The External ID of '14439163' for Evidence Item 'SQ-5.1.1(a)' does not match the value '14504210' expected by the import (row 2)
Check the failed import logs (event log) to identify which envelopes have been brought over initially and which supplier envelopes have been passed across.
This could be as a result of bringing over one envelope within the Evidence items import and the other being a selection of all envelopes within the Supplier response import. eg you bought over Technical in the evidence items transfer, but bought over Technical and Qualification in the supplier import.
To correct; reimport using the right envelope combination.
