## How to Configure Branch Wise Backdate Entry and Modification Locking Schedule?
In this tutorial, you will learn how to **apply backdate entry and modification restrictions branch-wise** in Logic ERP.\
This feature helps organizations maintain **data consistency and control across multiple branches**.
***
### Open Branch-Wise Locking Setup
**To begin:**
* Navigate to the **User Access Module**.
* Open **Set Branch Wise Back Date Entry / Modification Locking**.
This window displays a **list of all branches** available in the system.
***
### Select Branch for Locking
* Identify the **Branch** where you want to apply restrictions.
* Press the **Spacebar** in the respective column.
* A new window will open showing a **list of documents**.
***
### Choose Document for Locking
* Select the **document** (e.g., *Sale Document*).
**Open Lock Settings:**
* Right-click → Click **Settings**\
**OR**
* Press **F3** (shortcut)
***
### Configure Lock Criteria
* The **Lock for Back Date Entry Window** will open.
* Here, you can define different locking rules.
***
### Apply “Till Date” Lock
Let’s configure a **Till Date Lock**.
* Select the **“Till Date” option**.
* Enter the **specific date** up to which entries should be locked.
* Click **Save**.
**What this means:**
* All transactions **up to the selected date** will be:
* Restricted for new backdated entries
* Restricted for modifications
***
### Implement the Lock (Branch Level)
* Now verify how the restriction works.
* Ensure you are logged into the **same branch** (e.g., Head Office).
#### Implement Backdated Entry Restriction
* Open the **Sale Bill Window**.
* Create a **new transaction** with a date **within the locked period**.
* Try to **save the bill**.
**Result:**
* The system will **block the entry**
* An error message will be displayed
***
### Implement Modification Restriction
* Open an **existing bill** dated before the locked date.
* Attempt to **modify and save** it.
**Result:**
* The system will **prevent modification**
* Changes cannot be saved
***
### Key Benefits of Branch-Wise Locking
* Apply control at **branch level**
* Maintain data consistency across locations
* Prevent unauthorized backdated entries
* Strengthen audit and compliance
* Enable centralized control with decentralized operations
***
### Final Outcome
You have successfully learned how to:
* Configure **Branch-Wise Locking Settings**
* Restrict **Backdated Entries & Modifications**
* Enforce **branch-level data control**
Your system is now better equipped for **multi-branch security and operational discipline**.
