CHAPTER 6 Components
User’s Guide 79
When stepping the component repetitively, the same set of records at the IN-
port are reprocessed in each step and forwarded to the output port without
increasing the number of the record set at the OUT-port. For many components,
the stepping can be done from inside the component window or by using the
pop-up menu from the desktop.
Managing port structures
When adding a new component to a project, Sybase IQ ETL assigns a port
structure to the newly added component based on the connecting link. Adding
a component to a project with no unconnected ports leaves the newly added
component without a port structure.
Additional attributes can be added to a port structure.
After you add a component to the project, the color of the component ports
indicates the status of the component:
• Red — no port structure is defined, one or more mandatory properties are
not defined.
• Yellow — port structure is defined, one or more mandatory properties are
not defined.
• Green — component is properly configured.

2 Select Edit Structure to open the Structure Viewer.
