1、续73.2，采购订单和收料通知单，添加多选辅助资料字段 F_PAEZ_MulAssistantGGB ，

注意标识、字段名、绑定实体属性一样

2、续73.3，添加类 MulBaseConvPlug

3、添加 public

4、添加引用

using System;
using System.Collections.Generic;
using System.ComponentModel;
using Kingdee.BOS.Core.Metadata;
using Kingdee.BOS.Core.Metadata.ConvertElement.PlugIn;
using Kingdee.BOS.Core.Metadata.ConvertElement.PlugIn.Args;
using Kingdee.BOS.Core.Metadata.EntityElement;
using Kingdee.BOS.Orm.DataEntity;
using Kingdee.BOS.Contracts;
using Kingdee.BOS.App;
using Kingdee.BOS.Core.Metadata.FieldElement;
using System.Linq;

5、添加说明 [Description("多选辅助基础资料插件")]

6、添加继承 : AbstractConvertPlugIn

7、复制固定写法的代码，修改字段标志成上面多选辅助资料的 F_PAEZ_MulAssistantGGB

8、和上一节区别，MulBaseDataField修改类型为 MulAssistantField

9、注册插件，具体操作请参考上一节

10、最终效果，采购订单下推收料通知单，带出多选辅助资料
