I've tried many variations.
- Send To Library - That creates a Zipped file in the Drop Off Library, then it doesn't route via the rules in Content Organizer
- API - I've tried to do an Export, Import, but always receive the same error. This is per this MSDN documentation: http://msdn.microsoft.com/en-us/library/microsoft.office.documentmanagement.documentsets.documentset.create.aspx
Sample snippet:
byte[] exportedFile = set.Export();
DocumentSet.Import(exportedFile, DocSetNameToCreate, targetFolder, dsCt.Id, properties, web.CurrentUser);
Error Received:
DocID: Site prefix not set.
