HTTP 500 exception in SAP Web Service

In the last two days, an error was reported when the user used the device to query the mobile platform. The middleware platform reported that after the request was sent, the system reported an error in http500 and did not receive the query result.

If the device number is used separately and the branch number is used separately, an error is returned after the date is added.

It is completely normal to test the Web service interface through the soap UI separately.

In RM, srt_util is enabled to track the request and response of the web service. It is indeed a response error.

Intuitively, is it because of the date parameter? Is it because of the date parameter that is called externally? Cannot the CRM system receive it? Because you use the soap UI to test with your own account, the date format in XML must be entered as a YYYY-MM-DD to get the results, otherwise it will report an exception. If you enter yyyy/mm/dd Or YYYY. Mm. DD, the date format cannot be processed.

Later, I changed the date format of the mobile account, but it actually solved the problem. It can be seen that when SAP Web Service encapsulates parameters such as date, it is related to the personal parameters of the user account that calls web service.
