System copy

Quick answer

A careless system copy can send test transactions to real partners (via inherited RFC/interface config) or expose production data.

Key takeaways

  • A homogeneous copy keeps the same OS and database; a heterogeneous copy changes them (also called a migration, e.
  • After copying, the target must be adjusted so it does not behave like the source: rename the SID/logical system, reconfigure RFC…
  • Refreshing QAS/sandbox with realistic production data.
  • Watch out: Inherited interfaces sending test data to real partners.

Why system copies are done

  • Refreshing QAS/sandbox with realistic production data.
  • Building new systems in the landscape.
  • Creating temporary systems for projects or testing.

Homogeneous vs heterogeneous

A homogeneous copy keeps the same OS and database; a heterogeneous copy changes them (also called a migration, e.g. to HANA), which uses SWPM’s export/import (or DMO). Homogeneous copies can also use database-native backup/restore for speed.

Critical post-copy steps

After copying, the target must be adjusted so it does not behave like the source: rename the SID/logical system, reconfigure RFC destinations and interfaces, adjust the TMS, reset background jobs, and, importantly, scramble or protect sensitive production data copied into a non-production system.

Why care

A careless system copy can send test transactions to real partners (via inherited RFC/interface config) or expose production data. The post-copy checklist exists precisely to prevent these serious mistakes.

Common pitfalls

  • Inherited interfaces sending test data to real partners.
  • Unscrambled production data in a non-production system.
  • Forgetting logical-system/TMS adjustment after copy.

Frequently asked questions

What does the term System copy refer to in SAP?

A system copy duplicates an SAP system, for example refreshing QAS from PRD, or building a new sandbox. It is a routine but delicate Basis task with important post-copy steps to keep the landscape consistent.

What is connected to System copy in an SAP landscape?

A careless system copy can send test transactions to real partners (via inherited RFC/interface config) or expose production data.

What is another point to note about System copy?

A homogeneous copy keeps the same OS and database; a heterogeneous copy changes them (also called a migration, e.

What tends to go wrong with System copy?

Inherited interfaces sending test data to real partners. Unscrambled production data in a non-production system. Forgetting logical-system/TMS adjustment after copy.
