# LOT Number as GRN in Purchase Workflow

A new update in Logic ERP introduces the ability to automatically generate LOT numbers based on the GRN number during the purchase process.<br>

This allows for streamlined tracking and inventory management by linking incoming stock directly with its LOT number, ensuring better traceability and compliance throughout the supply chain.

**Step 1:** Navigate to the Purchase Voucher Configuration in Logic ERP\
Click on Other Settings- 1 and then Locate the option Labeled: **LOT Number As:** Select **{GRN No.}**

**Step 2: Implementing the Functionality in Purchase.**<br>

* Navigate to the Purchase module and create a new Purchase Bill.
* Select the desired Item from the list.
* As soon as the item is selected, the system will automatically generate a LOT Number using the "**GRN Number"**, ensuring accurate tracking and traceability.<br>

## 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-version-release-notes/may-2025/purchase/lot-number-as-grn-in-purchase-workflow.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.
