Acumatica 如何将库存可用性状态添加到自定义网格（如SO301000）

我们正在添加一个自定义屏幕，该屏幕利用页面上定义的网格行中的站点ID和库存ID。我们希望添加库存可用性详细信息，如SO301000销售订单条目图所示

A如何访问网格的状态区域以放置文本。 B对于SO301000上使用的文本，是否有一个标准方法可供访问。

该功能称为StatusField

您可以在网格ASPX控件上定义状态字段：

<px:PXGrid ID="grid" runat="server" DataSourceID="ds" StatusField="Availability">

Sales order（销售订单）屏幕将其与allocation custom data view（分配自定义数据视图）混为一谈，这使得其难以重复使用：

public LSSOLine lsselect;

在LSSOLine类中，您可以找到计算该值的Availability_FieldSelecting方法：

public override void Availability_FieldSelecting(PXCache sender, PXFieldSelectingEventArgs e)
{
    var fetchMode = ((SOLine) e.Row)?.Completed == true
        ? AvailabilityFetchMode.None
        : AvailabilityFetchMode.ExcludeCurrent;
    IQtyAllocated availability = AvailabilityFetch(sender, (SOLine)e.Row, fetchMode | AvailabilityFetchMode.TryOptimize);

    if (availability != null)
    {
        PXResult<InventoryItem, INLotSerClass> item = ReadInventoryItem(sender, ((SOLine)e.Row).InventoryID);

        decimal unitRate = INUnitAttribute.ConvertFromBase<SOLine.inventoryID, SOLine.uOM>(sender, e.Row, 1m, INPrecision.NOROUND);
        availability.QtyOnHand = PXDBQuantityAttribute.Round((decimal)availability.QtyOnHand * unitRate);
        availability.QtyAvail = PXDBQuantityAttribute.Round((decimal)availability.QtyAvail * unitRate);
        availability.QtyNotAvail = PXDBQuantityAttribute.Round((decimal)availability.QtyNotAvail * unitRate);
        availability.QtyHardAvail = PXDBQuantityAttribute.Round((decimal)availability.QtyHardAvail * unitRate);

        if(IsAllocationEntryEnabled)
        {
            Decimal? allocated = PXDBQuantityAttribute.Round((decimal)(((SOLine)e.Row).LineQtyHardAvail ?? 0m) * unitRate); ;
            e.ReturnValue = PXMessages.LocalizeFormatNoPrefix(Messages.Availability_AllocatedInfo,
                    sender.GetValue<SOLine.uOM>(e.Row), FormatQty(availability.QtyOnHand), FormatQty(availability.QtyAvail), FormatQty(availability.QtyHardAvail), FormatQty(allocated));
        }
        else
            e.ReturnValue = PXMessages.LocalizeFormatNoPrefix(Messages.Availability_Info,
                    sender.GetValue<SOLine.uOM>(e.Row), FormatQty(availability.QtyOnHand), FormatQty(availability.QtyAvail), FormatQty(availability.QtyHardAvail));


        AvailabilityCheck(sender, (SOLine)e.Row, availability);
    }
    else
    {
        //handle missing UOM
        INUnitAttribute.ConvertFromBase<SOLine.inventoryID, SOLine.uOM>(sender, e.Row, 0m, INPrecision.QUANTITY);
        e.ReturnValue = string.Empty;
    }

    base.Availability_FieldSelecting(sender, e);
}

我建议跳过使用LSSOLine，只复制它的fieldselection方法

该方法在另一个答案中有更详细的记录：

在我的用例中，尝试重用LSSOLine似乎是一个相当具有挑战性的问题。如果可以在标准代码中修改可用性以允许类似字符串availability=GetAvailabilityint这样的内容，那就太好了？目录ID，int？子项ID，int？siteID，SOLine sOLinel，这样我们就可以进行标准调用，并可以在SOLine与null相关时选择性地传递SOLine。null只是获取当前可用性。但现在，我将使用您指向Brendan发布的代码示例作为基础，并尝试合并您的文章中所示的数据/格式以保持一致性。再次感谢！
