Reltio uses the incremental load method for loading records from the source file to the NPI data tenant.

The incremental load method reads only those records that are not already read and loaded into the NPI data tenant since the last load. The column Last_Update_Date specified in the NPI source file helps to achieve the Incremental load method.

The NPI data tenant retrieves the source file from the 10th day of the previous month and publishes the file on the 17th day of every month.
