### **Apply Across Series and Branches:**

* The same option is also available in **Sale Bill Configuration**.
* However, this setting must be configured **individually for each Series** if done from there.
  * Note: If you want to disable rate modification for a particular series, then lock the rate column using **Column Locks**.
* To apply the restriction **across all series and branches**, it is recommended to use the **Logic Global Admin** settings.

### Validate the Changes

* **Restart the software** to ensure all settings take effect.
* Create a new **sale voucher**.
* Try modifying the rate in the voucher entry.
* The software will now **restrict any manual rate modification**.
