Voucher Numbering
By default, the Voucher Numbering is set to "Automatic" in Tally ERP. i.e. the voucher numbers are assigned by Tally Software irrespective of the Voucher number you may have given in the Excel sheet (for uploading into Tally).
To change the Voucher Number to manual, use the option :
1. Gateway of Tally >> Accounts Info >> Voucher Types
2. Next, select the Voucher type (ex: Sales) and set the "Voucher Numbering" to "Manual".
Now, when you import the Excel data into Tally, the Voucher Numbers are assigned as per the values given in the Excel sheet.
Unique ID
A Unique ID is to be given for each voucher in the udi-Magic Standard template. You may use the same value for Voucher-Number and Unique ID, but ensure that the Unique ID value is always unique for each Voucher.
