SAPUI5-批处理操作-如何正确执行? [英] SAPUI5 - Batch Operations - how to do it right?

问题描述

我在SAP后端中有多个要更新的EntititySets，因此我将数据(有效负载)作为JSON提取并放入请求中(成功在数据"节点中):

I got multiple EntititySets which I want to update in my SAP Backend, therefore I fetch my data (payload) as JSON and put it in a request (its successfully in the node "data"):

代码:

var oTreeJSON = oTreeTable.getModel().getProperty("/root");
var oModel = sap.ui.getCore().getModel();
var batchChanges = [];  

for (var i = 0; i < oTreeAll.length; i++) {
    batchChanges.push(oModel.createBatchOperation("/sap/opu/odata/sap/MY_SERVICE/?$batch", "POST", oTreeAll[i]));
}

oModel.submitBatch();

我的请求如下:

它应该到达SAP的什么位置(哪种方法)?我在做什么错，哪里都没有错误，但是没有电话接到我的后端……对每一个提示都很高兴！谢谢.

Where should it arrive in SAP (which method)? What am I doing wrong, there is no error anywhere, but no call arrived in my backend... Glad about every hint! Thanks.

工作示例，降低了复杂性:

var oEntry = {};
oEntry.MyId = "00000001";
oEntry.Value = "300";

batchChanges.push(oModel.createBatchOperation("MyEntitySet", "POST", oEntry, null));
oModel.addBatchChangeOperations(batchChanges); 
oModel.setUseBatch(true);
oModel.submitBatch();

为进行记录，方法调用:

For the record, method calls:

• 1)/IWBEP/IF_MGW_CORE_SRV_RUNTIME〜CHANGESET_BEGIN:SAP投标退出.
• 2)/iwbep/if_mgw_appl_srv_runtime〜create_entity. (n次)//做你的 实体的东西
• 3)/iwbep/if_mgw_core_srv_runtime〜changeset_end:SAP提案提交 工作.

• 1) /IWBEP/IF_MGW_CORE_SRV_RUNTIME~CHANGESET_BEGIN: SAP Proposal EXIT.
• 2) /iwbep/if_mgw_appl_srv_runtime~create_entity. (n-times) // do your stuff with the entity
• 3) /iwbep/if_mgw_core_srv_runtime~changeset_end: SAP Proposal COMMIT WORK.

推荐答案

oModel.addBatchChangeOperations(batchChanges);
oModel.setUseBatch(true);

如果您需要在后端为批处理操作设置一个断点，只需在方法CHANGESET_BEGIN或CHANGESET_END中设置一个断点.

In case you need set a breakpoint in backend for batch operations, just set a break point in method CHANGESET_BEGIN or CHANGESET_END.
