从 Acumatica Framework 中的 SOShipLine 中删除行

Question

美好的一天，

我需要从“发货”屏幕上的 SOShipLine 中删除一行

我正在对 SOShipmentEntry 进行扩展，并尝试执行以下操作以删除该行

            PXResultset<SOShipLine> shipLines = SelectFrom<SOShipLine>.InnerJoin<SOShipment>.On<SOShipLine.shipmentNbr.IsEqual<SOShipment.shipmentNbr>>
            .Where<SOShipLine.shipmentNbr.IsEqual<@P.AsString>>.View.Select(Base, shipment.ShipmentNbr);

        List<Linelevel> lineLevels = osr.Transaction.Transaction.Order.LineLevel;


        foreach (SOShipLine shipLine in shipLines)
        {
            Linelevel lineLevel = lineLevels.Find(lineNbr => lineNbr.POLineNum == shipLine.LineNbr);
            if (lineLevel != null)
            {
                shipLine.ShippedQty = lineLevel.PickedQuantity;
            } else
            {
                Base.Transactions.Cache.Delete(shipLine);
            }
        }

但是当我到达要删除行的位置时，它会生成一个异常，询问我密钥不能为 null

尝试直接使用“交易”视图，而不是使用 PXSelect 查询数据。

// This is no longer needed - retrieve from the Transactions view instead
//PXResultset<SOShipLine> shipLines = SelectFrom<SOShipLine>.InnerJoin<SOShipment>.On<SOShipLine.shipmentNbr.IsEqual<SOShipment.shipmentNbr>>
//  .Where<SOShipLine.shipmentNbr.IsEqual<@P.AsString>>.View.Select(Base, shipment.ShipmentNbr);

List<Linelevel> lineLevels = osr.Transaction.Transaction.Order.LineLevel;

// Cycle through the records returned directly from the Transactions view
//foreach (SOShipLine shipLine in shipLines)
foreach (SOShipLine shipLine in Base.Transactions.Select())
{
    Linelevel lineLevel = lineLevels.Find(lineNbr => lineNbr.POLineNum == shipLine.LineNbr);
    if (lineLevel != null)
    {
        shipLine.ShippedQty = lineLevel.PickedQuantity;
    } else
    {
        // Generally speaking, work with the view instead of the cache when possible
        //Base.Transactions.Cache.Delete(shipLine);
        Base.Transactions.Delete(shipLine);
    }
}
// After your logic completes, make sure the user has to press Save or you do it for them
Base.Save.Press();

我通常只在处理不在视图中的其他一些数据时才直接使用缓存，例如将引用值推送到在别处管理的记录中。即便如此，我更喜欢在图形扩展中创建一个视图并使用它。
