## How to Post Sale Challan Stock on Retrieval Instead of Challan Date in Sale Bill?
In this tutorial, we’ll demonstrate how to use the **"Do Not Post Stock for Sale Challan Documents"** feature in Logic ERP. This option allows you to control **when** and **how** stock is updated, offering more flexibility in your inventory management.
***
### **Access Sale Voucher Configuration**
* Go to **Sale Voucher Configuration**.
* Select the **relevant Sale Challan Series**.
* Locate the option labeled as:
> **"Do Not Post Stock for Sale Challan Documents"**
This feature ensures that **stock is not impacted** at the time of challan creation. It’s ideal when challans are used only for reference or documentation—not for actual stock movement.
***
### **Scenario 1: Feature Disabled**
Let’s first understand the default behavior **when this feature is turned off**.
#### **Step-by-Step Flow:**
* **Disable** the feature in both the **Challan Series** and the **Billing Series**.
* Check the **current stock** of the item in the **Stock Query Report**.
* Example: Current stock = **100 units**
* Create a **Sale Challan** dated **1st July 2025**.
* Save the transaction.
#### **Observation:**
* The **Product-wise Stock and Sale Report** shows:
* Stock **reduced** as of **Challan Date**
* Sale posted as of **Challan Date**
Now retrieve the challan into a **Sale Bill** dated **25th July 2025 and** save the bill.
#### **Result:**
* The stock posting is **reversed** from the **Challan Date**.
* Stock and sale postings are now shifted to the **Bill Date (25th July 2025)**.
***
### **Scenario 2: Feature Enabled**
Now let’s enable the feature and observe the change.
#### **Step-by-Step Flow:**
* **Enable** the option in both the **Challan** and **Billing Series**.
* Confirm the stock of the item is still **100 units**.
* Create a **Sale Challan** dated **1st July 2025**.
* Save the challan.
#### **Observation:**
* In the **Stock Report**, stock remains **unchanged** (still 100 units).
* This means: **No stock is deducted** when the challan is generated.
Now try to **retrieve the challan into a Sale Bill** dated **25th July 2025**.
Before retrieval, go to **Lot Search** to check available stock for billing:
* While the stock report shows **100 units**, the system has **reserved** the challan quantity.
* This prevents double billing and ensures availability is accurate.
#### **Final Observation (Post Billing):**
* Once the challan is retrieved and bill is saved:
* Stock is updated **as of the Bill Date (25th July 2025)**
* Both **Stock** and **Sale entries** are reflected on the **billing date**, not the challan date
***
### **Key Takeaways**
| Mode | Stock Impact on Challan | Stock Impact on Billing |
| -------------------- | ----------------------- | ----------------------------- |
| **Feature Disabled** | Yes (on Challan Date) | Reversed & moved to Bill Date |
| **Feature Enabled** | No (on Challan Date) | Yes (on Bill Date) |
* This feature helps **decouple documentation from inventory movement**.
* Ensures **accurate stock availability** for billing, while allowing challan issuance without immediate stock effect.
