Manage Duplicate Numbers for GST Vouchers in TallyPrime

Transactions in a financial year that have duplicate Voucher Nos. or Document Nos. appear under Uncertain Transactions (Correction Needed) in reports like GSTR-1, GSTR-3B, GSTR-2A, GSTR-1 Reconciliation, GSTR-2B Reconciliation, Annual Computation, e-Invoice, and e-Way Bill.

In TallyPrime 7.0 and later, you can easily view and correct duplicate voucher numbers and continue with GST return filing. You can also configure voucher types to use prefixes and suffixes for unique numbering and update numbers of existing vouchers accordingly.

You can choose any one of the above-mentioned GST reports and correct voucher numbers for all your duplicate vouchers.
