Tally IMP Error - Message: Line 117: Can't alter units for 'Item name'!
Solution:
As per the error you are trying to alter unit of measurement of items but the item already have few invoices created with old UOM and its not allowing you to change.
Please open your excel and check if UOM (unit of measurement ) is same as what you have defined in Tally.
For existing item the UoM should be same as what you have already defined in Tally ERP or Prime.
If you still have this issue, Please send us email or create ticket with error details and excel file.
