A mapping template is a drawing in Visio that represents a PowerCenter mapping. You can configure rules and parameters in a mapping template to specify the transformation logic.
Use the Informatica Stencil and the Informatica toolbar in the Mapping Architect for Visio to create a mapping template. The Informatica Stencil contains shapes that represent mapping objects that you can use to create a mapping template. The Informatica toolbar contains buttons for the tasks you can perform on mapping template.
You can create a mapping template manually, or you can create a mapping template by importing a PowerCenter mapping.
