Problem: Calculator is not enabled for editable data outside of edit session
The ArcMap Field Calculator can be used inside and outside of an edit session. Some editable data, however, cannot be calculated outside of the edit session.
Note: The content in this article pertains to ArcGIS versions 8.x. Later versions of ArcGIS may contain different functionality, as well as different names and locations for menus, commands and geoprocessing tools.
Solution or Workaround
The following cases indicate when the calculator will be disabled
outside of an edit session.
- The field is reserved, for example cover#, objectid.
- The Data is versioned. Versioned data can be modified only in an edit session.
- The data is part of a relationship class with messaging turned on.
- The Data is the right-hand table of a join table. Only the left-hand table in a join table is editable.
