Unable to check in files due to Error“You must fill out all required properties before checking in this document.”

Question

I receive this error "You must fill out all required properties before checking in this document." while trying to check in a file. I tried fill up all the properties for the file but still receiving this error. Anybody knows why?

Answer 1

1. Go to the list settings > Advanced settings > change it to No for "Allow management of content types" (don't worry it won't remove any content types).
2. Then set ALL the columns to non-required in the column settings.
3. Turn the Allow management of content types back on.
4. Go into each content type, set each column to require/optional/hidden there.

Answer 2

These are required columns (the * asterisk indicates a required field). You will not be able to save unless each required columns has a value, no blanks are allowed. Or, if you have sufficient permissions, you can edit the columns in the settings to stop columns being required - when it is no longer required it means you can save it with a blank value.
