代码实现新增单据带树形单据体 - 不推荐

场景：

通过代码为某单据新增一条数据，带树形单据体

实现：

DynamicObject data = BusinessDataServiceHelper.newDynamicObject("单据标识");

data.set("billno", "963");

DynamicObjectCollection treeentryentity = data.getDynamicObjectCollection("kdec_treeentryentity");

DynamicObject treeentry = new DynamicObject(treeentryentity.getDynamicObjectType());

Long id = DBServiceHelper.genLongIds("tk_demo_tree", 1)[0];//tk_demo_tree为树形单据体表名

//**原因是树形单据体存在父子层级结构关系，必须设置pid以保证树形结构展示，故我们通过代码生成该单据体行数据的主键为了下一步设置pid

treeentry.set("Id", id);//设置该父行主键

treeentry.set("kdec_textfield2", "new year");

treeentry.set("kdec_integerfield2", 999);

DynamicObject treeentrySon = new DynamicObject(treeentryentity.getDynamicObjectType());

treeentrySon.set("pid",id);//设置该行的父行

treeentrySon.set("kdec_textfield2", "happy");

treeentrySon.set("kdec_integerfield2", 111);

treeentryentity.add(treeentry);

treeentryentity.add(treeentrySon);

Object[] ids = SaveServiceHelper.save(new DynamicObject[] {data});

效果：

思考?

为什么一定要新增带有id的父行
