## How to Prevent Loyalty Point Updates When Modifying Sales Bills?
In this tutorial, we will learn how to prevent loyalty points from being recalculated or updated when a Sales Bill is modified in Logic ERP.
***
### Objective of This Feature
* Prevent loyalty points from being recalculated after bill modification.
* Preserve the loyalty points originally awarded for a bill.
* Maintain consistency in customer loyalty balances.
* Prevent unintended changes to previously earned points.
***
### Access to the Set Customer Points Configuration
* Go to the **Set Customer Points Configuration** module.
* Locate the option:
> **"Do Not Update Points in Modify Case"**
When enabled, this option prevents the system from recalculating loyalty points when an already saved bill is modified.
***
### Observe the Default Behavior
Let's first observe the functionality when the option is **disabled**.
For this demonstration, the loyalty point settings have already been configured as follows:
* **₹100 spent = 1 Loyalty Point**
* **1 Loyalty Point = ₹1**
Now, navigate to the **Sales Bill** module.
***
### Create a Loyalty Customer and Sales Bill
* Create a new Loyalty Customer.
* Generate a Sales Bill for the customer.
* Enter the required items and save the bill.
* After saving the bill, create a new Sales Bill and search for the same customer to verify the loyalty points.
**Result**
The customer has earned **40 Loyalty Points** based on the configured earning criteria.
#### Modify the Sales Bill
Now, open the same Sales Bill in **Modify Mode**.
* Increase the item quantity.
* This increases the overall bill value.
* Save the modified bill.
* Now, create another Sales Bill and search for the same customer to check the updated loyalty points.
**Result**
Since the **Do Not Update Points in Modify Case** option is disabled, the system recalculates the loyalty points.
The customer's loyalty points increase from **40 to 80 points**.
***
### **Now, let's observe the behavior after enabling the feature.**
* Now, return to the **Set Customer Points Configuration** module.
* Enable: **"Do Not Update Points in Modify Case"**
* Save the configuration.
***
### Create a New Sales Bill
* Create a new Loyalty Customer.
* Generate a Sales Bill.
* Save the bill.
* Create another Sales Bill and search for the same customer.
**Result**
The customer has earned **40 Loyalty Points** based on the configured earning criteria.
#### Modify the Sales Bill
Now, open the same Sales Bill in **Modify Mode**.
* Increase the item quantity.
* Save the modified bill.
* Search for the same customer again to verify the loyalty points.
**Result**
Although the Sales Bill has been modified, the customer's loyalty points remain unchanged at **40 points**.
The system does not recalculate or update the points awarded for the original bill.
***
### Key Benefits
* Prevents unintended loyalty point changes.
* Maintains accurate customer point balances.
* Protects previously awarded loyalty points.
* Provides better control over loyalty program calculations.
* Ensures consistent point management after bill modifications.
***
### Final Outcome
Once **"Do Not Update Points in Modify Case"** is enabled, Logic ERP preserves the loyalty points originally awarded for a Sales Bill. Even if the bill value or quantity is modified later, the customer's previously earned loyalty points remain unchanged.
