SAPUI5 - Insert more than 1 record in sap - service gateway

Hi Experts ,

I have one doubt . I created an application in fiori and I try to submit my data in SAP. The problem is I have a list of items and I want to insert this list in one unic request .

Look at the example :

I have a list with 3 items like :

Name Quantity Unit A 1 AU B 2 D C 1 AU

And what I want to do is to put this three items in same request .

How can I send this 3 items for sap using service gateway with method created in same time?

I think the best way is maybe to send the first line and after send one by one doing the update in the last request I created.
I don't know if are available other options.

Can you help me please ?

thanks very much for your time .
Best Regards
