use the following link to test filter logic: ( filter by status = open )
https://:4080/sap/opu/odata/sap/CRM_OPPORTUNITY/Opportunities?$skip=0&$top=20&$filter=UserStatusCode eq 'I1002'
in this case get_system_status will never be called:

instead, the filter option passed by the consumer will be handled:

However, in the result list, E0001 is filled instead of I1002.

trace如下代码：

首先读出所有的CRM status：

此处会将I1002对应的status转换成E0001：
