Hi @JanNuaman-2253 ,
please take a look here on the "SAP on Azure Architecture Guide".
https://learn.microsoft.com/en-us/azure/architecture/reference-architectures/sap/sap-overview#scalability
There you will find a recommendation to use a different SAP vNet (hub-spoke topology).
In a lot of the SAP Architecture Guides from Microsoft you will find these kind of hub-spoke topologies
