# Allow Change of Party Name in Bills created from Challans

**YouTube:** [How to Allow Party Name Change in Sale Bills Generated from Sale Challans ?](https://www.youtube.com/watch?v=GeTKmVye-ew)

In this tutorial, we’ll guide you on how to enable the option to **change the party name in sale bills** that are created from a **Sale Challan** in Logic ERP.

***

### Understanding the Default Behavior

By default, Logic ERP does **not allow** changing the customer (party) name once a **Challan is retrieved** into the Sale Bill. Let’s take a quick look:

1. Open the **Sale Bill window**.
2. Retrieve a **Sale Challan** into the bill.
3. Now try changing the **Customer Name**.

You'll receive an error message:

> *"Party cannot be changed as the bill is created from a Challan."*

### Enabling Party Name Modification

To allow editing of the customer name in such cases, follow these steps:

**1. Open Logic Admin Tool**

* Navigate to the **Logic ERP installation folder**.
* Locate the application named **Logic Admin**.
