Hi Vicky,
Using ODATA service you can only insert one record at a time, hence this will not be of use for your scenario.
As your using XSJS, you can create a procedure which accepts table type as input parameter, inserts all the records passed to this table type into your respective table as logic.
You can call this procedure inside XSJS and pass the captured input values from front end which will serve the purpose.
Regards,
Anil
