KB37732: "The object shown in the following hierarchy no longer exists in the schema: -Attribute: The object definition is incomplete or inconsistent" error occurs when updating schema in MicroStrategy Developer 9.4.x-10.4.

SYMPTOM:
Users might observe that the following error occurs when updating schema in 3-tier mode in Strategy Developer 9.4.x-10.4:

Error(s) occurred while loading schema: DSSSQLEngine: Schema loading error: Population Exception: The object shown in the following hierarchy no longer exists in schema: -Attribute: (xxxxx). -Attribute:The object definition is incomplete or inconsistent.

Object with ID 'xxxx' and type 12 (Attribute) is not found in metadata. It may have been deleted.
CAUSE:
One possible cause of this logical inconsistency in the metadata is that one or more attributes were deleted from the project, but references to those are still present in the attribute collection in the project schema object.
ACTION:
Contact Strategy Technical Support for further assistance. In order to track down the cause of the inconsistency, customers encountering this issue should make note of Schema-related changes, Object Migrations, or error messages prior to experiencing the problem. Change Journaling, if it has been enabled, can help in preserving this information.
