SAP BAPI事务未从WCF提交

Question

从我的WCF服务，我需要在SAP系统中创建一个采购订单，它正在创建。但是当我尝试提交事务时，它在SAP系统中不起作用。

我正在从SAP获取PONumber，但它没有提交。

在这个问题上，有人能帮我吗？

下面是我的代码：

NFCLMasters.ZMASTERDATA zmobj = new NFCLMasters.ZMASTERDATA();
            NFCLMasters.ZMASTERDATAResponse zmresponse = new NFCLMasters.ZMASTERDATAResponse();
            NFCLMasters.ZSM_WH_MST[] zmwarehousemaster = new NFCLMasters.ZSM_WH_MST[10];
            NFCLMasters.zws_mst mst = new NFCLMasters.zws_mst();
            zmobj.IWHMST = "X";
            zmobj.WHMST_LINES = zmwarehousemaster;
            zmresponse = mst.ZMASTERDATA(zmobj);

您的两个BAPI调用当前在单独的上下文中执行。因此，对BAPI_TRANSACTION_COMMIT的第二个调用将无法工作，因为第二个调用上下文不知道第一个调用的任何结果。您需要在同一上下文中执行这两个调用。我不知道如何使用旧的、不推荐使用的SAPNCO3连接器，但是使用当前的SAPNCO3，您可以使用RfcSessionManager.BeginContext()和RfcSessionManager.EndContext()方法来实现它。

如果只将BAPI公开为web服务，则提交可能不会成功，因为对这些web服务的所有调用都是在它们自己的上下文中执行的，因此您又遇到了同样的问题。使用web服务和BAPI_TRANSACTION_COMMIT的一种变通办法是在SAP系统中创建一个自定义函数模块，该模块首先调用您的BAPI，如果调用成功，则调用BAPI_TRANSACTION_COMMIT。该功能模块必须具有RFC功能，并且可以作为web服务为您公开。该自定义函数模块的参数将(至少)与您需要的BAPI的参数相同，可能是一个额外的"COMMIT“参数，允许您在不提交任何内容的情况下调用它。创建这样的功能模块相对容易，对于熟悉SAP ERP的公司来说应该不是问题。
