CAUSE:

There are additional notes required by Replication.

Each record created/updated/deleted is performed within a logical operation. A logical operation is a unit of work within a transaction that insures that a record and it's index entries are updated as a unit. The additional notes being seen describe the beginning and end of the logical operations.

The Replication Agent uses these to perform low-level record-get locks. Record-get locks prevent half updated records from being retrieved by 4GL or SQL.

FIX:

This is an expected behavior as per explanation given in cause.
