# Do Not Save C.F With Lots

## How to Avoid Multiple Lot / batch creation for different Conversion factors in Purchase?

 In this tutorial, we will explore a feature that prevents saving the conversion factor (CF) with the lot number in a purchase voucher.

### **Scenario Before Enabling the Feature:**

* Create a Purchase Voucher without enabling the specified option.
* Add items with predefined unit conversions from the master data.
* Enter the same item twice:
  * First entry: 24 units per box.
  * Second entry: 48 units per box.
* Save the voucher.
* Reopen the saved entry and press **F5** in the **Pack’s column**:
  * The software saves different conversion factors (24 and 48 units per case), creating two unique lot codes.

### **Enabling the Feature:**

* Navigate to the "**Purchase Voucher Configuration".**
* Locate the option and enable **"Do Not Save CF with Lot"** to prevent saving conversion factors with lot numbers.

### **Scenario After Enabling the Feature:**

* Create a new purchase entry with different MRPs.
* Enter the same item twice with different conversion factors:
  * First entry: 24 units per case.
  * Second entry: 48 units per case.
* Save the voucher.
* Modify and review the saved entry:
  * No new lot is created.
  * The conversion factors are not saved with the lot.

<figure><img src="/files/5DYymGN1fDLtorqjlEB5" alt=""><figcaption><p>Now, you can see that the LOT remains the same, and no new conversion factor has been created.</p></figcaption></figure>

🔹 **Conclusion**

* This feature ensures consistency in lot management by preventing different conversion factors for the same lot.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://kb.logicerp.com/logic-erp-learning-hub-tutorials-and-best-practices/setups/configurations/purchase-voucher-configurations/other-settings-1/do-not-save-c.f-with-lots.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
