When attempting to open a Classification Group within the Transformation Designer, the following error is encountered:
Unknown Error: An error occurred while saving the document set. Error: constraint failed UNIQUE constraint failed: XXX
The actual root cause of this issue was never determined.
The following steps is a workaround to resolve this issue. It is recommended to backup any training sets first.
- Remove one of the Extraction Groups (EG) that are linked to the problem Classification Group (CG) within the KTA Designer and then release it.
- Problem CG should now open in the Transformation Designer and re-release it.
- Then in the KTA Designer, readd the removed EG to the CG that was done in Step #1 and release it.
- Open CG in the Transformation Designer and re-release.
