Mapping options
The mapping options define conversions that onpload applies to the data before it inserts the data into the database (for a load job) or into the data file (for an unload job). These conversions can include case conversion, text justification, data masking through picture strings, default values, and fill characters. The mapping options also allow you to replace imported data with data from other database tables.
The information from the Mapping Options window is stored in the mapoption table of the onpload database.
