需求要点：在单据A的界面点击“自动转换”，则自动产生审核态的单据B；若单据B不满足审核条件，则维持“提交”态；若单据B不满足保存校验，则维持“暂存”态；若转换失败，给出界面提示。

实现思路：
1.通过转换规则来定义单据A到单据B的转换关系，便于扩展，也便于使用已有的插件和服务；
2.定义一个空操作“自动转换”，扩展AbstractOperationServicePlugIn，重写EndOperationTransaction方法，方便处理事务；
3.依次调用单据转换服务、暂存服务、保存服务、提交服务和审核服务，以保证当前服务失败时能维持前一服务的状态;
4.根据上述服务调用的结果构造“自动转换”的操作结果；
5.若需求变更，只能生成审核态的单据B，否则不予生成，就要调用删除服务将所有审核不通过的单据删除，再构造操作结果；也可以直接抛出异常throw new KDBusinessException("", string.Join("\n", innerResult.ValidationErrors.Select(o => o.Message)))。

代码示例：

i++,"srcFormId");rows.Add(row);}OperateOption option = OperateOption.Create();option.SetVariableValue(BOSConst.CST_ConvertValidatePermission, true);PushArgs pushArgs = new PushArgs(ruleElement,
