Code. A code (for documents, a number) is a mandatory configuration object attribute.
Depending on the application, an item code can be assigned automatically or manually when the item is created.
If automatic numbering is defined for a specific object, once an item of this type is saved, the code or number field is filled with an automatically generated code or number. You can edit the code or number. Codes or numbers must be unique within a single object type.
If you attempt to enter a duplicate code or number, the application displays a warning.
Prefix. Codes or numbers can have prefixes. When an item is created, the code or number suggested for that item includes the prefix. However, you can completely change the suggested code or number, including its prefix.
