Function	Description
Add	Adds two numbers.
After	Returns Boolean value indicating whether the first date is later than the second.
And	Returns Boolean value indicating whether or not both conditions are true.
Before	Returns Boolean value indicating whether the first date is earlier than the second.
BitAnd	Applies a bitmask on a flag to 0.
BitNot	Inverses each bit.
BitOr	Applies a bitmask on a flag to 1.
Concatenate	Concatenates two or more strings.
ConcatenateMultivaluedString	Used to generate a string which represents multiple string values.
Contains	Returns Boolean value indicating whether the value exists in the list of values. String comparisons will be performed without case sensitivity.
ConvertFromBase64	Converts a base64 string to a byte array
ConvertSIDToString	Converts a byte array containing a security identifier to a string.
[ConvertStringToGUID / ConvertToGUID][ConvertStringToGUIDFunction]	Converts the string representation of a GUID to a binary representation of the GUID.
ConvertToBase64	Converts a byte array to a base64 encoded string.
ConvertToBoolean	Converts a string or a number to a boolean value.
ConvertToNumber	Converts a string or a boolean value to a number.
ConvertToString	Convert a value to its string representation.
ConvertToUniqueIdentifier	Converts all supplied guids to a unique identifiers so they can be used in native FIM activities such as the Approval activity.
Count	Returns the number of entries in a list. If an object is passed (single string or resource ID, for example), the count will be 1. If a null value is supplied, the count will be 0.
CRLF	Generates a Carriage Return/Line Feed.
DateTimeAdd	This function can be used to add/subtract a timespan to/from the supplied date/time.
DateTimeFormat	Formats the value of the first DateTime parameter in the format specified in the second string parameter.
DateTimeFromFileTimeUTC	Converts the specified Windows file time to an equivalent UTC time.
DateTimeNow	Returns the current date/time in UTC.
DateTimeSubtract	Converts a date in the Windows file time format.
DateTimeToFileTimeUTC	Gets the timespan between the two dates.
Eq	Determines the equivalence between two objects or values and returns true if they are equal.
EscapeDNComponent	Escape the DN component of a distinguished name specified in LDAP format.
EvaluateExpression	Evaluate the specified expression. The caller activity must read the all lookups used in the expression separately.
First	Returns the first value in a list.
GenerateRandomPassword	Generates an alphanumeric password of the specified length.
GreaterThan	Returns Boolean value indicating whether the first integer is greater than the second.
IIF	Return the second or third parameter based on the evaluation of the condition specified as first parameter.
InsertValues	Used with the Update Resources activity to specify that a value or list of values should be inserted into a multivalued target attribute.
IsPresent	Returns false if the supplied value is null. Returns true if it is not.
Last	Returns the last value in a list.
Left	Returns he leading substring of specified length. If the specified length is greater than the input string, the entire input string is returned.
LeftPad	Returns a new string that is equivalent to string specified in the first input parameter, but right-aligned and padded on the left with as many padding characters as needed to create the specified length.
Length	Returns the length of the string.
LessThan	Returns Boolean value indicating whether the first integer is less than the second.
LowerCase	Converts all characters in a string to the lower case based on current culture.
LTrim	remove leading white spaces or specified characters from a string.
Mid	Returns a specified number of characters from a specified position in a string.
NormalizeString	Normalizes the first string, first by replacing the character substitutions specified in the second string and then removing all diacritics using the .NET string normalization function.
Not	Flips the Boolean value of the supplied condition.
Null	Returns a null value. You can use this function in Update Resources with the "Allow Null" checkbox to clear the value of an attribute.
Or	Returns Boolean value indicating if either condition is true.
ParametersList	When supplied the request parameters for a request (for example, [//Request/RequestParameter]) and an attribute name, returns a Boolean value indicating if the attribute was modified by the request.
ParametersContain	Returns the list of attribute names in the request parameters of an arbitrary request
ParametersTable	Returns a table of attribute name, modification type and modified values in the request parameters of an arbitrary request
ParameterValue	Returns the value of a request parameter of an arbitrary request. When the request is for an update of a multi-valued attribute, ParameterValueAdded() and ParameterValueRemoved() must be used.
ParameterValueAdded	Returns the added values of a multi-valued request parameter of an arbitrary request.
ParameterValueRemoved	Returns the removed values of a multi-valued request parameter of an arbitrary request.
ProperCase	Converts the first character of each space-delimited word in a string to upper case and all other characters are converted to lower case.
RandomNum	Sorts the specified List.
RegexMatch	Splits the string into substring delimited by the specified separator.
RegexReplace	Subtracts the second integer value from the first.
RemoveDuplicates	Returns a random number within a specified interval.
RemoveValues	Returns a Boolean value indicating if the string matches the regex pattern.
ReplaceString	Replaces the regex patter with the specified string.
Right	Removes duplicate values from a list of items.
RightPad	Used with the Update Resources activity to specify that a value or list of values should be removed from a multivalued target attribute.
RTrim	Replaces all occurrences of a string to another string.
SortList	Returns a trailing substring of specified length. If the specified length is greater than the input string, the entire input string is returned.
SplitString	Returns a new string that is equivalent to string specified in the first input parameter, but left-aligned and padded on the right with as many padding characters as needed to create the specified length.
Subtract	Removes trailing white spaces or specified characters from a string.
TitleCase	Converts the specified string to title case (except for words that are entirely in uppercase, which are considered to be acronyms).
Trim	Removes leading and trailing white spaces or specified characters from a string.
