Cognos Tutorial Overview

This tutorial demonstrates how to insert a barcode into the report through the DataItem. The example assumes a database is already created and that the Dynamic Barcode Generator Service demo URL will be used. The fields for this example include Product Number, Product Type, Product Name, and Description. An additional field using the Product Number, which will be converted to the barcode by setting the D (Data To Encode) parameter, will be added as the last column.

IDAutomation's streaming barcode products may be customized according to the available parameters.
