Acumatica - 如何从客户中的自定义字段更新客户位置中的自定义字段

Question

我尝试了几种不同的方法来做到这一点，每种方法都有一段代码我只是不正确。如果在客户交付选项卡中更新，我需要更新客户位置中的自定义字段 UsrCustomerShipAccount。我尝试了 SetValueExt 并创建了一个图形实例。抱歉这个愚蠢的问题。 似乎让我最接近的方式如下：

protected void LocationExtAddress_UsrCustomerShipAccnt_FieldUpdated(PXCache cache, PXFieldUpdatedEventArgs e, PXFieldUpdated InvokeBaseHandler)
{
    if(InvokeBaseHandler != null)
        InvokeBaseHandler(cache, e);
    var row = (LocationExtAddress)e.Row;

    if (row == null) return;

    PXSelectBase<Location> locationObj = new PXSelect<Location, Where<Location.bAccountID, Equal<Required<Location.bAccountID>>>>(Base);
    Location deliveryLocation = locationObj.Select(row.LocationBAccountID);
    var locationExt = PXCache<Location>.GetExtension<LocationExt>(location);  <-- This generates error that there is no LocationExt.

    deliveryLocation.Cache.SetValueExt(deliveryLocation, "UsrCustomerShipAccount", -->This needs to be the value that changed LocationExtAddress.UsrCustomerShipAccount but I don't see how to get this<--);
    deliveryLocation.Cache.IsDirty = true;
    deliveryLocation.Update(deliveryLocation);  <--I don't know if this doesn't work because it is wrong or if it is because "UsrCustomerShipAccount" is not in deliverLocation.
}

你有

var locationExt = PXCache<Location>.GetExtension<LocationExt>(location);

不应该这样吗

var locationExt = PXCache<Location>.GetExtension<LocationExt>(deliveryLocation );
