Flat File Lookups

Flat File Lookups

When you create a Lookup transformation using a flat file as a lookup source, select a flat file definition in the repository or import the source when you create the transformation. When you import a flat file lookup source, the Designer invokes the Flat File Wizard.
Use the following options with flat file lookups:
  • Use indirect files as lookup sources by configuring a file list as the lookup file name.
  • Use sorted input for the lookup.
  • Sort null data high or low.
  • Use case-sensitive string comparison with flat file lookups.
