Reorder Generated Ports

Reorder Generated Ports

You can reorder generated ports through a setting that reorders the ports based on the order of input rules or the ports in the Read transformation. By default, the Developer tool displays the generated ports in the same order that they appear in the upstream transformation.
You can choose one of the following options to reorder generated ports:
Upstream group or dynamic port
Display the ports in the same order that they appear in the group or the dynamic port of the upstream transformation. This is the default option.
Input rules
Display the generated ports based on the order of the input rules for the dynamic port.
The Data Integration Service reads rules in the order listed in the
Input Rules
 dialog box. Review the port order and reorder them based on the order of the input rules. You can ensure that the Data Integration Service processes ports and rules in the order that you require. Reordering the ports also helps you view and analyze results.
Nearest transformation with static ports
Display the generated ports based on the order of the ports in the Read transformation.
Reordering ports based on this option helps you retain the original order of ports in the source. However, if one or more mid-stream transformations have dynamic ports and static ports, the Developer tool displays the ports in the order that they appear in the nearest upstream transformation with static ports. This option is valid only if the mapping has a single pipeline.
