I have an empty SAPUI5 SmartTable (for Sales Order Items) and there i want to add new single (virtual) row where the user can input some Sales Order Item data, f.e. Material No., Price, Quantity …

My problem now is the following:
This new row should not automatically be processed from the backend. For my understanding the (c)
would be the correct approach to do that.
Am i right?

My Odata Service is V2 and we are on SAP UI Version 1.71.58. Within this version the ODataListBinding#create function is not released.
Am i also right here?

I’ve tried to solve my problem via the ODataModel#createEntry function, but this isn’t working for tables. Is this also correct?
The ODataModel#createEntry is working fine for my header data Smart Field.

What can i do in this case?
What would be the best way to solve my problem?

Further Information:
I need the SmartTable and the OData Model for some automatic search help dialogs via annotations.
