This tutorial exercise demonstrates how to develop an Extension Operator Descriptor for a Write operator and the Record Special and Field Special settings in the Extension Object Schema Descriptor to enable the Write operator to explicity control the field order of the output records. This tutorial builds on the first tutorial exercise published on the Community site, “Schema from Type Tutorial Exercise,” and on the exercises in the online help for QlikView Expressor 3.9. Before attempting to complete this tutorial, you should have a working knowledge of the Extensions SDK and complete at least the first three tutorial exercises in the online help. You must also have worked through the Schema-from-Type tutorial.
