Can't copy from a read only field

[Max C1]

Our non admin itil users receive an error when they try to copy information from the long description field. I don't understand why it won't allow them to copy info from the field. I figured possbily the acl rule to write was involved. 

Anyone able to help?

Below are some screenshots.

Hi,

You have it as data policy exception on that table.

That shows up when they simply try to copy from the field? Says invalid update as well?

Please mark reply as Helpful/Correct, if applicable.

Thanks!

Yes, that's correct.  When I or another admin performs this we do not get the same result.  Just copying anything from the read only field seems to cause the error, you don't even have to paste it.

Can you look in to the data policy you have set? Temporarily try to inactivate it, try again and see if it works? I think it's the data policy doing it. No matter what ACL is on it.

Go to the record, right-click gray header at top, choose Configure > Data Policy and you should see the record there to inactivate just to check and see.

Disabled and re enabled. I agree this is probably the cause, I just don't understand why.
