## How to Globally Disable Negative Stock Entry ?

***

### **Enable the Restriction Setting**

* Click to **Save** and Restart the software to apply the changes.

***

### Implement the Functionality

* Open the **Purchase Voucher** window.
* Suppose you already have a purchase entry dated **10th July**.
* Now go to the **Sale Bill** window and create a sales transaction on the **current date** using the same item.

***

### Attempt to Delete the Purchase Entry

* After saving the sales bill, try deleting the purchase entry from **10th July**.
* Since deleting the purchase will result in **negative stock**, the system will display an **error message** and **block** the deletion.

### Important Notes

* Even if **negative stock is allowed in the transaction configuration**, this **global setting overrides** it.
* This ensures **no transaction**—whether manual or system-triggered—can cause stock to fall below zero.
* Applies across **all modules and users** for consistent inventory control.
