PROBLEM
When adding global IDs to a shapefile using the Add Global IDs tool, the geoprocessing fails with the following error:
Error: ERROR 000540: The workspace is not supported.
Shapefiles use the dBASE file format (.dbf file) to store attributes. Since dBASE files do not support the global ID field type, they cannot be added to shapefiles. Global IDs are the properties of file geodatabases, feature classes, or tables.
Convert the shapefile to a feature class before adding global IDs by following the steps below.
Note: The feature class is added to the map automatically, and is shown under the file geodatabase in the Catalog window. If it is not, right-click the file geodatabase, and click Refresh.
