every time I try to browse new training in the learning portal my browser crashes and my PC performance goes to 💩 Anyone else having the same issue?

You must be using serialized inventory (or similar), and in that case, the inventory detail information must be provided either on the Item Fulfillment, or on the Sales Order if you are not going through a fulfillment. Try doing it in the UI, and I think you'll get the same error.

wrong thread?

yes, sorry 🙂

no worries

JC, what training are you having trouble with?

Some years ago when I did a few of them, I noticed that some of them only worked fine using IE. Not sure if that has changed. Even some PDF guides were only downloaded from IE if not the browser crashes as well.

@eminero literally! I changed to IE and it works fine
