In an SAP implementation project, which of the following activities belong primarily to the SAP MM (Materials Management) module implementation?

Introduction / Context:
SAP MM (Materials Management) is a core module in SAP ERP that supports procurement and inventory functions. During an SAP implementation, different functional modules focus on different business areas. Understanding which activities belong to MM helps candidates show that they can map business processes to the correct SAP components.

Given Data / Assumptions:

• SAP MM handles purchasing, inventory management, and material valuation.
• MM works closely with FI (Financial Accounting) for postings related to goods receipts and invoices.
• HR, marketing, and network infrastructure are handled by other modules or systems.
• We want the option that lists typical SAP MM implementation tasks.

Concept / Approach:
Key SAP MM implementation activities include defining organizational structures for purchasing and inventory, configuring material master and vendor master records, setting up purchasing document types, pricing procedures, and stock management processes, and integrating MM with FI for automatic postings. HR and payroll tasks belong to SAP HCM, web storefront and SEO tasks to SAP Commerce or external systems, and network configuration tasks to IT infrastructure, not MM.

Step-by-Step Solution:
1. Identify MM-specific tasks: material master configuration, vendor master setup, purchasing organization structure, inventory management settings, and MM–FI integration.2. Option A lists configuring material master and vendor master, defining purchasing and inventory processes, and integrating with FI for goods receipts and invoice verification. These are clearly MM-related activities.3. Option B describes payroll and time evaluation, which are HR/HCM responsibilities, not MM.4. Option C lists marketing and SEO tasks that fall outside SAP MM and even outside ERP in many cases.5. Option D mentions network configuration and firewall policies, which are infrastructure tasks, not part of MM module implementation.6. Therefore, Option A correctly describes activities in SAP MM implementation.

Verification / Alternative check:
SAP MM implementation guides and project blueprints emphasise tasks such as configuring purchasing groups, plants, storage locations, movement types, material types, and valuation classes. They also cover integration points like automatic account determination that posts accounting entries in FI when goods are received or invoices are posted. These topics match the activities in Option A and not the activities in the other options.

Why Other Options Are Wrong:
Option B is wrong because payroll and time management belong to SAP HCM, not MM.Option C is wrong because web marketing and SEO are not MM configuration tasks.Option D is wrong because network and firewall management are IT infrastructure responsibilities unrelated to SAP MM configuration.

Common Pitfalls:
In interviews, some candidates speak too generally about SAP implementation and fail to associate specific tasks with the correct module. Another pitfall is overlooking the important integration between MM and FI, which is a key part of making sure financial postings reflect goods movements. Knowing the typical MM activities strengthens your ability to explain your role in implementation projects.

Final Answer:
Configuring material master and vendor master, defining purchasing and inventory processes, and integrating with FI for goods receipts and invoice verification.
