Engineering Change Management (ECM) in SAP S/4HANA (transaction CC01/CC02) manages changes to objects like BOMs, routings, and materials with a structured process:
* To save multiple changes for an object(C): ECM allows multiple changes (e.g., to a BOM's components) to be grouped under one change number (field: Change Number in CS01). These changes are saved and applied together on a specified date (Valid From), ensuring coordinated updates across objects.
* To monitor document object changes(D): ECM tracks changes to objects (e.g., materials, BOMs) linked to a change number, providing an audit trail (transaction CC03, History tab). This monitors who changed what and when, supporting compliance and traceability.
To monitor document table changes(A) is vague-"document" likely means BOM or routing, but ECM focuses on object changes, not table-level monitoring (e.g., database logs).To enable integration into a sales order(B) is incorrect-ECM integrates with production or procurement, not directly with sales orders (VA01). This is per SAP's ECM functionality.
