I have few queries , to function this report what are the per-requisites we need to perform.

1. Do we need to setup any RFC connection for this communication ??

2. Is there any port to be opened ?

Please put all your thoughts here.

Really appreciate your inputs for this query.

Thanks

Pradeep.

Hi Pradeep,

I assume that ECC layer is on-premise and API created and managed by SAP API Management is on the cloud.

Please use SAP Cloud Connector to connect to your on-prem ECC system

Please refer blog Cloud Connector as a bridge connecting SAP API Management and On-Premise System
