In this tutorial, we will walk you through a feature in **Logic ERP** that **restricts manual credit amount entry** during billing, ensuring better control and accuracy in payment processing.

***
### Access Global Settings in Logic Admin

* Navigate to **Global Settings**.
* Under **POS Options**, go to the **POS Options 1** section.
* Locate and enable the option labeled as:
> **"Do not allow Manual Credit Entry in Billing"**
* Click **Save** and **restart the software** to apply the changes.
***
### Implement the Feature
* Open the **Sale Bill – Touch Screen** window and create a new transaction.
* Proceed to the **Multi-Pay Details** screen.
* You will observe that the **credit amount field is now disabled**, preventing any manual entry.
