***
### Open Purchase Defaults Setup
To begin:
* Go to the **Setup Module** from the menu bar.
* Navigate to **Party Wise Settings**.
* Open **Branch + Item Group Wise Defaults – Purchase**.
* This window allows you to define **default purchase settings for specific branches and item groups**.
***
### Select Branch & Item Group
* Select the **Branch**.
* Choose the **Item Group Number** from the dropdown.
* Select the relevant **Item Group**.
Defaults will be applied based on this **Branch + Item Group Combination**.
***
### Configure Discounts & Charges
You can define multiple default settings:
**Discount Options:**
* **CD (Cash Discount)**
* **TD (Trade Discount)**
* **Special CD**
**Additional Options:**
* **Labor Charges**
* **Adjustment Amount**
* Define:
* **Per Unit Basis**
OR
* **Using Conversion Factors**
**Rate Adjustment Option:**
* **Add % in Rate**
* Adds a specified percentage to the item rate automatically
***
### Understand CD Type Options
* Let’s configure **CD = 10%**.
**You will see two important options:**
#### **Option 1: Ignore Zero**
* The defined discount (**10% CD**) will:
* Automatically apply in purchase bills
* Based on defined criteria
**Verify Discount in Purchase Entry**
* Go to **Purchase Voucher Window**.
* Create a **New Entry**.
* Enter an item from the selected **Item Group** (e.g., Shirts).
**Result: 10% CD is automatically applied** in the bill.
#### Option 2 Use Zero”
* Now let’s understand the **Use Zero** option.
* Go back to the **"Branch + Item Group Wise Defaults – Purchase"** option.
* Open the **Entry Mode**.
* From the filter at the top, select the configuration that we defined earlier.
* Here, you will find the option **"Ignore Zero"**.
* Change this setting from **"Ignore Zero"** to **"Use Zero"**.
**Configuration:**
* Set **CD = 0**
* Select **CD Type = Use Zero**
**What “Use Zero” Means:**
* No discount will be applied
* Overrides all higher-level discounts
Even if discounts are defined at:
* Branch + Party Level
* Party + Company Level
They will **NOT be applied**
***
### Implement Overwrite Behavior
* Go to **Party + Company Wise Defaults**.
* Define a discount (e.g., 10% CD).
* Save the settings.
***
### Verify in Purchase Bill
* Create a new **Purchase Entry**.
**Result:**
* No discount is applied
* “Use Zero” setting overrides all other configurations
***
### Key Benefits of Branch + Item Group Defaults
