Evaluates a CTL expression and rejects validated record when the result is false.

	Note
	Filter expression editor helps editing the CTL expression.

Checks if a value is present or missing in a lookup table.

The rule can be found in Basic rules.

	Rule usage example
	Product code is a valid product code from the table. Consider all record not having corresponding product code in the lookup table as invalid.

Rule Is Date checks string field to be in desired date and time format. See Date and Time Format

The rule can be found in String rules.

	Rule usage example
	Check start date to be in format yyyy-MM-dd.

	Note
	Functionality of date validation depends on correct locale and timezone settings. See Locale and Time Zone.

	Important
	If you have date in the yyyyMMdd format (e.g. 20150111) and you need to have exactly 8 characters, use Strict validation from Locale and format settings to check date correctly. Otherwise 2011011 would be considered as valid date corresponding to the mask. The date would be interpreted as 2011-01-01.

Rule Is Number validates field to have a desired numeric format.

The rule can be found in String rules.

	Rule usage example
	Weight must be an integer.

Rule String Length checks the length of the string.

The rule can be found in String rules.

	Rule usage example
	Login name must have at least 3 characters. The maximal allowed length is 20 characters.

The Pattern Match rule checks whether the field corresponds to a regular expression.

The rule can be found in String rules.

	Rule usage example
	Check the name to begin with letter A and to be formed by at least 3 letters.

	Note
	If your regular expression does not match the string and you expect that it should match, you probably need pattern flag, e.g. (?s).*. See Regular Expressions

The Enum Match rule checks a field to contain one of values from a predefined set of values.

The rule can be found in String rules.

	Rule usage example
	Field must have value of "A" or "B".

The Email Address rule checks a field to be valid email address. Valid email address means an email address in correct format. It does not mean existing email address.

The rule can be found in String rules.

	Rule usage example
	Check that field senderEmail contains valid email address.

The Phone Number rule checks a field for a phone number in correct format.

The rule can be found in String rules.

Furthermore the rule can convert a validated phone number to a specified format.

1) (201) 555-5555 is a valid US number, but so is +420 777 777 777 - it is a valid international phone number that you can dial from the US.

2) Usage: D substitutes any digit. You can also specify allowed repetition count with {min,max} pattern.

3) The following output formats of phone numbers are available:

	Rule usage example
	Phone number has to be valid US number with leading international prefix.

Copy copies a value of an input field to another output field.

The rule can be found in Assignment rules.

	Rule usage example
	Copy a content of the field startDate to the field startDateStr.

Transform can be used to produce custom output values.

The rule can be found in Assignment rules.

	Rule usage example
	Copy a group of input fields to a different group of output fields based on which branch of validation tree (group of rules) was successful.

Copy all fields by name copies all input fields onto output fields having the same name and type.

The rule is added as a first rule in a tree of active validation rules, by default. The rule should not be put after any rule assigning values to output fields as it would overwrite all the output values produced by rules above it.

The rule can be found in Assignment rules.
