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?
This was due to an incomplete mapping because my expression transformation didn't have output ports (only input ports) just before the target definition.
I would like to had a general guide to debugging "invalid" object in PowerCenter.
Indeed as the debugger from the PowerCenter Workflow does not run on invalid Mapping(I would say in general does not run on invalid objects), the only way to get more information is to go on the repository Manager and follow this steps:
Open the specific folder
Right-click on the object and try before to refresh( this will make sure any change not saved will be saved), then choose "Validate", at this point teh Repository Manager will try to validate the object otherwise finnally you will get an error message reporting what is causing the invalidation.
