When Field Changes hook

Use this hook to react on a change in a field. You can use and set the values of the form fields.
Note: To have the standard fields available for the hooks ensure you have at least Enterprise Server version 10.5.2 with KB 1923135 applied.

Example:

function extern void currency.when.field.changes()
{
        if currency = "EUR" then
                prnt.sellpr = tcyesno.yes
        else
                prnt.sellpr = tcyesno.no
        endif
        display("prnt.sellpr")
}
