投影在 DAC 上带来重复数据

Question

我正在尝试创建一个投影，将 FSSODet 文件与 FSApppointmentDet 文件连接起来，以便在流程屏幕中使用。

这是我试图重现的 SQL：

SELECT FD.[SrvOrdType] ,FD.[RefNbr]
      ,FD.[OrigSrvOrdNbr],FD.[OrigLineNbr]
      ,FD.[UnitCost],FD.[UnitPrice]
      ,FS.[RefNbr] ,FS.[LineNbr]
      ,FS.[LineRef],FS.[UnitCost]
      ,FS.[UnitPrice],FS.[TranDesc]
      ,FS.[SODetID],FS.[SOID]
From [FSAppointmentDet] FD
   JOIN [FSSODet] FS on FD.OrigSrvOrdNbr = FS.RefNbr 
   AND FS.LineNbr = FD.OrigLineNbr
WHERE fs.UnitPrice <> FD.UnitPrice 

这就是我所拥有的：

[PXProjection(typeof(Select2<FSAppointmentDet,
    InnerJoin<FSSODet,
    On<FSSODet.refNbr, Equal<FSAppointmentDet.origSrvOrdNbr>,
       And<FSSODet.lineNbr, Equal<FSAppointmentDet.origLineNbr>>>>,
    Where<FSSODet.unitPrice, NotEqual<FSAppointmentDet.unitPrice>>>), Persistent = true)]
[PXCacheName("FixPriceProjection")]
public class PlyFixPriceProjDAC : IBqlTable
{
    #region Selected
    public abstract class selected : PX.Data.BQL.BqlBool.Field<selected> { }
    [PXBool]
    [PXUIField(DisplayName = "Selected")]
    public virtual bool? Selected { get; set; }
    #endregion

    #region Composite Key
    public class PK : PrimaryKeyOf<PlyFixPriceProjDAC>.By<origSrvOrdNbr, origLineNbr>
    {
        public static PlyFixPriceProjDAC Find(PXGraph graph, string origSrvOrdNbr, int? origLineNbr)
            => FindBy(graph, origSrvOrdNbr, origLineNbr);
    }

    public virtual Int32? InventoryID { get; set; }
    #endregion



    #endregion

    #endregion
    #endregion
}

当我运行此命令时，它选择了 1535 条记录，这是正确的。但所有记录都有相同的数据。

我将其放入图形代码中进行检查，发现计数正确，但数据不正确。

            public PXProcessing<PlyFixPriceProjDAC> Processing;

var Items = Processing.Select();
    var totRecords =  Items.Count;
    foreach (PlyFixPriceProjDAC item in Items)
    {
        var so = item.OrigSrvOrdNbr;
    }

知道为什么吗？

确保您在某些 dac 字段上定义了 IsKey=True，这种奇怪的情况是由于网格没有定义键
