Batch request Batch request A batch request allows us grouping multiple operations in one single request. batch mode has to be enabled for this. You can do this by enabling it via the function setUseBatch this . _oServiceModel . setUseBatch ( true ) ; or in your manifest.json "" : { "dataSource" : "mainService" , "preload" : true , "settings" : { "useBatch" : true } } So here’s a coding sample with an batchGroupId sampleBatchRequest : function ( ) { //Get all GroupId's var aDeferredGroup = this . _oServiceModel . getDeferredGroups ( ) ; //Add a new Group Id aDeferredGroup . push ( "doSomething" ) ; this . oServiceModel . setDeferredGroups ( aDeferredGroup ) ; //Create Parameters var oParameters = { groupId : "doSomething" } ;...
