SAP PM Interview Questions
1. What is SAP Plant Maintenance (PM) ?
SAP Plant Maintenance (PM) is a module within SAP ERP that supports the maintenance process by managing inspection, preventive maintenance, repair, and maintenance-related activities. It integrates with other SAP modules such as Materials Management (MM), Production Planning (PP), Controlling (CO), and Project System (PS).
2. What are the key components of SAP PM ?
Technical Objects: Includes equipment and functional locations.
Maintenance Planning: Strategies and schedules for preventive maintenance.
Maintenance Processing: Execution of maintenance tasks via maintenance orders.
Work Clearance Management (WCM): Ensures safety during maintenance.
Notifications: Records issues or defects.
3. What is a Maintenance Notification in SAP PM ?
A maintenance notification is used to inform about malfunctions or maintenance requirements. It helps initiate maintenance processes and track maintenance activities.
4. What is a Maintenance Order in SAP PM ?
A maintenance order is a document used to plan, schedule, and execute maintenance activities. It includes tasks, operations, material requirements, and costs.
5. What are the types of Maintenance in SAP PM ?
Corrective Maintenance: Actions performed after detecting a fault.
Preventive Maintenance: Regular maintenance to prevent failures.
Predictive Maintenance: Maintenance based on the condition and performance of equipment.
6. What is a Functional Location ?
A functional location is a hierarchical structure that identifies locations within a plant where equipment can be installed. It helps track and manage maintenance activities.
7. How is equipment managed in SAP PM ?
Equipment is managed through its master data, which includes technical specifications, classification, and history. Maintenance activities can be tracked based on equipment data.
8. What is the difference between Equipment and Functional Location ?
Equipment: Individual physical assets that can be moved.
Functional Location: Fixed locations within the plant.
9. How is preventive maintenance scheduled in SAP PM ?
Preventive maintenance is scheduled using maintenance plans, which define the maintenance strategy, cycle, and scheduling parameters.
10. What is a Task List in SAP PM ?
A task list is a predefined set of maintenance activities that can be used in maintenance orders or plans for consistent execution of tasks. Task lists can include operations, materials, spare parts, tools, and labor requirements. They help streamline maintenance processes by providing a standard set of instructions that reduce planning efforts and ensure consistency across similar maintenance tasks. Task lists can be general, specific to equipment, or linked to functional locations.
11. What is a Maintenance Plan ?
A maintenance plan defines when and how preventive maintenance tasks should be performed. It can be time-based, performance-based, or condition-based.
12. What is Work Clearance Management (WCM) ?
Work Clearance Management (WCM) is an essential component in SAP PM that ensures the safe execution of maintenance work. WCM manages permits for work, monitors hazardous energy isolation, and ensures compliance with safety regulations. It involves creating work permits, ensuring that safety checks are performed, and managing the lockout/tagout process to secure dangerous equipment before maintenance work begins. WCM ensures that maintenance work is carried out in a controlled and safe manner, reducing the risk of accidents.
13. What are the different types of task lists in SAP PM ?
General Task List: Can be used for various pieces of equipment or functional locations.
Equipment Task List: Specific to a particular piece of equipment.
Functional Location Task List: Specific to a particular functional location.
14. How is maintenance costing handled in SAP PM ?
Costs are captured in maintenance orders and can include labor, materials, and services. These costs can be settled to cost centers, internal orders, projects or assets.
15. How are spare parts managed in SAP PM ?
Spare parts are managed through integration with the MM module. Material master data is maintained, and stock levels are monitored.
16. What is a Breakdown Notification ?
A breakdown notification is raised when equipment fails unexpectedly, prompting corrective maintenance actions.
17. How is maintenance order settlement handled ?
Maintenance order costs are settled to appropriate cost objects, such as cost centers, internal orders or projects at the end of the maintenance process.
18. What is the role of measuring points and counters ?
Measuring points and counters are used to track operational parameters like hours, kilometers, or cycles, which can trigger maintenance activities.
19. How is reporting handled in SAP PM ?
SAP PM provides various reports for maintenance analysis, such as equipment history, maintenance cost reports, and notification status.
20. What is the role of Maintenance Notification Types ?
Notification types categorize maintenance notifications, such as malfunction reports, activity reports, or inspection reports.
21. How is integration handled in SAP PM ?
SAP PM integrates with MM, FI, CO, PP, and PS to facilitate procurement, costing, production maintenance requirements, and project-related maintenance activities.
22. What is a Service Notification ?
A service notification is created for customer service-related processes, including complaints or service requests.
23. How is capacity planning handled in SAP PM ?
Capacity planning ensures that resources (labor, equipment, and tools) are available for maintenance activities. It involves analyzing work center capacities, planning the availability of maintenance resources, and ensuring that scheduled maintenance activities do not exceed available capacity. This helps prevent resource bottlenecks and ensures that maintenance work is carried out efficiently without impacting production timelines. Integration with PP and PS modules ensures that capacity constraints are considered across related production and project activities.
24. What is the difference between corrective and preventive maintenance ?
Corrective Maintenance: Addressing issues after a failure occurs.
Preventive Maintenance: Regularly scheduled maintenance to avoid failures.
25. How is data migration handled in SAP PM ?
Data migration involves transferring equipment, functional locations, and historical data into SAP using tools like LSMW or BAPIs.
