You can define this script step to use any calculation expression to determine the next serial value of a field that has been defined as an auto-entry serial number field. The calculation always evaluates to a text result.
For example, you might want to reset the next serial value after you do one of the following:
Example 1 
Calculates the number of the next available invoice ID, using the Max function to return the highest value in the Invoice ID field. If an invoice ID contains non-numeric data, then the calculation would need to be more sophisticated to maintain the numeric and non-numeric data.
Go to Record/Request/Page [Last]
Set Next Serial Value [Invoices::Invoice ID; Max ( Invoices::Invoice ID ) + 1]
Example 2 
Sets the next serial number value in the Invoice ID field options after importing records. Useful if Perform auto-enter options while importing is not selected in order to preserve dates and other auto-entered values.
Import Records [Add; Mac Roman]
Set Next Serial Value [Invoices::Invoice ID; Get ( TotalRecordCount ) + 1]
Example 3 
Prompts the user to input the next serial value.
Show Custom Dialog ["Set the next serial number value"; Invoices::Next Serial Value]
If [Get ( LastMessageChoice ) = 1]
Set Next Serial Value [Invoices::Invoice ID; Invoices::Next Serial Value]
End If
