Check the field and template security and make sure that the account you are using has rights to the fields and the template that they are using.

I was using an admin account.  It has full rights to the template and fields.  In the log file it references line numbers.  What are those indicative of?  It also says:  Name: "Client information", but all the documents have names, and none are named "Client Information".   If this was suppose to be the name of a template, why did it only prompt for the one template during the import?  Thanks.

From the log, it looks like you are using an xml file to do a list import.  is the data in the xml file for those that fail longer then the field in Laserfiche?

I don't mind opening a case.  But the smaller briefcase in question is 14 GB in size (the larger is 56 GB).   I was more than anything, just trying to learn what the information in the log file means.  To answer Bert's inquiry's, I was importing Laserfiche briefcase files, and posted up one of the resulting log files.   I am not aware of any xml file.  Thanks.

A Laserfiche briefcase is a .tar.gz file (tar gzipped) that contains xml files that describe the documents within the briefcase. The toc.xml file describes information such as the document name, assigned fields, and creator. The line number is likely the line number in the toc.xml file. You can use a tool such as 7-zip to view the files themselves (see the answer to this post, among many, that describe the process).

You can upload the briefcase into our ftp site after you open the case. ftp://ftp.laserfiche.com/incoming

This warning means there was a problem with the field matching for the "Client Information" template.  One of the fields in the briefcase wasn't matched to an existing field in the repository. Extract toc.xml like Brianna mentioned and check out the line numbers mentioned in the log, you might be able to see which field didn't match properly. The briefcase might not be useful to us because we are not familar with your repository.

I tried changing the extension and opening it up with 7-zip.  It keeps giving errors that it's "unsupported command".  I tried it on other .lfb files and got the same result.  There is no "Client Information" template nor field in the repository.  When the briefcase was imported, the notification came up for the 1 template that is assigned on all the documents.  When i search for any documents with no template, the search comes up empty.  I don't know how to extract the toc.xml file.  I followed the directions in the link, but I just keep getting "unsupported command" errors.  Thanks.

Thank you.  That helped a lot.  I got the process to finally work.  Unfortunately, I think I corrupted the original lfb file by changing the extension.  So I can't investigate why I got the errors to begin with.  It's no big deal though.  The project is completed, so there is no need to open a ticket.  The purpose of posting this topic was educational, for future troubleshooting.  I thank everyone for their input.
