## How to Configure Lot or Batch Selection in Sale Bill ?

Logic ERP offers a smart feature that allows you to **automate lot or batch selection during billing**, making your processes **faster**, **smoother**, and **error-free**. This tutorial explains how each configuration parameter works.

***

### **Access Lot Selection Settings**

* Navigate to **Sales Voucher Configuration**.
* Select the **relevant billing series**.
* Locate the setting labeled **"Lot Selection"**.
* You will find **six parameters** to configure automatic lot selection. Let’s explore them.

***

### **Manual Lot Selection**

* **Functionality**: Requires users to **manually select a lot** during transactions.

* **Best For**: Businesses needing precise control over lot tracking for each item.

***

### **Auto Pick First Lot (Sale Items Only)**

* **Functionality**:
  * Automatically picks the **first available lot** for **sales transactions**.
  * For **sale returns**, it opens a **Lot search window**, allowing **manual selection**.
* **Mechanism**: Works on **FIFO** (First-In First-Out) method.

**Example**:

* During **Sales**: System auto-selects the first lot.
* During **Returns**: User must manually choose the correct lot.

***

### **Auto Pick If Single Lot**

* **Functionality**: If an item has **only one lot**, the system **automatically picks it**.
* **Ideal For**: Simplifying transactions with limited lot availability.

***

### **Auto Pick First Lot (All Items)**

* **Functionality**:
  * Automatically selects the **first available lot** for both **sales** and **sale returns**.
* **Effect**:
  * Streamlines lot selection in **both directions** of inventory movement.

***

### **Auto Pick First Lot, Skip Stock Items**

* **Functionality**:
  * Automatically selects the lot for items marked **“Do Not Affect Stock”** in Item Master.

* For **normal stock items**, the **lot search window** appears for manual selection.

**Example**:

* Item marked **"Do Not Affect Stock"** → **Auto selection**.
* Normal item → **Manual lot selection** window appears.

***

### **Auto Pick If Single Lot or Same MRP**

* **Functionality**:
  * Automatically selects the lot if there is either:
    * **Only one lot available**
    * **Multiple lots with the same MRP**.
* **During Sale Return**:
  * If only one lot is available → **Manual selection window** still appears.
  * If multiple lots have the same MRP → **System auto-picks the first lot**.

**Example**:

* Item with single lot → Auto-picked.
* Multiple lots, same MRP → Auto-picked.
* Sale return with one lot → Requires **manual confirmation**.

***

### Final Step: Save the Bill

* After completing item entries and lot selections, **save the bill**.
* The selected configuration will dictate how the lot selection behaves for **both sales and returns**.

***

### **Benefits of Automated Lot Selection**

* **Reduces manual errors** in lot selection.
* **Speeds up the billing process** significantly.
* Ensures **consistency in inventory handling** using FIFO and MRP-based logic.
