二开案例.下推时修改下游单据的单据编号

单据转换规则，testAA下推testBB，testBB设置了编码规则：

下推时，testBB会按编码规则生成编码

在转换规则上挂插件，修改单据编号

using Kingdee.BOS.Core.Metadata.ConvertElement.PlugIn;
using Kingdee.BOS.Core.Metadata.ConvertElement.PlugIn.Args;

namespace Test202408
{
    [Kingdee.BOS.Util.HotUpdate]
    public class 下推时设置单据编码 : AbstractConvertPlugIn
    {
        public override void AfterConvert(AfterConvertEventArgs e)
        {
            var entity = e.TargetBusinessInfo.GetEntity(0);
            var targetDataEntities = e.Result.FindByEntityKey(entity.Key);

            foreach (var targetDataEntity in targetDataEntities)
            {
                var billNo = "test11222";
                var billNoField = e.TargetBusinessInfo.GetBillNoField();
                targetDataEntity.DataEntity[billNoField.PropertyName] = billNo;
            }
        }
    }
}

再次下推，单据编号修改成功
