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);
