A password protected file can cause what type of error?

A password protected file can lead to a document-level error because such an error typically occurs when there is an issue specific to a particular document or file that prevents it from being processed correctly. When a file is password protected, it becomes inaccessible without the correct credentials, which means that the processing system cannot read or analyze the file as intended.

This situation specifically impacts that document and not the overall job or processing set, which contain multiple files or tasks. Therefore, the focus on a particular document's inability to be accessed due to password protection clearly delineates it as a document-level issue rather than affecting the entire job or creating a processing set error.
