No. Documents can still be superseded or put into the Document Workflow module when they are in a Package being reviewed. Packages can also be updated while they are in a review.
Does a weighting limit apply to Package Reviews?
No. In some Workflows only so many steps, participants, and documents are allowed but there are no restrictions on how many participants and steps are in the review.
However, there are two external restrictions:
Currently Packages allow a maximum of 3000 documents, which means that the maximum amount of documents for a Package Review is 3000.
Document transmittal limits: There are restrictions in Aconex on how large a transmittal can be. Which may impact the number of users/orgs on a step in Package Reviews. See here for details on the document transmittal limit.
