**Understanding TDS and Purchase Voucher Management in Logic ERP**

In this tutorial, we'll explore a feature that restricts saving purchase vouchers when TDS (Tax Deducted at Source) details are required for a specific party. Follow these steps to configure your system:

### Step-By-Step Guide:

#### Activating the Feature

* Navigate to the "Purchase Voucher Configuration".
* Locate the option "Do Not Allow Entry W/O TDS (If exists)".
*  Tick the checkbox to activate this validation.

### **Demonstration: Creating a New Purchase Bill :**

* Create a "Purchase Bill".
* As soon as you attempt to **save the purchase bill** after entering the item and its details, the software will prompt the message:\
  \&#xNAN;**"TDS Details Found for this Party. Cannot allow entry without TDS."**
