BI Query Wizard error 32010 (400) bad http request

Hello,

if we try to preview the result of a query in the BI Query Wizard of VC we get following error:

"Error -32010: Cannot execute query. No

result returned or XML returned in the result

contains an error. Service call exception;

nested exception is:

com.sap.engine.services.webservices.jaxrpc.ex

Invalid Response Code: (400) bad http

request.."

In the trace file of the ICM in the BW system we found the following error:

"[Thr 10] Wed Apr 26 16:14:45 2006

[Thr 10] *** ERROR => Error in HTTP Request: 11 [http_plg_mt.c 4014]

[Thr 10] *** ERROR => PlugInHandleNetData: HttpParseRequestHaeder failed (rc=-701) [http_plg_mt. 1917]"

I've searched the forum for an error like this but the only errors I could find were about the Http-error 404.

We have the following configuration:

- EP 6.0.11.3.0 SPS 11 Patch 3

- BW 3.5 Support Package 15

What is wrong with this?

Any help would be appreciated.

Best regards, Michael
