when I worked for the IT Department we had to assume that managers and other Non-IT staff knew nothing about technology.

In that case I would have said:

"IBM has documented that if we apply this fix, it will make the '#Name' in our attached tables go away and be replaced with actual information that should be there. User1 and User2 need this fix and it should be applied as soon as possible to get back to normal operations."

You have to provide the link, which to him/her is technobabble, but if they can see that it says "download this file for a fix..." and you write to them at a 6th grade level as to why the problem exists as I did above, they might just understand you.
