Logical connections

Logical connections

A logical connection is a name used to represent a shared connection.
Use a logical connection when you want to use the same connection for more than one connection template parameter in a Visio template. To use a logical connection, enter the same logical connection name for all template parameters that you want to use the same connection.
When you use logical connections for connections that display on a single page of the
mapping
task wizard, the wizard displays a single connection for the user to select.
For example, you might use a logical connection when a Visio template includes two sources that should reside in the same source system. To ensure that the task developer selects a single connection for both sources, when you upload the Visio template, you can enter "Sources" as the logical connection name for both source template parameters. When you create a
mapping
task, the
mapping
task wizard displays one source connection template parameter named Sources and two source object template parameters.
When you use a logical connections for connections that display on different pages of the
mapping
task wizard, the wizard uses the logical connection name for the connection template parameters. If a logical connection appears on the Other Parameters page, it displays in the Shared Connection Details section. Since the requirement to use the same connection for all logical connections is less obvious, you might configure a lookup to display on the same wizard page as the other logical connection, or use descriptions for each logical template parameter to create tooltips to guide the task developer.
You can use any string value for the logical connection name.
