Selective Modification Timestamp

Demo file: (requires FM 8 or later)

Have you ever wished for a modification timestamp that would only update if a user manually edited a field? In other words, a timestamp that would not update based on scripted actions, or non-field-based activity like creating, duplicating or importing records? This can be achieved in a variety of ways, but the technique here uses a simple auto-enter calc, which I was introduced to by Nick Orr at Goya Pty Ltd.

Define a timestamp field, ts_mod_selective, with this auto-enter syntax:

Let ( [
trigger = GetField ( "" ) ; // note the innovative use of GetField
ros = Get ( RecordOpenState ) ;
ies = IsEmpty ( Get ( ScriptName ) ) ;
ts = Get ( CurrentHostTimeStamp )
] ;
Case (
ros = 1 ; "" ;
ros = 2 and ies = 1 ; ts ;
ts_mod_selective // for FM 9 or later, we could use Self
// instead of specifying the field name
) // end let

Note: if you just want the date or time component, you can enclose all of the above in GetAsDate() or GetAsTime(). And of course, this technique can easily be adapted to work with modification account name as well.
