A "DataInvalid" error like the one shown above can occur when entering, changing or deleting a transaction. It can indicate there are duplicate entries in your company file's database (which shouldn't be there). To remove these duplicate entries and fix the error, you'll need to send your company file into MYOB tech support for repair. There's no cost involved and we'll return the repaired file as quickly as possible.
