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."
