How Can We Help?
You cannot save these changes.
Sage 50 “You cannot save these changes” message.
This error may be many different issues. Make sure you are not trying to edit an archived company. You can tell this by looking at the Sage 50 program title bar. Make sure it does not say Archived (company name), you cannot edit an archived company.
If you are not working with an archived company then your company’s DDF (Data Dictionary Files) may be damaged. The DDF files provide the database schema (database layout) to the Sage 50 database.
You can delete these files and Sage 50 will create a new set for you when you open your company again.
Always backup your company’s data prior to deleting any files. We cannot stress this enough. If you delete the wrong files by error you can easily get them back by restoring.
How to delete your DDF Files
Locate your company data folder. If you are running Sage 50 2021 you may find this on the open company dialog. If you are running an older version. Open the company, from the top menu select Maintenance, and select Maintain Company Info.
Once you have your company’s data location at hand, close the Sage 50 program. Make sure any additional users have the company closed as well. The company cannot be in use when we are going to delete the DDF files.
Open Windows File Explorer and navigate to the data folder above.
Delete all the DDF files.
Restart Sage 50 and open the company. You should see a flash dialog showing that it is recreating the DDF files.
That’s it. Now see if the message “You cannot save these changes.” has stopped.
