ETL - Tips on Linking Ports

When you develop the mapping, if you want link the ports of two transformations, You can manually link ports, or you can automatically link ports between transformations. When you link ports automatically, you can link by position or by name. I think it is easy to understand the manual way; here I just list the difference between automatica linking by position and name;

1) Automatic Linking by Position
When you link by position, the Designer links the first output port to the first input port of the another transformation, the second output port to the second input port, and so on. so the ports will be kept in the same order for the two transformations.
2) Automatic Linking by Name
Another way, You can link ports by name in the Designer. The Designer adds links between input and output ports that have the same name. Linking by name is not case-sensitive. Link by name when you use the same port names across transformations. The Designer can link ports based on prefixes and suffixes you define. Link by name and prefix or suffix when you use prefixes or suffixes in port names to distinguish where they occur in the mapping or mapplet.

you can Click Layout > Autolink in mapping or mapplet window to get more infomation.
