Just when you think you really know the ins and outs of SDL Tridion, surprise, here’s a neat trick from Kelly Thompson, 10 year+ Tridionaut and now Global Education Manager with SDL Web Content Management solutions.
Update (15-May 2012): This technique will push parent items through your child publication’s publication target. See Bart’s comment on how to prevent the extra items from being sent through (thanks, Bart!).
From a child publication’s publication target, set the parent publication as an allowed publication.
Now you can publish from a parent item even if its publication doesn’t have its own dedicated publication target.
Select the advanced publishing option to also publish in child publications. Selecting “Show Items to Publish” will show what’s queued for corresponding child publications.
Use target types, groups, and group scope to fine tune this to your needs. Thank Kelly for the insight.
