Mapping validation

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:
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
.
