We are running SRM 7.0 SP 08.
I have set up the external web services to access multiple external product catalogs to create shopping carts. These individual catalogs work fine for SC creation. (BTW, we removed the parameter for HOOK_URL as it seems to be not required starting SRM7).
However, when we are trying to run "cross catalog search", either from SC creation wizard or from normal SC creation screen, the popup window would appear with search in progress, but always return no result with detail message: "ICM_HTTP_CONNECTION_FAILED" for all catalogs.
I have debugged the scenario, and the error seems to be from FM /SAPSRM/PDO_CCS_BCKGRSEARCH, which is called in a background task. The statement that got the error is the following, with return code 1.
CALL METHOD lv_res_client->receive EXCEPTIONS http_communication_failure = 1 http_invalid_state = 2 http_processing_failed = 3 OTHERS = 4.
Could you shed some light as to what might have been the problem?
Thanks for your help.
