Deleting and Undoing Translation Performance Datasets 
You can undo and delete one or more translation performance datasets for a particular target language.
When you select a translation performance dataset and choose Undo, the system deletes the translation performance dataset without deleting the translation performance data that belongs to it. You can then use the translation performance data as part of a new translation performance dataset for a different period.
When you select a translation performance dataset and choose Delete, the system deletes the translation performance dataset and all translation performance data that belongs to it from the database.
To be able to do this, the following roles must be assigned to your system user:
SAP_TRANSLATOR
SAP_TRANSLCOORD
SAP_TRANSLSUPERCOORD
SAP_TRANSLENV_ADM
