RFC Error: Function module "/IWBEP/FM_MGW_READ

After transporting into our "next-system", we got the Error Message: "RFC Error: Function module "/IWBEP/FM_MGW_READ_ENTITYSET" not found", and according to this post written by Krishna (http://scn.sap.com/community/netweaver-gateway/blog/2013/08/09/frequent-problems-encountered-in-netweaver-gateway-service-development)

I done the checks mentioned:

Go to transaction /IWFND/MAINT_SERVICE

Here I an see my service points at the right destination.

In SPRO I go to the system alias, and I can see that:

"FOr Local App" is checked

"RFC Destination" is correct.

"Software Version" is "Default"

"System" and "ID" is correct.

Then I go to the "Manage RFC destinations" in SPRO.

I noted the RFC destination from above, and double click on the connection.

Make a connection test, and it went OK.

Then I tried the other parts, as mentioned in the article:

/IWFND/ERROR_LOG - just show me the same error

/IWFND/APPS_LOG - tells me that it is an RFC error

/IWBEP/ERROR_LOG + /IWBEP//VIEW_LOG does not tell me anything,as it is empty.

When I debug, I got into method: /IWCOR/IF_REST_HANDLER~HANDLE (/IWCOR/CL_DS_HDLR_ROOT)

I can see my mv_svc_resolution_type is equal to '3'

IF mv_svc_resolution_type = gc_svc_by_segment_1_and_2 AND lv_service_namespace IS INITIAL.

RAISE EXCEPTION TYPE /iwcor/cx_ds_not_found.

ENDIF.

Anyone who can help me?

Thanks,

Aikon
