## How to make MRP entry in Purchase mandatory in Logic ERP Software?

In this Tutorial, we will discuss a crucial validation option that enhances data integrity by ensuring the MRP (Maximum Retail Price) entry is never missed.

To maintain accuracy and integrity in your ERP system, it's essential to ensure the MRP entry is neither left blank nor set to zero. This feature prevents incomplete data entries that could lead to downstream errors.

#### How to Enable MRP Validation

1. Navigate to the "Purchase Voucher Configuration".
2. Select the option "Do Not Allow Zero MRP".
3. Tick the checkbox to activate this validation.

### **Observe Effect on Purchase :**

* Create a "Purchase Voucher".
* Now, whenever you make a purchase and accidentally leave the MRP at zero, the software will display a prompt "MRP Entry is Mandatory".

With this setting enabled, any attempt to save an entry with a blank or zero MRP will be restricted, enforcing data completeness.
