## How to Configure a Combo Scheme on Value/Quantity basis in Sale Bill?
This tutorial explains how to create and apply a combo scheme in Logic ERP, where customers receive a special rate when purchasing a defined set of items together (e.g., Shirt + Trouser).
***
### **Access to Scheme Campaign**
* Navigate to **Configuration Menu → Setup Scheme Campaign**.
* Click **Refresh**.
* Enter the **Scheme Campaign Name**.
* Define the **Active Date Range** for the scheme.
* Click **Save**.
***
### **Define Group Options**
* Open the **Group Options** tab.
* Select your **Scheme Campaign**.
* Create the required groups:
* **Shirts** – Set **Group Type: Item Group**
* **Trousers** – Set **Group Type: Item Group**
* **Formal Set** – Set **Group Type: Combo**
* Click **Save**.
***
### **Assign Item Categories**
* Go to the **Scheme Group** tab.
* Assign the appropriate **Item Categories** to each item group (Shirts and Trousers).
* Save the changes.
***
### **Configure Combo Details**
* Open the **Scheme Combo Details** tab.
* Select each group and define required quantities:
* **Shirts → Quantity: 1**
* **Trousers → Quantity: 1**
* Click **Save**.
***
### **Set Scheme Slab Details**
* Go to **Scheme Campaign Slab Details** from the menu bar.
* Select the same **Scheme Campaign**.
* In **Campaign Group**, choose **Formal Set**.
* Configure:
* **Minimum Quantity:** 1
* **Scheme Basis:** Quantity
* **Slab Value:** 1
* **New Rate:** 999
* Save the configuration.
**Meaning:**
* Individual Shirt/Trouser prices remain higher.
* Buying both together applies the combo price of **₹999** automatically.
***
### **Implement Scheme in Sale Bill**
* Start a **new sale transaction**.
* Add **Shirt** and **Trouser** items to the bill.
* Save the voucher and **tick to apply the scheme**.
* The bill will automatically adjust to the combo price, and the discount difference will appear in the **discount column**.

### **Conclusion**
By following these steps, you can successfully configure a combo scheme in Logic ERP based on quantity or value. This setup enables special pricing when customers purchase a predefined combination of items, ensuring accurate billing and improved promotional management directly through the system.
