** Run this tool from ArcCatalog, and do not have the feature class / table opened anywhere else.
The Creates Unique IDs tool adds a field called UID and creates a unique ID for each record of an input feature class or table. The unique IDs can be grouped based on a common field attribute and also sorted in ascending or descending order. A prefix and suffix can also be added.
There are currently 3 different techniques to create the unique IDs:
UNIVERSALLY UNIQUE IDENTIFIER – random 32 characters, xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
RANDOM WITHIN RANGE – unique random numbers within a defined range
INTERVAL – based on a user defined interval
Be sure to view the Tool Help within the tool dialog box for detailed instructions. Also, check the Geoprocessing Results for any error messages.
