# Day Rebuilder ### Day Rebuilder The Day Rebuilder option allows to cancel the day and re-enter every transaction one by one to recreate the day. Use only this option when you have problems with the Back-Office. If this option is needed, call Maitre'D support. **First Backup,Second Backup** The Back-Office keeps two copies of all transactions in MEMOIRE.DAT files. The first backup is located in the REBUILD directory and the second backup is located in the BACKUP directory. Select first non-corrupted backup file. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
