I have posted a sample app as QC 43284

In a standard M/D/D datasnap application, deleteing a sundetailed detail
record may cause $4005 (Mismatch in DataPacket) after ApplyUpdates.
This happens in Reconcile mechanism if the following condition exists:

1. Insert a pair of detail-subdetail records which raises error in database
(say PK violation)
2. Insert another pair of detail-subdetail records
3. Delete the last inserted detail (we assume cascading relationship)
4. ApplyUpdates.

The PK error raises and then a "Mismatch in DataPacket"
