I'm having a difficult time resolving a red "invalid" icon within Informatica. I've done all possible scenarios for checking in / checking out this object (mapping). It currently does not have any dependencies. How can I fix this?

When you validate the mapping, are there any errors in the Validate tab of the output window (at the bottom)? –  Marek Grzenkowicz Jan 30 '14 at 7:44

This was due to an incomplete mapping because my expression transformation didn't have output ports (only input ports) just before the target definition. –  MacGyver Jan 30 '14 at 19:41

What if the exchange only happens on the inbound? Do we still need to seetup an out port? –  Katia Jun 11 at 15:59
    
That's a great question. I didn't receive the error in that use case. My issue happened when a target definition was created. Are you getting this error on a source definition our something else (different object type)? –  MacGyver Jun 12 at 0:21
