We have a metadata field where the Everyone group only has read-only access to it, so if you go into the repository and select a template containing it on an entry, the field will show as greyed out.

However, in Scanning, if you select the same template, the field shows as normal and you can fill in a value. However, trying to scan in the file with that metadata filled in will throw an error with "One or more required fields were omitted or had a blank value. [9066]"

We had a support case about this and resolved it by making it so the field is no longer read only, but when the field was read-only, should it not have shown as greyed out in Scanning? Does Scanning not work that way?
