我想知道是否可以覆盖DefaultEndpointImpl.cs或在另一个文件中添加我自己的API逻辑？
我正在苦苦挣扎一些API调用，这些调用要求覆盖或添加此文件中的逻辑。例如，我能够通过api成功创建采购订单的采购收据，但是我无法以相同的方式添加“转移收据”采购收据。
我在API端点中包含了各种非标准字段，这些字段引用了原始的转移，转移订单和装运，但是没有成功。 API调用成功，但未添加任何行。生成行后，我已经能够更新它们的数量，但是无法添加或删除当前行。
问题似乎源于此代码，该代码似乎添加了可以正确处理添加图形的购买订单行逻辑的功能，但对其他收货类型没有任何特殊作用。

protected void PurchaseReceiptDetail_Insert(PXGraph graph, EntityImpl entity, EntityImpl targetEntity) {
var receiptEntry = (POReceiptEntry)graph;
var lineNbr = targetEntity.Fields.SingleOrDefault(f => f.Name == "POLineNbr") as EntityValueField;
var orderType = targetEntity.Fields.SingleOrDefault(f => f.Name == "POOrderType") as EntityValueField;
var orderNbr = targetEntity.Fields.SingleOrDefault(f => f.Name == "POOrderNbr") as EntityValueField;
bool insertViaAddPO = lineNbr != null && orderNbr != null && orderType != null;
if (!insertViaAddPO && (lineNbr != null || orderType != null || orderNbr != null)) {
throw new PXException(PO.Messages.POTypeNbrLineNbrMustBeFilled);
}
var detailsCache = receiptEntry.transactions.Cache;
if (insertViaAddPO) {
receiptEntry.filter.Cache.Remove(receiptEntry.filter.Current);
receiptEntry.filter.Cache.Insert(new POReceiptEntry.POOrderFilter());
var filter = receiptEntry.filter.Current; var state = receiptEntry.filter.Cache.GetStateExt(filter, "OrderType") as PXStringState;
if (state != null && state.AllowedLabels.Contains(orderType.Value)) {
orderType.Value = state.ValueLabelDic.Single(p => p.Value == orderType.Value).Key;
}
receiptEntry.filter.Cache.SetValueExt(filter, "OrderType", orderType.Value);
receiptEntry.filter.Cache.SetValueExt(filter, "OrderNbr", orderNbr.Value);
receiptEntry.filter.Update(filter);
var orders = receiptEntry.poLinesSelection.Select().Select(r => r.GetItem<POReceiptEntry.POLineS>());
var order = orders.FirstOrDefault(o => o.LineNbr == int.Parse(lineNbr.Value));
if (order == null) {
throw new PXException(PO.Messages.PurchaseOrderLineNotFound);
}
order.Selected = true;
receiptEntry.poLinesSelection.Update(order);

答案 0 :(得分：0)
经过反复的尝试，我设法使所有功能按需运行。但是，我担心的是，由于这不是记录在案的信息，因此在不久的将来可能会发生更改。
DefaultEndpointImpl类中的方法是通过反射调用的。为了为我的默认端点添加自定义功能，我扩展了默认类并为我的类和函数添加了必要的属性。
我的自定义类添加了以下内容：
第一个很简单，我对结果感到满意。第二个程序花了很多时间并调试正确，它很hacky，可能不适用于串行跟踪的项目。花费这么长时间的原因是因为有许多未知数，而我实际上一直在根据基类中的代码进行猜测。例如，我什至不确定该函数在哪个阶段触发。看起来功能完全覆盖了其他一些不可见的默认逻辑。
因此，不管它还是离开它！也许我会联系Acumatica，看看是否可以获得更多信息。
