Use the Term Lookup tab of the Term Lookup Transformation Editor dialog box to map an input column to a lookup column in a reference table and to provide an alias for each output column.
Using the check boxes, select input columns to pass through to the output unchanged. Drag an input column to the Available Reference Columns list to map it to a lookup column in the reference table. The input and lookup columns must have matching, supported data types, either DT_NTEXT or DT_WSTR. Select a mapping line and right-click to edit the mappings in the Create Relationships dialog box.
Available Reference Columns
View the available columns in the reference table. Choose the column that contains the list of terms to match.

Output Column Alias
Type an alias for each output column. The default is the name of the column; however, you can choose any unique, descriptive name.
