Can I access the trace files of errors (for experts and on-premises deployment only)?

If needed, you can access ServiceNow trace files of errors by Opening the trace file from the HOPEX Server Supervisor tool and clicking the line related to ServiceNow trace files.

Note that you cannot check synced objects in the trace files.

How can I avoid duplications?

To avoid duplicated data, it is possible to define which attribute to use as a unique identifier when defining a mapping.

See Setting Up a Unique Identifier.

How is data integrated within each system?

 

Data integration depends on each mapping configuration, and more specifically the direction of data transfer and the synchronization mode (whether objects should be preserved or deleted from the target system).

See Mapping Tables and Deleting or preserving objects from the target system - Examples.
