When creating accounts via an opportunity in the Aria for Salesforce user interface, you can set an Aria Functional Account Group. This field is the functional account group number specifically designated for statement sequence number assignment. This parameter is configured when creating an account under the Aria Account Functional Group drop-down or revised after an account has been committed to Aria.
You can sync sequence groups from Aria to Aria for Salesforce during client plan sync and add/view/edit the sequence groups on accounts in Aria for Salesforce. When an account is created, this value is passed to Aria during commit. In an existing account, the user can view the sequence group and update it.
This functionality ensures that statement numbers are generated correctly even for statements/invoices generated directly by the creation of the account.
