How to connect to other VPC SAP instance having VPC Peering via Appflow ?

Set Up VPC Peering ==> IAM Role and Permissions (Create an IAM role that grants AppFlow permissions to access the necessary resources in both VPCs. ) ==> Set up an AppFlow flow (Define the source and destination connectors (such as SAP) ==> Network Configuration (Ensure that the security groups and network ACLs allow the necessary traffic between the peered VPCs.) ==> Test Connectivity.

For more details, I recommend checking the AWS documentation:

AWS AppFlow Documentation & AWS VPC Peering Documentation

I believe AWS AppFlow connections can be configured with or without PrivateLink, depending on your network architecture and security requirements. If you are using VPC peering and want to leverage PrivateLink, make sure that PrivateLink is enabled for AppFlow in both the source and destination VPCs.

• Please see this : https://docs.aws.amazon.com/appflow/latest/userguide/private-flows.html

Also, if you're connecting to a private SAP instance in another VPC, you generally use the private IP address or DNS hostname of the SAP instance. The URL would typically be something like sap://<private-ip-or-hostname>:<port>.

Are these 2 VPCs in same account or different account?
