Importing assemblies is almost impossible during a rebuild, I mainly run into issues with the CSV file shifting the data because of delimiters in the descriptions.  I have used an alternative option skipping the export/import option.  If you are still looking to rebuild you can contact me directly to discuss in more detail: [email protected]

We have assisted a customer with routinely importing assemblies.  The primary issues we encounter are 1) if any component in the assembly does not have adequate quantity on hand to fulfill the assembled item quantity, the import will fail.  2) Any commas in descriptions shift the import fields.  3) We use number of distributions =1.
