# "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.
