为什么我的操作比当前过滤的记录影响更多？

如何解决为什么我的操作比当前过滤的记录影响更多？

我用我自己的一个覆盖了 Records 上的 ARSalesPriceMaint 数据视图，以便也覆盖数据视图委托 records。这是必要的，因为我已经自定义了页面过滤器。 效果很好。

我添加了一个操作，该操作应获取结果记录（过滤后）并更新 DAC 扩展中的自定义字段。这确实会更新记录，但它不尊重记录上的过滤器，尤其是网格过滤器。例如，过滤 UOM 列会影响视图，但我的操作会更新所有 UOM。

所以这是问题：为什么我的操作的 foreach 语句被赋予的记录多于网格中的记录？

我相信这是问题区域，但整个代码也在下面：

（这是来自 UpdateDifs 操作，而不是数据视图委托）

foreach (PXResult<ARSalesPrice> result in Records.View.Select(null,null,PXView.Searches,Base.Records.View.GetExternalSorts(),Base.Records.View.GetExternalDescendings(),Base.Records.View.GetExternalFilters() ?? new PXFilterRow[0],ref startRow,ref totalRows))
        {
            // more code
        }

完整代码：

解决方法

事实证明这不是代码错误的操作。

对数据视图委托的以下更改已解决该问题：

var records = Base.Records.View.Select(PXView.Currents,filterParams,PXView.Searches,PXView.SortColumns,PXView.Descendings,Records.View.GetExternalFilters(),ref startRow,ref totalRows);
