This scenario shows how this condition can occur.
However, it is also not included in the second DCM transfer package because it is older than the last generate time.
When a DCM generate is performed, DCM subtracts a small time value from the current time (by default, 60 seconds) to use as the generate time. This operation allows for a time difference of 60 seconds between machines accessing the same database. An object that is modified or becomes a direct or indirect member of a transfer set within 60 seconds of the start of a DCM generate can be included in that DCM transfer package and in the next one.
The synchronization process varies from one installation to another. For specific information about this operation, contact your system administrator.
