This is most definately a good idea, and a most welcome one.
By my estimates, duplicates arise in the following situations:
1- Equipment owner moves from an existing system to Onix, manually inputting items at first, and then requesting documentation from previous system once Onix starts to get familiar.
2- Inspectors perform inspection on equipment, but due to misspelling, system errors, filter settings, or other complications, cant find the already established equipment, and creates a new listing in order to register the inspection job. (same can also be case for personnel performing maintenance or other equipment specific tasks).
Seeing as merging equipment listings would potentially have a severe impact on the database as a whole, for the specific equipment owner, the merging of equipment listings is something i would prefer to be a task only available to personnel given that permission in account type settings by the admin.
The merging feature is the #1 on my list of features i would love to have in Onix.
You are both correct, this is a feature that would help a lot of customers.
I will bring it forth in our product group and keep you updated on any progress on this topic.
