Troubleshooting

There are various methods of troubleshooting that can assist you in situations where when running a map, the following types of errors occur regarding input or output data:

Data is invalid
Data contains invalid objects
Unknown data exists

About data validation

When you run a map, the first thing that happens is the input data is validated by comparing the data to its definition in the schema. After validating data, the output card map rules are evaluated, and the output objects are built.

If you run a map and invalid or unknown input data is encountered, you can analyze what happened during the validation process. In addition, you can analyze the output data.
