Adding new detail Records on Update

[Adrian Mercieca]

Hi,

I have a master/detail relationship between 2 queries in a datasnap
application.

Is it possible to insert new records into the detail when a new record
has been inserted into the master, before the whole data is committed to
the DB? I'd like to be able to do this on the server side.

I know that I should be doing this on the OnUpdateData or
OnBeforeUpdateRecord of the export dataset provider on the server, but
what is the exact syntax to use? When I tried adding new records to the
detail data packet, I kept getting an 'operation not supported'
exception of some sort.

Tks - Adrian.
