I've never built a dependent function but I looked at a couple from IBM very long ago. They basically used it to change FMID ownership of modules. Modules shipped in PTF's under the parent FMID would be ignored and only the new FMID modules would replace the module. Parent is only loosely used for lack of a better term.
