Clients are always asking me why the contents of portals do not duplicate along with a record. It makes sense. Portal data looks like it's part of the parent record so it should duplicate just like the local fields, right? After explaining how relationships work, the client still wants the related data to duplicate. The great thing is, the script isn't that difficult to write. There's just a few gotchas, opportunities for efficiency and, of course, the patented Philosophy of FileMaker considerations.
