Unique identifiers are unique combinations of alphanumeric characters assigned to each custom object record when it is created. Users can view unique IDs in the end-user interface if the identifier is set to be displayed.
You can assign unique identifiers for custom object records:
•By using auto numbering. See Creating Auto Numbering Patterns.
•By using object attributes. See Creating Unique Identifier Patterns from Object Attributes.
•By using default numbering
You can select the desired options for the project identifiers through the Unique ID tab of the respective custom object definition.
