Error when importing data from IBP to ECC using webservice

Hello experts,

I am new to HCI. My requirement is to transfer data from IBP to ECC.

I have created webservice in ECC and imported successfully in HCI.

http://Hostname:8000/sap/bc/srt/wsdl/srvc_22000B6C036A1ED984E2BFA807F65092/wsdl11/allinone/ws_policy/document?sap-client=800

Dataflow:

Validated without any errors but ended with the below error.

RUN-248005 |Data flow ibp_to_d01_task_DF_IBP_TO_D01_TEST2|Transform Target_Web_Service_Call-Function2
There is no response for the web service <ZbapiIbpToD01Test1>. Ensure that the network, web server, and service are running properly. Also ensure that the service client call time out is set properly.

I'm wondering if any of you had this issue before and could provide me with more solution approaches.

Thanks in advance
