Fiori Apps for Procurement: Top 10 Every MM Consultant Must Know

For decades, SAP consultants lived their professional lives navigating a maze of obscure transaction codes inside the classic SAP GUI. ME21N, MIGO, MIRO, and MD04 were the unquestioned pillars of the Materials Management (MM) module. This landscape changed forever with the introduction of SAP S/4HANA and the revolutionary SAP Fiori User Experience (UX).

Fiori isn't just a new coat of paint over the old transaction codes; it fundamentally re-imagines how business users interact with Enterprise Resource Planning software. It shifts the paradigm from "transactional data entry" to "role based, actionable insights." For an SAP MM functional consultant in 2026, fluency in Fiori is no longer a "nice to have" skill it is an absolute mandatory requirement for survival in the marketplace.

This article curates the top 10 Procurement and Inventory Management Fiori applications every serious SAP practitioner must know, understand, and implement for their clients.

The Strategic Shift from GUI to Fiori

The classic SAP GUI forced users to memorize data models. A buyer had to run three different background reports just to figure out which Purchase Requisitions urgently needed conversion into Purchase Orders. Fiori solves this by utilizing Embedded Analytics and Smart Business Dashboards.

When a buyer logs into their Fiori Launchpad, they are instantly presented with dynamic tiles. A tile might simply state: "Purchase Requisitions Overdue: 14" in bright red text. They click the tile, and the system automatically filters the exact 14 requisitions they need to work on immediately, providing a visual chart on the side to filter by vendor or specific plant. This "insight to action" design drastically reduces training time for end users and drastically increases operational efficiency.

The Top 10 Procurement Fiori Apps

1. Manage Purchase Requisitions (Professional and Employee)

Replaces: ME51N, ME52N, ME5A

This is arguably the most widely used P2P app across any enterprise. SAP provides a simplified "Employee" version for casual users requesting office supplies, mimicking an Amazon like shopping cart experience utilizing internal catalogs. The "Professional" version allows hardened buyers to handle complex limit items, service hierarchies, and advanced account assignments with far fewer clicks than the classic GUI.

2. Manage Purchase Orders

Replaces: ME21N, ME22N, ME2N

The absolute workhorse of the procurement department. This app provides a visually stunning list report showing the exact status of every PO (In Approval, Sent to Vendor, Goods Received, Invoiced). Instead of diving into line item details to see if a box arrived, the app prominently displays a "Delivery Status" progress bar directly on the overview screen for instant visibility.

3. Monitor Material Coverage (Net and Individual Segments)

Replaces: The legendary MD04 (Stock/Requirements List)

This is the holy grail for Material Planners. While MD04 was a static grid of numbers, the Fiori Monitor Material Coverage app introduces advanced color coding and interactive charts. A planner can instantly see a predicted stock shortage next Thursday, click the specific raw material, and seamlessly generate an emergency Purchase Order or Stock Transport Order from a neighboring plant directly within the same screen, without opening a new tab.

4. Post Goods Movement

Replaces: MIGO

Simplifying the dreaded complexity of MIGO, the Post Goods Movement app uses a clean, intuitive, step by step interface. It drastically improves the user experience for warehouse clerks performing Goods Receipts against Purchase Orders, issuing stock to cost centers, or handling standard transfer postings.

5. Create Supplier Invoice

Replaces: MIRO

Accounts Payable clerks benefit immensely from this app. It leverages embedded AI and Optical Character Recognition (OCR) integration far better than the old GUI. The system intuitively suggests PO matches based on intelligent algorithms, highlighting exactly where price or quantity variances exist in bright, unavoidable colors, accelerating the invoice clearing process.

6. Manage Source Lists

Replaces: ME01

A beautifully designed tool for strategic sourcing managers. It allows users to quickly block underperforming vendors globally or fix preferred suppliers for specific materials using a highly responsive, modern table view that supports complex excel like filtering locally in the browser.

7. Evaluate Suppliers

Replaces: ME61, ME6B

Vendor Evaluation in ECC was a painful, highly technical setup. S/4HANA revolutionizes this with standard Fiori KPIs. The Evaluate Suppliers app visually charts vendor performance over time across standard metrics like Price Variance, Delivery Reliability, and Quality Rejection Rates. A CPO (Chief Procurement Officer) can pull this app up on an iPad during a vendor negotiation meeting and show the supplier exactly where they are failing.

8. Monitor Purchase Order Items

Replaces: Custom ABAP ALV Reports

This is an analytical list page (ALP). It is specifically designed to identify friction in the supply chain. A buyer can easily filter for "PO items older than 30 days with 0% Goods Receipt" to proactively locate lost shipments or unresponsive suppliers before the manufacturing line runs out of components.

9. Manage Purchasing Info Records

Replaces: ME11, ME12

Maintaining complex pricing conditions (gross price, freight charges, special discounts) was always tedious. The Fiori equivalent vastly simplifies the interface, clearly dividing general vendor data from highly specific plant level pricing conditions with elegant tab navigation.

10. Overdue Purchase Order Items

Replaces: ME2A

A pure, focused, operational dashboard. It does one thing perfectly: it screams at the buyer about what is late. It provides immediate actionable insights, allowing the buyer to select multiple overdue PO lines and send an automated, structured follow up email to the vendor directly from the Fiori interface.

Implementation Best Practices for Consultants

When deploying Fiori for a client's procurement department, avoid the most common mistake: "Lift and Shift". Do not simply turn on the Fiori equivalent of ME21N and tell the users the project is finished.

Role-Based Design

Fiori is strictly role based. An Accounts Payable clerk should never see the Monitor Material Coverage tile on their launchpad, just as a Warehouse Worker should never see the Create Supplier Invoice tile. Work intimately with the business during blueprinting to define exact Business Roles (e.g., Strategic Buyer, Operational Purchaser, Inventory Manager) and assign only the exact apps, catalogs, and groups necessary for those specific daily tasks.

Leverage the Extensibility Framework

Inevitably, a client will demand a custom field. In the old GUI, this meant hiring an ABAP developer, creating an append structure on table EKKO, designing a screen exit, and writing complex logic in BAdIs (Business Add Ins). In S/4HANA, a functional consultant can utilize the Custom Fields and Logic Fiori app to add a new field to standard tables, publish the field directly to the Manage Purchase Orders UI, and include it in OData endpoints without writing a single line of traditional ABAP code.
