Hi to all,

    Generally, In ERP we have 3 layer architecture

    If we are using ERP on HANA or Suite on HANA we will still have 3 layer architecture and application layer sits in application server

    But we can also utilize the application server inbuilt in HANA and can have 2 tier architecture

    Check my blog for different scenarios related to HANA Security showing 3 tier and 2 tier architecture:
