Hey! If you’re unable to change the date in Tally ERP 9 (version 6.0.3), it’s usually due to a couple of common reasons. Here are some checks and fixes:
### Possible reasons why you can’t change the date:
1. **Voucher Type Configuration Restriction:** Sometimes, the voucher type might have a **date lock** or restriction enabled.
2. **Period Lock (Accounting Period Lock):** Tally can be set to allow entries only within a certain date range.
3. **User Security Rights:** If you’re logged in as a user with restricted rights, date change might be disabled.
4. **Tally Software Bug or Glitch:** Rare, but can happen especially in older versions.

### How to fix this:
#### 1. Check Accounting Period
* Press **F2 (Period)** on the Gateway of Tally screen. * Set the date range to a broader period covering the date you want to enter. * Try again to change the voucher date.
#### 2. Check Voucher Type Configuration
* Go to **Gateway of Tally > Accounts Info > Voucher Types > Alter** * Select the voucher type you are using (e.g., Sales, Payment) * Check if **"Use Date Lock"** or similar option is enabled; if yes, disable it.
#### 3. Check User Rights
* If you use security control, log in as **Admin** or user with full rights. * Go to **Company > Security Control > User Roles** and see if date change is restricted.
#### 4. Try to Change Date with Shortcut
* In voucher entry screen, press **F2** to change the date. * If F2 doesn’t work, it means the date change is disabled somewhere.

### If nothing works:
* Try restarting Tally or your computer. * Consider updating Tally to the latest version if possible. * Backup your data and reinstall Tally if you suspect a bug.
