Make batch calls with multiple changeset ids in SAP UI5

Hello,

There are use cases where you might need to send multiple create, edit and delete request in a single batch. By default UI5 send the multiple request in a single batch with same change sets ids. So if any record fails, all the records are rolled back if changeset is not handled in backend.

With this blog I will show you, how you can send multiple CRUD operation in a single batch with different changeset ids. With different changeset ids all the records will be independent of each other.

Create a master map with following parameter

var mParameter = {
				
				urlParameters: null,
				groupId:"randomgroupid",
				success: function(innerdata) {

//This success handler will only be called if batch support is enabled. 
//If multiple batch groups are submitted the handlers will be called for every batch group.
			
				},
				error: function(oError) {
				
				}
			};

Create a map for each entry with following parameters

	var singleentry = {
				groupId: "randomgroupid",
				urlParameters: null,
				success: function(innerdata) {
					
				//The success callback function for each record
					
				},
				error: function(oError) {

				//The error callback function for each record
			};

For my current use case am reading a complete record from a sap.ui.table and sending it as a POST

//data model contains the table data
//Assign unique changeset id to singleentry
for (var i = 0; i < data.BP.length; i++) {
				singleentry.properties= data.BP[i];

				singleentry.changeSetId="changeset "+i;
				this.getOwnerComponent().getModel().createEntry("/Entity", singleentry);
			}

Finally submit the changes

this.getOwnerComponent().getModel().submitChanges(mParameter);
