If you receive the following error in SAP B1, you may be able to resolve the issue by Restoring the Numbering File:
“This entry already exists in the following tables”.
The table being referenced can vary with this error message but the fix remains the same.
- Ensure your Database has a recent backup to revert to in case restoring the Numbering File has an adverse effect.
- Ensure all users are logged out of the DB before restoring the Numbering File.
- Go to Help->Support desk->Restore->Restore numbering file
