Narrator runs a series basic tests to ensure all transformations will process correctly. After you save a transformation, you'll be able to run validation.
These tests check the core assumptions that are used when updating the activity stream, customer, and enrichment tables. When these assumptions fail then the data doesn't process correctly, so the validation step will help catch processing issues before you merge to production.
Validation tests required
Check for LIMIT Clauses
LIMIT is not used to limit the data output of the transformation
Check for Missing Columns
All required columns are available
Check for NULL Values in Required Columns
Check for ID Duplication
Note: Additional tests can be manually run on the transformation from the Validation Log tab. More information on the additional validations can be found here.
