The post-installation script creates a default set of numbering series, and it is ready for use.
Update Numbering Series
Open the App Launcher. Search for Numbering Series.
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.
