Cognos Sync Utility Error: BMT-MD-0006 Another object of type 'Query Subject' already exists with the name 'XXX' in Namespace 'YYY'
REASON
The Cognos model and the Changepoint udf tables are out of sync. Changepoint thinks there is a new custom field and tries to add it to the Cognos data model, but it already exists there.
RESOLUTION
1. Import the base model (model.zip or model-ITD.zip)
2. Create a new revision
This will rebuild all custom fields in the Cognos data model.
Note: Depending on the number of custom fields, this process can take a long time (hours).
