Description 
Allows you to use the Manage Scripts feature to update the value. 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:
 •
import records into a FileMaker Pro database with an auto-entry serial number field
 •
delete multiple serialized numbers from a FileMaker Pro database
Notes
 •
This script step affects the definition of the field you specify instead of the actual contents of the field that you specify.
 •
This script step can operate on multiple files. If you specify a field in another file, then FileMaker Pro attempts to update the serial number for the specified field in the other file. To specify a field in another file, define a relationship to that file and use Specify target field to select a field from that file.
Examples 
The following example calculates the number of the next available invoice ID. If the 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 [Table1::Invoice ID; Table1::InvoiceID + 1]
