tip: If you want to create a metric
that counts the number of distinct values of an attribute, the
metric formula should be simply [Attribute]. You can then apply the D_COUNT
aggregator as normal.

ATTRIBUTE_FIX(aggregator(metric name), attribute1, attribute2) 
Returns the value of aggregator(metric name) aggregated by the attributes you specify (in this example attribute1 and attribute2). No other attributes can affect the results from this metric. Calculated attributes can’t be used inside of the ATTRIBUTE_FIX function. Example: ATTRIBUTE_FIX(MED(First Reply Time (min), [Ticket created  Year], [Ticket created  Month]) For more help and examples, see Working with aggregation level functions. 
ATTRIBUTE_ADD(aggregator(metric name), attribute1, attribute2) 
Returns the value of aggregator(metric name) aggregated to all attributes in the report in addition to attribute1 and attribute2. Calculated attributes can’t be used inside of the ATTRIBUTE_ADD function. Example: ATTRIBUTE_ADD(MED(First Reply Time (min), [Ticket created  Year], [Ticket created  Month]) For more help and examples, see Working with aggregation level functions. 
Tag functions
These functions help you search for the presence or absence of tags. This can include ticket tags, call tags, or anything else that uses tags.
Function  Description 
INCLUDES_ALL([tag attribute], "tag1", "tag2")  Returns TRUE if all of the specified tags are included in the tag
attribute. Examples: INCLUDES_ALL([Ticket tags], "London", "Milan") returns TRUE if a ticket contains the tags "London" and "Milan". NOT INCLUDES_ALL ([Ticket tags], "London", "Milan") returns TRUE if a ticket does not contain both of the tags "London" and "Milan". For more examples of how to use this function, see Reporting with tags. 
INCLUDES_ANY([tag attribute], "tag1", "tag2")  Returns TRUE if any of the specified tags are included in the tag
attribute. Examples: INCLUDES_ANY([Ticket tags], "London", "Milan") returns TRUE if a ticket contains the tags "London" or "Milan". NOT INCLUDES_ANY ([Ticket tags], "London", "Milan") returns TRUE if a ticket does not contain either of the tags "London" or "Milan". For more examples of how to use this function, see Reporting with tags. 
Text functions
These functions enable you to perform operations that search and evaluate text. You can also modify text using formulas and patterns you create.
