Selective Data Transition Concepts

Keep this: job aid

Selective data transition fit card

• Three paths: new implementation, system conversion, selective data transition in between.
• SDT selects four layers independently: ABAP repository, configuration, master data, transaction data.
• Shell conversion: copy production without business data, convert it, then transfer data. Best when most processes are reused.
• Mix and match: install new, bring selected configuration and code. Best when most of the solution is redesigned.
• Scope by organization, application, master data filter and time slice; write down every decision and its owner.
• Time slices need document-chain rules and correct opening balances.
• Shell conversion means retrofit: log and retest every production change until cutover.
• Reconcile against the selection: everything inside arrived, nothing outside arrived, all consistent.
• Test that history is usable: reports, document flow, returns and credit memos on transferred documents.
• Public Edition moves are normally new implementations; confirm before planning SDT.
