Simplification Items and the Simplification Item Check

Keep this: job aid

Simplification item and SI check card

• Item = documented, potentially incompatible change; read its business impact note (current version).
• Know the big data model moves: MATDOC, SD status in VBAK/VBAP, PRCD_ELEMENTS, ACDOCA, business partner.
• Find relevant items with Readiness Check (effort ranking, activities, follow-ups in SAP Cloud ALM) and the SI check.
• SI check: /SDF/RC_START_CHECK; notes 2399707 (framework) and 2502552 (check classes via TCI); client 000, right target.
• Return codes: 0 OK, 4 read, 7 exempt or fix (documented), 8/12 fix before conversion; SUM stops for 12 first, 8+ before downtime.
• Freeze notes and download the local catalog before converting DEV; reuse for QAS and PRD.
• Clear 8/12 in EP1 before the Mock 1 copy; re-run in every cycle and in the final week.
• CVI pre-project: CVI_FS_CHECK_CUSTOMIZING, then MDS_LOAD_COCKPIT, then the detailed SI check.
• Log per item: note version, impact, action and phase, owner, test.
• Test every item with business impact: change tests plus sameness tests (DTV, CVI link table counts).
