Creating an equipment master record in SAP S/4HANA serves multiple purposes, particularly:
To perform and record maintenance tasks for certain parts of your technical system for long-term evaluation (B): Equipment master records are crucial for planning, executing, and documenting maintenance activities, enabling a detailed analysis of maintenance history and equipment performance over time.
To collect and evaluate technical data for an object over a long period of time (D): Equipment master records provide a centralized repository for all technical and historical data related to a piece of equipment, facilitating long-term tracking and analysis of equipment health, usage, and maintenance needs.
Reporting the usage time of an object at a functional location (A) is more directly related to the functional location master record, which represents the spatial or organizational structure in which the equipment operates.
Functionally representing the technical system structures at your company (C) is more closely related to the use of functional locations in SAP, which map the physical and organizational structure of a company's technical systems.
