FAQ: Is it possible to enable or add attachments to a geodatabase feature class?
Is it possible to enable or add attachments to a geodatabase feature class?
Note: This article applies to ArcGIS for Desktop Basic license level users only.
With an ArcGIS for Desktop Basic license in ArcMap, it is not possible to enable or add attachments to a geodatabase feature class or table.
An ArcGIS for Desktop Standard or Advanced license is required when using the Attachments toolset. The Basic license only allows users to view and read the attachments.
When enabling attachments, ArcGIS creates a new table to contain the attachment files and a new relationship class to relate the features to files. Relationship classes are used to maintain linkage when using the tools in the Attachment toolset, and relationship classes can only be created with Standard or Advanced licenses. Thus, only users with a Standard or Advanced license can enable or add attachments.
Note: Users with the appropriate licensing level can enable attachments by using ArcCatalog or running the Enable Attachments tool.
