ECC to SAP S/4HANA manufacturing change card

• Find your items: Readiness Check and SI check on production data, then read each business impact note.
• MRP Live (MD01N): no MRP lists, no creation indicators, no MRP type VV; restrictions in SAP Note 1914010.
• Storage location MRP → MRP areas (ND for excluded, VB for separately planned); run MRP_AREA_STORAGE_LOC_MIGRATION.
• Production versions are mandatory; CS_BOM_PRODVER_MIGRATION / ...02 can create them.
• Planning file: new table; set up with PPH_SETUP_MRPRECORDS.
• Compatibility scope (MRP lists, forecast-based planning): limited rights; check SAP Note 2269324.
• Embedded PP/DS: finite planning for critical materials; Enhanced LoB function, confirm licensing.
• Custom code: MRP BAdIs to AMDP; MRP-list reports go stale; ATC does not find everything.
• Regression: MRP comparison on frozen identical data; costing on a reference order; DTV for before/after.
• Sign-off: differences explained, values reconciled, production versions and MRP areas complete.
