Note

After the quality dimension table is created, the data of the model and attribute in the dimension table can immediately be used in assessment rules. The latest configuration information in the dimension table will be synchronized at 02:00:00 every day in the UTC+8:00 time zone of the current application user’s computer, and will directly overwrite the original ones.

  • If the model is deleted, the Model field in the corresponding quality dimension table shows empty.
  • If an attribute of the model is deleted, the attribute data in the quality dimension table shows empty, but the assessment rules linked to the attribute are not affected.


After a quality dimension table is created, you can view the dimension table information in the list on the Quality Dimension Table page.
