How to Restrict Modification of Retrieved Sale Challans?

In this tutorial, we will learn how to restrict the modification of a retrieved Sale Challan in Logic ERP. This setting ensures data consistency by preventing edits to challans already used in billing.

---

Access Sale Voucher Configuration

• Navigate to Sale Voucher Configuration in Logic ERP.

• Select the relevant Challan Series for which you want to enable this feature.

• Locate the option labeled as: “Do not allow Modification of Retrieved Challan”

• Keep this feature disabled initially to observe the default behavior.

---

Implement Feature as Disabled

• Create and save a Sale Challan.

• Open the Sale Bill window.

• Use the Retrieve Challan option and select the item to retrieve into the bill.

• Save the Sale Bill.

Now go back to the Sale Challan window.

• Attempt to modify the same challan (e.g., change the quantity).

• Save the challan.

Since the restriction was disabled, the system allows modifications even after the challan has been retrieved in the bill.

Implement Feature as Enabled

• Return to Sale Voucher Configuration.

• Enable the option:

  "Do not allow modification of Retrieve Challan"

• Save the settings and restart the software if needed.

• Again, try to modify the same Sale Challan that was retrieved in the bill.

• Change the quantity and attempt to save.

This time, the system will prevent the modification and show an error message:

"This Challan has already been retrieved in a Sale Bill. Modification is not allowed."
