The last run is updating but there is no replication performed

This problem occurs with keytable replication, and typically happens when either no data has changed, or the changes are not resulting in keytable entries.

To solve this problem

If DPFill procedures are being used to update the KeyTable, then ensure that direct Microsoft SQL commands are not being used to insert, update, or delete rows. When DPFill procedures are in use, all changes to a table must go through a procedure that calls DPFill_<table>_.
