Using the Lookup operation
Use lookup tables to define lists of 'transformed output values' dependent on ranges of source data.
Note: Lookup functionality uses alpha collation only, that is, alphabetically ordered
text strings. It is not recommended to use lookup tables for ranges of numeric data,
such as dates, journal numbers of financial amounts.
Note: The required lookup table must already exist. You can create lookup tables using
Lookup Table Designer in Transfer Desk.
