File/System errors
Common Causes of File/System Errors in Tally Prime:
Missing or unreported data
"Missing or Unreported Data" with file/system errors in Tally Prime means some company data is damaged or incomplete—often due to sudden shutdowns, disk issues, or file corruption. Tally can’t read all required data, causing transactions or ledgers to disappear. To fix it, use Tally’s Ctrl + Alt + R (Rewrite) at the company selection screen, or restore from a backup. If that fails, contact Tally Support for data repair. Avoid using or overwriting the damaged data folder before recovery.
Invalid master entries
When Tally Prime shows a File/System error with "Invalid master entries", it means some master records—like ledgers, stock items, or cost centres—are damaged, incomplete, or incorrectly referenced within the data. This usually happens due to abrupt shutdowns, file corruption, or inconsistencies during data entry or syncing. These invalid entries prevent Tally from reading the data properly, which can cause the company to fail to load, or certain features like reports and vouchers to malfunction. Tally stores master records in a very structured way, and any broken link or missing information in those entries can trigger this kind of error. The system error often acts as a safeguard, preventing further damage to data by blocking access until the issue is resolved. In most cases, a data rewrite using Ctrl + Alt + R can clean and repair the master files. If the problem continues, restoring from a backup or getting help from Tally Support to clean the master files manually is necessary. You should avoid modifying or copying the affected data folder without guidance, as that could make recovery harder.
Incorrect or modified transactions
When Tally Prime shows a File/System error related to "Incorrect or Modified Transactions," it means some vouchers or transaction records have become corrupted, partially saved, or altered in a way that breaks their internal structure. This can happen due to system crashes, forced shutdowns, disk errors, or if files were manually tampered with. Tally uses a strict format to store every transaction. If any part of that format is missing or altered—such as a broken date reference, missing ledger, or incorrect amounts—Tally can't process those entries, leading to this error. As a result, you may be unable to open the company, access reports, or post new entries. To fix this, Tally offers a data rewrite utility that tries to clean up and correct these issues automatically. If that doesn’t work, restoring from a backup or getting expert help to repair the data files is often required. It’s important not to overwrite the existing data or try manual edits, as that could cause further loss. Regular backups are the best safeguard against these kinds of errors.
Conclusion
File/System Errors in Tally Prime usually indicate data corruption or structural issues in the company data files. These errors can occur due to improper shutdowns, disk failures, power loss, or file tampering. Common types include: 🔸 Missing or Unreported Data – Indicates partial loss or corruption of transaction or master data, making some records invisible or unreadable. 🔸 Invalid Master Entries – Happens when master records like ledgers or stock items are damaged or improperly linked, causing Tally to block access or crash. 🔸 Incorrect or Modified Transactions – Suggests that some vouchers are altered or broken, leading to calculation errors, incorrect reports, or system-level failures.
