If more than one document is found that meets the rendition criteria, then the imported document will become a new document in the system (not a rendition of either matching document) and an error entry listing this document will be included in the verification report.
A document can only have one rendition with a particular file format. If a second rendition of the same file format is attempted, the second rendition will overwrite the first.
If you are adding multiple revisions/renditions in one complete DIP process, then you must adhere to the revision rule of ordering the revisions from oldest to newest in the DIP file. This will build the proper revision/rendition order of documents that you want in the system. If the records are not properly ordered, then the document will not be constructed as desired.
