Generate UUID -> Function result 
Parameter Type   Description
Function result  String in New UUID as non-canonical text (32 characters)

The Generate UUID returns a new 32-character UUID identifier in non-canonical form.

An UUID is a 16-byte number (128 bits). It contains 32 hexadecimal characters. It can be expressed either in non-canonical form (series of 32 letters [A-F, a-f] and/or numbers [0-9], for example 550e8400e29b41d4a716446655440000) or in canonical form (groups of 8,4,4,4,12, for example 550e8400-e29b-41d4-a716-446655440000). 

In 4D, UUID numbers can be stored in fields. For more information, please refer to the UUID format section of the Design Reference manual.
