Error 'HTTP status code 400 Bad Request' while executing HTTP request (calling method 'get_status')

[Former Member]

Hi Experts,

I am trying to refresh cache on PI system (NW 7.4 Dual stack) using the transaction SXI_CACHE.

I am receiving the error message as [ Error 'HTTP status code 400  Bad Request' while executing HTTP request (calling method 'get_status') ] This is appearing on the main screen as soon as I execute SXI_CACHE.

Kindly help on this,,,

Thanks and regards,

Arun

Hi Arun,

Please check SAp Note # 1894606

1) HTTP response does not contain a valid XML root tag or Error 'HTTP status code 400 Bad Request' while executing HTTP request (calling method 'get_status')

The error 'HTTP response does not contain a valid XML root tag' occurs when path prefix of the destination is '/dir/hmi_cache_refresh_service/ext'.

The error 'Error 'HTTP status code 400 Bad Request' while executing HTTP request (calling method 'get_status')' when path prefix is '/dir/CacheRefresh'.

Solution: Go to transaction sm59 and open destination of type 'H' INTEGRATION_DIRECTORY_HMI. Select "Connection Test". The connection test should return HTTP response 200.

Now go to "Logon & Security" tab and ensure that username and password are stored in the system. Fixing credentials should fix the problem.

Note: Credentials cannot be tested via "Connection Test" tool. If used credentials are wrong, the server simply returns login html page (using HTTP response code 200). As the login html page is not a valid cache refresh xml document, an error is shown in sxi_cache.

Hi Azhar,

Thanks for your reply.

We have checked SAP Note 1894606 - HTTP errors in sxi_cache,

Problem still same.

Thanks and regards,

Can you go to sxi_cache and hit F7? This should let you know if there is anything wrong with the configuration.

Also may i know the user you have configured in RFC destination? It should be system user with below roles.

• SAP_XI_CACHE_SERV_USER
• SAP_BC_WEBSERVICE_PI_CFG_SRV
• SAP_SLD_CONFIGURATOR

Hi Hareesh,

Did you maintain the correct password? password status shows " is initial". if you have given some password then i believe it should display as "saved"

Hi Hareesh,

Now password has reset and updated in RFC, Error Status HTTP Response 403 - Forbidden.

Thanks and regards,

As per the note 1894606 - HTTP errors in sxi_cache

One more workaround currently exists for this problem: Go to sm59 and open INTEGRATION_DIRECTORY_HMI destination. Use following path there:

"/dir/hmi_cache_refresh_service/ext". Do not forget to re-enter password on "Logon & Security" tab, otherwise you might get 'HTTP response does not contain a valid XML root tag' error described above. Save the destinaion and retry the cache refresh

Try if that works..

Hi Hareesh,

I have changed Path given, Now RFC "OK", SXI_CACHE same 400 error.

Can you also share the screenshot of sxi_cache (F7) ?

Sure,

I see that cache status is up to date? if you refer to your previous screenshots it has got some inconsistencies.

You can try making a dummy change in ID and see if the cache get's updated.

Hi Hareesh,

Thank for your support, Issue solved by changing path = "/dir/hmi_cache_refresh_service/ext".

Now it's working properly (SXI_CACHE) .
