User-defined scripting allows customer specific business rules and validations to be assigned to a specific table or column level events. These scripts can be invoked automatically, without user interaction.
Note The Allow External Access check box in Company Maintenance must be selected to enable user-defined scripting. This can be used when developing debugging scripts to restrict scripting to a specific test company.
The following table illustrates the events.
Table Events
Execution Description
Script Initialization
When scripting is first initialized for a business object
Set Defaults
When defaults are set for a new record
Pre-Write
Before a record is written with the ability to prevent the write
Post-Write
After a record is written
Pre-Delete
Before a record is deleted with the ability to prevent the delete
Post-Delete
After a record is deleted
Post-Read
After a record is read
Pre-Totals
Before totals are calculated (only on line detail tables)
Column Events
Pre-Validation
Before a column value is validated (after dictionary validation, but before MAS and Master Developer validations)
Post-Validation
After a column value is validated
Note Pre-events (except for Pre-Totals) can return a failure message and interrupt further processing. Because these validations are enforced in the business object, these messages are displayed in the MAS data entry tasks, and also logged if invoked externally using Visual Integrator or the object interface.
