How to load odata json with $expand parameter and bind deep entity data to list control in master page?

Hi expert,

How to load odata json with $expand parameter and bind deep entity data to list control in master page?

With TCode:/IWFND/GW_CLIENT,I can use url "/sap/opu/odata/SAP/ZWPURCHASE_REQUEST_SRV/HeaderSet?$expand=TextLines,Items/ServiceLines,Items/Accounts,Items/AddrDeliverys,Items/TextLines&$format=json" to get the json data,

But I don't know how to get json data and bind deep entity json data to list control in master page in fiori app.

thank you.

best regards,

felix.
