What SAP objects are typically updated by an ECO in the ECMS process?

• A. BOMs, Routings, Material Master attributes, Classification/Characteristics, PRTs, document attachments, and possibly master data in procurement or quality.
• B. BOMs only.
• C. Routing only.
• D. PP-PI characteristics only.

Answer: (A)

An ECO in ECMS is intended to propagate engineering changes across the full set of product and production data, not just a single area. When a change is approved, it updates the structures and data that define how a product is built and managed in SAP, so everything stays in sync with the new design.

BOMs and routings are updated because the engineering change often alters what goes into the product and how it is produced. If components change or a newer process is required, the BOM must reflect new components, quantities, or revisions, and the routing must reflect updated steps, operations, or work centers.

Material Master attributes are updated to keep material specifications, procurement data, planning information, and other key attributes current with the new design. Classification/Characteristics are refreshed to ensure the material’s classifications and attribute values align with the revised specs, enabling correct variant handling and searchability.

Production Resources/Tools (PRTs) may be updated to reflect changes in tooling or equipment required for the new process. Document attachments are added or revised to attach updated drawings, specifications, or test methods that accompany the change.

Finally, ECOs can involve master data in procurement or quality to align sourcing information, vendor data, or inspection characteristics with the updated material and process requirements.

That broad set of touched objects explains why the comprehensive option is correct, rather than limiting changes to just BOMs, just routings, or only a subset like PP-PI characteristics.
