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:
[code]public override void EndOperationTransaction(BOS.Core.DynamicForm.PlugIn.Args.EndOperationTransactionArgs e)
{
base.EndOperationTransaction(e);

foreach (var srcData in e.DataEntitys)
{
ListSelectedRow row = new ListSelectedRow(srcData.GetDynamicObjectItemValue("Id"), string.Empty, i++,"srcFormId");
rows.Add(row);
}
OperateOption option = OperateOption.Create();
option.SetVariableValue(BOSConst.CST_ConvertValidatePermission, true);
PushArgs pushArgs = new PushArgs(ruleElement, rows.ToArray());
// 转换生成目标单
ConvertOperationResult convResult = AppServiceContext.ConvertService.Push(this.Context, pushArgs, option);
