如何修改销售订单屏幕的位置选择器

Question

我有一个在销售订单屏幕上向位置选择器添加字段的请求。在标准 Acumatica 风格中，这不是典型的选择器，而是我以前从未见过的：

[LocationID(typeof(Where<Location.bAccountID, Equal<Current<SOOrder.customerID>>,
                   And<Location.isActive, Equal<True>,
                   And<MatchWithBranch<Location.cBranchID>>>>)
            ,DescriptionField = typeof(Location.descr)
            ,Visibility = PXUIVisibility.SelectorVisible)]

我需要添加的字段是 Address1、Address2、City、State、Zip。我如何将这些字段添加到这个名为“LocationID”的神秘选择器中？

这个我试过了，还是不行：

    [PXRemoveBaseAttribute(typeof(LocationIDAttribute))]
    [PXMergeAttributes(Method = MergeMethod.Append)]
    [PXSelector(typeof(Search2<Location.locationID, 
                               InnerJoin<Address, 
                                   On<Location.defAddressID, Equal<Address.addressID>>>,
                       Where<Location.bAccountID, Equal<Current<SOOrder.customerID>>,
                       And<Location.isActive, Equal<True>,
                       And<MatchWithBranch<Location.cBranchID>>>>>)
                ,typeof(Location.locationCD)
                ,typeof(Address.addressLine1)
                ,typeof(Address.addressLine2)
                ,typeof(Address.city)
                ,typeof(Address.state)
                ,typeof(Address.postalCode)
                ,SubstituteKey = typeof(Location.locationCD)
                ,DescriptionField = typeof(Location.descr))]
    protected virtual void SOOrder_CustomerLocationID_CacheAttached(PXCache sender) { }

这个有点棘手，因为更改列列表的能力受到保护。我们可以通过创建我们自己的位置 ID 属性来更改列，该属性继承我们需要更改的属性，然后替换维度选择器，那时我们可以添加要显示的列。我们还需要加入地址表以显示您要添加的字段，因为它们不在 Location DAC 中。

以下是工作示例：

我们将使用一个新属性来替换 SOOrder CustomerLocaitonID 上的当前属性

public class LocationIDExtensionAttribute : LocationIDAttribute
{
    public LocationIDExtensionAttribute(params Type[] fieldList)
        : this(typeof(Where<boolTrue, Equal<boolTrue>>), fieldList)
    {
    }

    public LocationIDExtensionAttribute(Type WhereType, params Type[] fieldList)
        : base(WhereType)
    {
        AddColumns(WhereType, fieldList);
    }

    public LocationIDExtensionAttribute(Type WhereType, Type JoinType, params Type[] fieldList)
        : base(WhereType, JoinType)
    {
        AddColumns(WhereType, JoinType, fieldList);
    }

    protected void AddColumns(Type WhereType, params Type[] fieldList)
    {
        var dimensionSelector = _Attributes[_SelAttrIndex];
        if (dimensionSelector == null)
        {
            return;
        }

        _Attributes[_SelAttrIndex] = (PXEventSubscriberAttribute)new PXDimensionSelectorAttribute("LOCATION", BqlCommand.Compose(typeof(Search<,>), typeof(Location.locationID), WhereType), typeof(Location.locationCD), fieldList);
    }

    protected void AddColumns(Type WhereType, Type JoinType, System.Type[] fieldList)
    {
        var dimensionSelector = _Attributes[_SelAttrIndex];
        if (dimensionSelector == null)
        {
            return;
        }

        _Attributes[_SelAttrIndex] = (PXEventSubscriberAttribute)new PXDimensionSelectorAttribute("LOCATION", BqlCommand.Compose(typeof(Search2<,,>), typeof(Location.locationID), JoinType, WhereType), typeof(Location.locationCD), fieldList);
    }
}

然后我们会像这样使用这个属性：

[LocationIDExtension(typeof(Where<Location.bAccountID, Equal<Current<SOOrder.customerID>>,
        And<Location.isActive, Equal<True>,
            And<MatchWithBranch<Location.cBranchID>>>>),
    typeof(LeftJoin<Address, On<Location.defAddressID, Equal<Address.addressID>>>), 
    typeof(Location.locationCD),
    typeof(Location.descr), 
    typeof(Address.addressLine1), 
    typeof(Address.addressLine2), 
    typeof(Address.city),
    typeof(Address.state), 
    typeof(Address.postalCode), 
    DescriptionField = typeof(Location.descr),
    Visibility = PXUIVisibility.SelectorVisible)]

我们最终得到了这个：
