Suggestion :

In interopProvider.c, while creating instance using "InteropProviderCreateInstance" function. It gets all the properties of CIM_IndicationFilter instance like "querylanguage", "query", and finally "SourceNamespace". It uses "st" to get the status. In our case "SourceNameSpace" is not available and thus st will set with "CMPI_RC_ERR_NOT_FOUND". The function continues and when sns is NULL it sets "root/interop" as the namespace. Finally it adds the filter in the global list. When it tries to add it in the repository st is not set as CMPI_RC_OK and it returnd the error code 6 as response.

Note: When we use the same command to create the instance, it checks in the global list and return "CMPI_RC_ERR_ALREADY_EXIST" with error code 11.
