Generally, you can use drilldown in your list projects. You can find some helpful information about drilldown in the programmer’s reference at chapter “Drilldown Reports in Preview”.

im already read combit documentation “Programmer Reference” and im follow it…
my step is im setting the option with LlSetOption(hjob, {&LL_OPTION_DRILLDOWN}, 1) Method to activated that drilldown function.
but i dont understand how to use a callback LL_NTFY_VIEWERDRILLDOWN?
i hope someone can help me with some example for my trouble.
