Mapping validation

Each time you save a mapping, the Mapping Designer validates the mapping.
When you save a mapping, check the status to see if the mapping is valid. Mapping status displays in the header of the Mapping Designer.
If the mapping is not valid, you can use the Validation panel to view the location and details of mapping errors. The Validation panel displays a list of the transformations in the mapping. Error icons display by the transformations that include errors.
In the following example, the Accounts_By_State Target transformation contains one error:
Tip: If you click a transformation name in the Validation panel, the transformation is selected in the Mapping Designer.
Due to processing differences, the Validation panel shows additional validation errors for some transformations in elastic mappings. The validation errors result from validation criteria on the Serverless Spark engine.
