## How to Allow a Zero Sale Rate entry in Purchase?

In this tutorial, we’ll explore a setting in Logic ERP that allows skipping or leaving the sale rate blank during transactions, providing more flexibility by bypassing the default prompt to enter a sale rate.

### **Creating a Voucher Before Applying the Setting**

* Let's start by creating a **purchase voucher** without enabling the setting.
* We will transact an item and attempt to **leave the Sale rate as zero**.
* As seen here, the **software generates a message** prompting us to enter the sale rate.
* The transaction **cannot be completed** until a sale rate is defined.

### **Enabling the Option to Skip Sale Rate**

1. Go to **Purchase Voucher Configuration**.
2. Click on **Other Settings 1**.
3. Scroll down and **tick the option** labeled **"Allow Sale Rate is Equal to Zero"**.
4. Click on **Save** to apply the changes.

### **Testing the Setting in a New Transaction**

* Now, let’s try transacting another **purchase entry** with the setting enabled.
* This time, when we **leave the sale rate blank**, the software **does not prompt any message** and allows the transaction to proceed smoothly.
