000546: Input spatial references do not match.

Description

The input feature classes must have the same spatial reference to maintain data integrity.

Solution

Reload the feature class data with the undesired spatial reference properties into a new, empty feature class with the correct spatial reference.

  • Open the Create Feature Class tool and set the Coordinate System parameter to the feature class with the desired spatial reference.
  • Use the Append tool to load the data from the feature class with the undesired spatial reference into the new feature class.

When appending annotation feature classes, use the Project tool to change the spatial reference.
