How to Overwrite Lot Numbers / Batch Numbers and Rates?
In this tutorial, we will learn how to override lot numbers and modify lot-wise item rates in Logic ERP and how to track rate changes using system reports.
Opening the Overwrite Lot Number / Rate Utility
Navigate to the Inventory Module from the main menu
Open Overwrite Lot No.'s/Rates.
Selecting Item and Lot for Modification
Select the required Item Name
Choose the corresponding Lot / Batch Number
Click Refresh to load the current rate details
Understanding Default Rate Behavior in Sales Billing
Before making any changes, let’s review how rates work by default:
Open the Sales Bill window
Transact an item normally
The system applies the existing lot-wise rate by default
Note:
You can manually edit the rate in the sales bill by pressing F5 on the Lot / Batch column.
However, editing each lot individually can be time-consuming.
Overwrite Lot Numbers and Rates Using Utility
To simplify bulk rate changes:
Navigate to Overwrite Lot No.'s/Rates
Enter the new rate against the selected lot
Modify rates item by item as required
The rate defined here will be automatically picked in the sales bill whenever that lot is selected.
Overriding Rates for All Items at Once
Press F3 in the rate column
Enter the new rate
The system will overwrite rates for all listed items
Click Save to apply the changes
Note: If the F3 shortcut is not working, enable the “Overwrite Rate for All Items” option from the Configuration menu at the top.
Verifying Updated Rates in Sales Bill
Return to the Sales Bill window
Create a New Transaction
Select the item and lot
Result:
The updated batch number and overridden rate are automatically applied.
Tracking Lot Rate Change History
To review both old and new rate values:
Go to the Menu Bar
Navigate to Reports/Queries
Click on Item Reports
Open Item Wise Rate Change History Report
Select the required Item(s)
Generate the report
The report clearly displays:
Old Sale Rate
New Sale Rate
Old MRP
Updated MRP
Conclusion
This completes the Override Lot Number and Rate process in Logic ERP, enabling quick and efficient lot-wise rate management along with complete rate change traceability.
