      {
         "ContactEmployees" : [

CONSOLE ERRORS

Failed to drill-down into ('BUSINESSPARTNERS CODES')/ContactEmployees/Name, invalid segment: Name - /******/BusinessPartners?$select=ContactEmployees,CardCode&$orderby=CardCode sap.ui.model.odata.v4.lib._Cache

If I change {ContactEmployees/Name} to {ContactEmployees/0/Name} they are shown but only 1 single contact, and I need to bring them all

Answer 1

Use the expand option in order to get the ContactEmployees of each BusinessPartners. try this :

 <Table id="idPartnerTable"
                    growing="true"
                    growingScrollToLoad="true"
                    inset="false"
                    items="{
                        path: '/BusinessPartners',
                        parameters:{
                        expand:'ContactEmployees'
                        },
                        sorter: {
                            path: 'CardCode'
                        }
                    }">
