Discount locks help control the usage of **Cash Discount (CD), Trade Discount (TD), Special CD (SPCD), schemes, and billing permissions** for specific customers, ensuring pricing discipline and policy compliance during sales billing.
***
### **Access to Party Wise Discount Locks Setup**
* Navigate to the **Main Menu**

This window allows you to define discount permissions and restrictions for individual customers.
***
### **Review Default Restrictions (No Discounts Allowed)**
* Select a **customer**
* In **Entry Mode**, select the same customer
* Click **Refresh**
**Observation**
* You will notice that:
* **CD, TD, and SPCD** are **not allowed**
* No discount values are permitted for this customer by default
***
### **Verify Restriction in Sales Bill**
* Open the **Sales Bill** window
* Initiate a new transaction for the selected customer
* Try entering **CD, TD, or SPCD**
**Result**
* The entered discount value is **automatically removed**
* The system restricts discount entry due to discount locks
***
### **Enable Allow CD Lock**
* Return to **Party-Wise Discount Locks**
* Enable **Allow CD** for the customer
* Save the changes
**Verify**
* Go back to the **Sales Bill**

***
### **Review Other Discount Lock Options**
The discount lock window also includes advanced controls such as:
* **Lock Scheme (Percentage)**
* **Lock Scheme (Rupees)**
* **Lock Scheme Per Unit**
* **Stop Billing if Last CD Is Not Cleared**
* Select another customer, apply these locks as required, and **save the changes**.
***
### **Verify Scheme Locks in Sales Bill**
* Open the **Sales Bill**
* Initiate a new transaction
* Press **F5** on the item name to define a scheme in rupees
**Result**
* The scheme value is **restricted and not applied**
Similarly:
* When **Scheme Per Unit Lock** is enabled
* Any entered value is **blocked** and does not reflect in the bill
***
### **Apply “Stop Billing if Last CD Is Not Cleared” Lock**
This lock prevents new billing until the previous CD amount is settled.
**Process**
* Apply **CD** in a sales bill
* Save the bill in **Credit Mode**
* Attempt to create a new bill for the same customer
**Result**
* The system displays a message indicating:
> Bill Number: GST-170 of CD 149.9000 is pending
***
### **Clear Pending CD and Resume Billing**
* Open **Cash Received Voucher**
* Enter the receipt against the previous bill
* Adjust and settle the bill
* Save the voucher
**Verification**
* Return to the **Sales Bill**
* Initiate a new transaction for the customer
Billing is now **allowed**, as the previous CD has been cleared.
