# "Do Not Allow Purchase Return w/o Purchase Return Challan" Option updated
Logic ERP has introduced a new update to enhance and streamline **Purchase Return control**.
Previously, the option **“Do not allow entry without PO/Challan”** was not enforced correctly for **Purchase Return transactions**, allowing users to create returns without linking a **Purchase Challan Return**. With this update, the system now correctly **restricts Purchase Return entries unless a valid Purchase Challan Return is selected**. This ensures better process compliance, prevents incorrect return entries, and improves overall accuracy in purchase return management.
***
### Step 1: Configurate and Implement in **Purchase Return**
* First, open the **Purchase Return Configuration**.
* In the configuration screen, **enable the option “Do Not Allow Entry Without Purchase Order/Challan.”**
* Once this option is enabled, the system will **not allow you to create a Purchase Return** unless a **Purchase Return Challan is retrieved**.
* This ensures that all Purchase Return entries are **properly linked to the original challan**, improving control and accuracy.

## 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/january-2026/purchase/do-not-allow-purchase-return-w-o-purchase-return-challan-option-updated.md?ask=&goal=
```
`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.
