Invalid Data
When a data object does not match the definition of the type to which it
presumably belongs, it could be invalid.
Following are possible reasons for an invalid data object:
♦ Item value is not in restriction list
♦ Item failed the presentation test
♦ Item is the wrong size
♦ Data object has the wrong delimiter
♦ Data object has the wrong terminator
♦ Data object failed the component rule
♦ Group is missing a required component
♦ Group contains one or more invalid component(s)
See the Map Designer Reference Guide for details on invalid data.
Summary
Trace files should be used only for debugging purposes because the trace process
impacts performance. Information in trace files can help you debug input data,
output data, and type property definitions.
Note Close all maps, type trees, and text files.
