Delete Batch operation - SAP UI5

Question

Can anyone please let me know the syntax for the DELETE batch operation using SAP UI5. I have done the insert batch operation. Its working fine. But delete batch operation is not working.

My INSERT Batch operation syntax

       update_entry.YEAR = year;
       update_entry.COUNTRY_ID = country;
       update_entry.CUSTOMER = name;

var batch_single =   insert_model.createBatchOperation('/customers',"POST",update_entry);   
                    batch_changes.push(batch_single) ;
insert_model.addBatchChangeOperations(batch_changes);
        insert_model.submitBatch(function() {
                                    update_success == "successful" ;}, function() {
                                    update_success == "unsuccessful";}, true);
                                insert_model.refresh();

I have modified the above code for the DELETE batch operation as below

    var batch_single =   insert_model.createBatchOperation('/customers',"DELETE",update_entry);

But the above syntax is not working. Could anyone help me with the issue.

Thanks Sathish

As opposed to the create operation, you'll need to pass the ID to the delete operation and not "entry":

var batch_single =   insert_model.createBatchOperation('/customers(1234)',"DELETE");`

I think changing from "POST" to "DELETE" will work, because you need a DELETE-request to push data to your backend.

First, check out this thread: SAPUI5 - Batch Operations - how to do it right?

I think the main-difference is your entity in createBatchOperation "/customers" - I think you have to change it to your service (e.g. "/sap/opu/odata/sap/MY_SERVICE/?$batch"). I found that then the batch is triggered, starting in this sequence:

1) /IWBEP/IF_MGW_CORE_SRV_RUNTIME~CHANGESET_BEGIN: SAP Proposal EXIT.
2) /iwbep/if_mgw_appl_srv_runtime~delete_entity. (n-times)
3)/iwbep/if_mgw_core_srv_runtime~changeset_end: SAP Proposal COMMIT WORK.

Second dont use '' and "" in the same statement (during createBatchOperation) - always use the same (if possible).

insert_model.createBatchOperation("/customers","POST",update_entry);
