### Parameter Options and Their Functionality

#### **Default**

* This uses the **default sales conversion factor** defined in the **Item Master**.
* **How to Set**:
  * Navigate to Setup\Setup Items and then click on **"Setup Items Multiple Packs/Sizes".**
  * Select the item in which you want to define C.F
  * Define multiple conversion levels (e.g., Tablet, Strip, Case).
  * Set one as the default (e.g., **1 Strip = 10 Tablets**).

#### 🔹 **2. Default CF for Quantity as per Unit**

* Allows you to define a quantity **per unit** during billing.
* **How it works**:
  * For example, if **1 Pack = 5 Tablets**, the rate will auto-adjust accordingly.
  * The **Unit per Pack** column will reflect this, and pricing is divided based on quantity.

***

#### **Item CF 1**

* Picks the **first conversion factor** defined in the Item Master.
* **Example**:
  * 1 Case = 10 Strips
  * 1 Strip = 10 Tablets
  * Therefore, 1 Case = 100 Tablets
* **To verify:** Press **F5** on the **Packs** column during billing to see the applied CF.

***

#### **Item CF 2**

* Uses the **second conversion factor** from the Item Master.
* **Example**:
  * If Item CF 2 = 1 Strip = 10 Tablets
  * The system applies this directly in the sale bill.
* **Units per Pack** will display accordingly.

#### **Item CF 3** (If defined)

* If a **third conversion level** is set in the Item Master, it functions the same way.
* Enables even more granular control for items with multiple packaging levels.

***

### Key Benefits

* **Ensures accurate quantity tracking** across multiple packaging units.
* **Reduces manual entry errors** during billing.
* **Saves time** by auto-selecting appropriate conversion levels.
* **Improves billing precision** for multi-packaged items (e.g., tablets, strips, boxes).
