Understanding Nested Object Templates and Field mapping

The Nested Object Template- Nested objects refer to a data structure where an object is encapsulated within another object. In simpler terms, think of a nested object as a container within a container. It enables the grouping of related data, creating a logical relationship between the outer and the inner objects. The ‘IsMarker’ Column in the templates incorporated in Data Loader identifies the scenario when a new object has to be created. 

For example, When referring to the Standalone Invoices template, the presence of a new object within the outer object is indicated by the properties ‘IsNewInvoiceItem’ and ‘IsNewCustomRates’. It is mandatory for data accuracy to map the ‘IsMarker’ Column in the Field Mapping Interface.
