Truncate is a DDL operation, do you have DDL replication enable ? in your OGG environment
Maybe you need a historical table on your target DB, so maybe you can create a Job to copy the Data from the target table to the historical table.
you need to check if you have enable a DDL replication at the source database? if the DDL installed and enabled, you can control which DDL to capture from the extract and replicat by using DDL Include and DDL exclude parameters.
