Not changing the Prefix and Separators is recommended for optimized transaction identification. You can update the Last Number Used for particular transactions, such as Sales Orders, Purchase Orders, or Sales Invoices to continue the last numbers used in the previous ERP system.
It is recommended to use the same 7 digits numbering series for all transactions for consistency.
