The output created or modified has no features. For instance, running Delete Features or Delete Rows on a feature class or table would remove all features. This warning commonly occurs when the Extent or XY Domain environment was previously set for a geographically distinct area. Since the Extent environment is used to limit features, an inappropriately set Extent environment could exclude all features.
If this warning is unexpected, check the Extent or XY Domain environment to ensure that it is appropriate for the data used.
