Is there a warning/error screen for trying to adjust qty from the previous month?

Hello, SAP community! I was wondering if there is an error message or warning screen that will display when trying to adjust a previous months quantity/SLOC I've seen it before where SAP will display "Can't adjust prevous month etc" I need to know how to bring this screen up.

Maybe I came off as confusing. When going into a new month, adjusting the stock count, changing the sloc would prompt a warning message from SAP, that states this can't be done.
