🔹Reason-

🔹1)Hardware costs-First Installing separate SAP systems requires more servers, storage, and licenses, which is very expensive. By using multiple clients in one system, companies can share the same hardware.This costs helps organizations save a lot of money while still keeping data separate.

🔹2)Maintenance effort-Maintaining many SAP systems means applying updates, patches, and fixes multiple times.With multiple clients, maintenance is done once for the entire system.This reduces workload for the IT team and minimizes system downtime.

🔹3)Time for system administration-Also Managing users, security, and backups in many systems takes a lot of time.Multiple clients allow administrators to manage everything from one place.This saves time and makes system control faster and more efficient.
