Hi, as far as I know, there is no Quality Process function in Assembly Module.
But as you mentioned, you can manage this process with locations.
For example, all the finished items are moved to the location to wait for quality process. After the quality process is completed, 8 will be moved to the normal location, and 2 will be moved to the damaged/defective location.
You can use transfer order.
Hope this can give you some hints.
Thanks.
