Axapta 如何从AX 2012零售POS中的代码在屏幕上加载交易

我们要求在

显示日记帐

屏幕上为用户提供

复制交易

按钮，点击此按钮将在主POS屏幕上加载所选交易的准确信息，出纳可以进行投标和结算

我在表单上创建了一个按钮，在按钮的单击事件中，我使用以下代码加载并启动了事务对象：

 if (gridView1.SelectedRowsCount > 0)
            {
                DataRow Row = gridView1.GetDataRow(gridView1.GetSelectedRows()[0]);
                selectedTransactionId = (string)Row["TRANSACTIONID"];
                selectedStoreId = (string)Row["STORE"];
                selectedTerminalId = (string)Row["TERMINAL"];

                PosTransaction transaction = LoadTransaction(selectedTransactionId, selectedStoreId, selectedTerminalId);


            }

this.Application.BusinessLogic.SuspendRetrieveSystem.SuspendTransaction(transaction);

this.Application.BusinessLogic.SuspendRetrieveSystem.RetrieveTransaction(transaction.TransactionId);

现在我找不到将此事务加载到主屏幕的方法，我已尝试设置

this.posTransaction=transaction但它不起作用

然后我尝试挂起事务并检索挂起的事务，我可以通过以下代码成功挂起事务：

 if (gridView1.SelectedRowsCount > 0)
            {
                DataRow Row = gridView1.GetDataRow(gridView1.GetSelectedRows()[0]);
                selectedTransactionId = (string)Row["TRANSACTIONID"];
                selectedStoreId = (string)Row["STORE"];
                selectedTerminalId = (string)Row["TERMINAL"];

                PosTransaction transaction = LoadTransaction(selectedTransactionId, selectedStoreId, selectedTerminalId);


            }

this.Application.BusinessLogic.SuspendRetrieveSystem.SuspendTransaction(transaction);

this.Application.BusinessLogic.SuspendRetrieveSystem.RetrieveTransaction(transaction.TransactionId);

但无法使用以下代码检索此事务：

 if (gridView1.SelectedRowsCount > 0)
            {
                DataRow Row = gridView1.GetDataRow(gridView1.GetSelectedRows()[0]);
                selectedTransactionId = (string)Row["TRANSACTIONID"];
                selectedStoreId = (string)Row["STORE"];
                selectedTerminalId = (string)Row["TERMINAL"];

                PosTransaction transaction = LoadTransaction(selectedTransactionId, selectedStoreId, selectedTerminalId);


            }

this.Application.BusinessLogic.SuspendRetrieveSystem.SuspendTransaction(transaction);

this.Application.BusinessLogic.SuspendRetrieveSystem.RetrieveTransaction(transaction.TransactionId);

我知道我可以逐个读取项目并将其添加到交易中，但如果对交易应用了折扣，或者交易是忠诚交易，那么我必须重新加载准确的交易。
您尝试过吗

if (!string.IsNullOrEmpty(this.selectedTransactionId)) {
    application.RunOperation(PosisOperations.RecallTransaction, this.selectedTransactionId);
}
