## How to Set item wise defaults like discounts and Schemes for Purchase?
In this tutorial, we will learn how to **define item-wise defaults for purchase transactions in Logic ERP**. Item-wise purchase defaults help automate discounts, schemes, and other values during purchase entry, ensuring consistency, accuracy, and faster data entry.
***
### **Access to Item-Wise Purchase Defaults Setup**
* Navigate to the **Main Menu**
* Open the **Setup Module**
* Click on **Set Other Item Details**
* Select **Set Item-Wise Defaults (Purchase)** to open the configuration window
***
### **Select Entry Mode and Items**
* You will see two entry modes:
* **Single Entry**
* **Multiple Entry**
* Select **Multiple Entry**
* Click on **Select Items**
* Choose the items for which you want to define purchase defaults
* Use filters such as **Brand Group** or **HSN** to locate items easily
***
### **Define Purchase Default Values**
* Multiple default fields are available, such as:
* **CD (Cash Discount)**
* **TD (Trade Discount)**
* **SPCD**, and others
* In this example:
* Enter **TD = 12%** for the selected items
* Save the changes
***
### **Verify Defined Defaults**
* Open the **Single-Entry** window
* Click on **Refresh**
* You will now see the defined **12% TD** reflected for the selected items
***
### **Check Defaults During Purchase Entry**
* Open the **Purchase Voucher** window
* Create a new purchase entry
* Enter an item for which the default was defined
* You will notice that the **12% trade discount is applied automatically**
***
### **Step 6: Removing Item-Wise Defaults**
* Simply entering **0** and saving will **not remove** the existing default
* To correctly remove a default:
* Set the value to **0**
* Enable the **Save Zero Values** option
* Save the changes
* Open the **Single-Entry** window and click **Refresh**
* The value will now appear as **0**, confirming the default has been successfully removed.
***
### **Using Per-Unit Purchase Defaults (Scheme Per Unit)**
Apart from percentage-based defaults, Logic ERP also supports **per-unit based defaults**.
#### **Example: Scheme Per Unit**
* Define **Scheme Value = ₹5 per unit**
* Use the **Scheme CF (Conversion Factor)** field
* Select the appropriate unit conversion from the dropdown
* Save the configuration
***
### **Verify Per-Unit Scheme in Purchase Voucher**
* Initiate a new purchase entry
* Enter the configured item:
* For **1 unit**, the scheme value will be **₹5**
* Check this under **View Totals**
* Change the quantity to **10 units**
* The scheme amount will automatically update to **₹50**, confirming correct per-unit calculation
***
### **Conclusion**
By defining **item-wise purchase defaults in Logic ERP**, you can significantly streamline purchase entries, reduce manual effort, and ensure consistent discount and scheme application. Whether percentage-based or per-unit based, these defaults enhance accuracy and efficiency across procurement operations.
