Error after schudling report for triggring proxy

Hi friends,

In the scnario proxy-jdbc.. i have moved the interface to production and schudled the abap report in background jobs.

now when the report is triggered the proxy is called and here i am getting this error.

INTERNAL.CLIENT_RECEIVE_FAILED Error while receiving by HTTP (error code: 400, error text: ICM_HTTP_CONNECTION_FAILED)

and same report works when i execute manually. and even few days in background also it works..

it seems to be strange.. i need to know the reson is it with network problem.. or any issue..

but report is schuled and sucefuly completing in R/3 side. if we see the status of the job..

Regards

Vijay
