mass checkin of files

When I do a mass checkin of SW files for the first time, the status window that pops up will sometimes have errors associated with some of the child references. ("File not found" for instance.) Is there a log file that contains this information so it can be reviewed later?

Or is there a utility that can be run against a non-PDM directory of SW files that can evaluate parent/child relationships before they get copied into the vault for the first time?

Thanks, Jason
