So i already have "auto generated" columns on one of my site, but lately people have been using it wrongfully (if that's a correct word). I wanted to make couple columns required but came to find out that there is no option for me to make it required. I do not want to create new column since all the information already there i wont be able to transfer them to the new filed. so is there a way to make them required? I am guessing these fields are called "sealed"? Not sure, i am new to sharepoint.
Date: (would like to make it required)
As you may see no option to enable required nor delete. Need help.
