I set up a Document Library (DL) for our Accountants to upload their files. All Accountants have 'Edit' permission in DL. These files will be reviewed by the supervisor. After supervisor reviews and validate files, she/he then download and submit files to external auditor. After file submission, the folder storing these files is required to be changed to ready-only, and no one can add, delete, and edit the files in this folder. Is any possible to reach out this requirement? Your assistance will be greatly appreciated.
v/r,
