Globally Unique ID

The Globally Unique ID quality control (QC Quality Control) check verifies all identifiers (IDs) within a specified ID field are unique across all configured feature classes or tables. Each duplicated ID reports a fallout allowing you to spatially see the duplicate on the map with the correct feature class name populated in the fallout. The specific feature classes or tables that share that unique ID are listed in the extended information. Fallouts triggered by tables contain no latitude or longitude coordinate information, and therefore, are summarized into one record for that table's non-unique IDs.

To run this check, two or more feature classes or tables are required.

There are no parameters that can be configured for this QC check.

The following information is included for this QC check's fallout output.

  • QC check name
  • Description of the QC check
  • Unique ID as is defined in the source data
  • Latitude and longitude for feature classes only
  • Extended information providing more details about the fallout

The example below shows data that will or will not produce error messages when a record fails the Globally Unique ID QC check.
