It's been found after testing that the actual durations of the imports performed were about 2 (two) times longer than what was reported. This is due to the PTF environment missing a DB trigger that, when restored, doubled the imports' durations.


Overview 

This is a test report of MARC Authorities Data Import running on the Morning Glory software.
