* Ensure that your entry has been saved. For example, we have entered an amount of 25,000.

### **Validating During Purchase Challan:**

* Create a **New Purchase Challan**.
* Enter details: **Challan Number, Date, GPN Number, and GPN Date**.
* Attempt to **save the challan**:
  * If the **Challan Amount** does not match the **GPN Entry**, a validation message appears.
  * The software **prevents saving** the voucher until the amounts match.

**Finalizing the Entry**

* Adjust the **Challan Amount** to match the **GPN Entry**.
* Save the **Challan** again.
* The software **validates the Bill Number** against the GPN Entry.
* After corrections, the software **allows the entry to be saved**.
