Int4 Suite installation options
Add-on Installation Options
There are two options for installing the Int4 Suite Add-on based on client or project preferences:
1. Centralized installation on SAP Solution Manager or other SAP ABAP Application Server
In this scenario, the Int4 Suite Add-on is installed on SAP Solution Manager or a separate SAP ABAP Application Server. It stores and manages test cases for all non-production environments.

Such an installation model requires one of the following:
an Int4 Suite function module, created in customer space by copying and pasting the source code.
full Int4 Suite Add-on deployment on each SAP ECC/S4HANA backend.
If only the function modules are deployed, test types like IDocs, AIF and Proxies will not work.
2. Decentralized installation directly on SAP ECC/S4HANA Backend
In this scenario Int4 Suite Add-on is installed on the central SAP ECC instance.
