Autonumber groups allow users to use unique counters for document numbering masks in various document types. For example, when an autonumber group is set up for contracts, if a new contract is created and the number is entered manually, and the number is CONTRACT-@-#, the @ will be replaced by the fiscal year and the # will be replaced by the next number in the sequence. In this example, the first contract created with this specific numbering system would be called CONTRACT-19-0001.
Autonumber groups can be set up in System Setup | Autonumbering | Groups. Only one group at a time can be set up for a specific document type.
