Base files store the reference file paths in the header. During the auto-resolve process, Primavera Unifier reads the path in the header and then looks for the reference files based on this path. If the reference file path cannot be read, or if the reference files cannot be found in the path specified by the header, the references are flagged as missing.
Note: Nested reference files are not supported. For example, a base file references a reference file, which in turn references another reference file (that is, the first reference file is a base file for the second). Primavera Unifier does not try to resolve missing nested reference files.
You can resolve missing reference files during or after uploading into Primavera Unifier. You can resolve missing references within the Document Manager in several ways: manually upload a missing file from your computer; link to a reference file that is already in project or shell or company documents; or let Primavera Unifier attempt to auto-resolve it by searching for the missing reference.
Note: The auto-resolve process will search for the missing attachment in the Primavera Unifier folder path as defined in the base file header and in the same folder as the base file.
