博主在调用Webservice时遇到报错，经查找，问题原因是发布方设置不对。可通过soamanager的messenging，将message id （synchronous）设为suppress id transfer来解决，还给出了sap官方论坛的原文回答。

我在调用一个webservice的时候报错：MustUnderstand headers:[{http://schemas.xmlsoap.org/ws/2004/08/addressing}Action, {http://schemas.xmlsoap.org/ws/2004/08/addressing}To] are not understood。查了半天也没搞清楚原因，后来到sap官方论坛找到了答案

https://answers.sap.com/questions/8152784/webservice-doesnt-work-with-soapenvmustunderstand1.html，

问题原因应该是由于发布webservice方，有些设置不对导致：可以通过soamanager的messenging，设置message id （synchronous）为suppress id transfer。这样问题就解决了：

原文回答：

You can not modify the SOAP Request just like that. But it seems that your provider does not understand the WS-Addressing protocol properties. If this is synchrnous WS call ,you can try via soamanager to eclude addressing protocol via SOAMANAGER transaction.Find your logical port , go to Messaging Tab and set Message ID Protocol to "suppressTransfer".
