KB489586: "The object shown in the following hierarchy no longer exists in schema: -Relation-Attribute:Object is not found in DFCSchema during DFC conversion." Error When Updating a Project Schema

Symptom 1: Project Schema Update

When performing a project schema update in Workstation, the following error displays:

Error(s) occurred while save and updating schema: Intelligence Server Gateway Error: (Error(s) occurred while loading schema: [DFCSCHEMA] Population Exception: The object shown in the following hierarchy no longer exists in schema: -Relation-Attribute:Object is not found in DFCSchema during DFC conversion. 3C538B53DDC84985B222F0E8F2D45348 DSSSQLEngine: Schema loading error: Message from GetErrorInfo : Index out of range in method 'IDSSTemplate::Item'.)

Symptom 2: Project Schema Reload

When reloading a project schema in Workstation, the following error displays:

Encounter the error when reloading the schema: Schema reload is taking longer for larger schemas and will continue running in the Intelligence Server. During this time, the schema will appear as locked.

Cause

This is a metadata inconsistency as time attributes created using the Save As option in Workstation are not added to the schema object, therefore schema updates fail.

Action

Delete attributes created using the Save As option and use Copy instead.
