Importing with a mapping file
You can import data through the Data Import utility by using a mapping file created in Data Import. You can use the mapping file on any platform. For more information about Data Import mapping, see Creating mapping files.
Specifying the -M or -m option in the command line determines whether you use a mapping file.
If you are copying the mapping file between different operating systems (such as Windows to UNIX), make sure that the file is converted properly so that the operating system can read the file.
You can override specific settings saved in the mapping file by using additional options. In this way, you can use the data mappings you created for one data file and destination form for imports with a different data file and form combination.
