如何将订单项自定义字段值从机会传递到销售订单？

我在机会产品选项卡中有一个自定义行号字段，供客户对所选产品重新排序，并且网格按自定义字段值排序。

我试图将机会的价值传递给也具有类似字段的销售订单。

我尝试过以下代码但它不起作用

            PXGraph.InstanceCreated.AddHandler<SOOrderEntry>((graph) =>
            {
                graph.RowUpdated.AddHandler<SOLine>((cache, args) =>
                    {

                        CROpportunityProducts product = (adapter.View.Graph as OpportunityMaint).Products.Current;
                        CROpportunityProductsExtNV productext = PXCache<CROpportunityProducts>.GetExtension<CROpportunityProductsExtNV>(product);
                        SOLine soline = (SOLine)args.Row;
                        SOLineExtNV solineext = PXCache<SOLine>.GetExtension<SOLineExtNV>(soline);
                        solineext.UsrLineNo = productext.UsrLineNo;

                    });
            });

以下代码段为所有行号返回相同的值

您可以实现 RowInserting 事件处理程序，如下所示：

graph.RowInserting.AddHandler<SOLine>((cache, args) =>
{
    var soLine = (SOLine)args.Row;
    CROpportunityProducts opProduct = PXResult<CROpportunityProducts>.Current;
    SOLineExtNV soLineExt = PXCache<SOLine>.GetExtension<SOLineExtNV>(soLine);
    CROpportunityProductsExtNV opProductExt = PXCache<CROpportunityProducts>.GetExtension<CROpportunityProductsExtNV>(opProduct);
    soLineExt.UsrLineNo = opProductExt.UsrLineNo;
});
