SAP Functional Consultant (MM / P2P with FICO)

Position Overview:

This role involves defining how a third-party digital procurement marketplace fits into an enterprise SAP

procure-to-pay (P2P) landscape. The SAP Functional Consultant owns requirements, process design and

data mapping for vendor, catalogue, requisition, budget, PO, GR and invoice flows. The consultant acts as

the bridge between client business teams, the marketplace product team and SAP technical/integration

consultants, working alongside an SAP Technical / Integration Consultant. The role requires strong

client-facing communication, the ability to challenge assumptions and drive decisions, and hands-on

expertise in SAP MM, FICO integration, and ALE/IDoc/EDI-based data exchange.

Key Responsibilities:

• Run discovery workshops with procurement, finance and IT stakeholders to confirm the current SAP

landscape, version (S/4HANA or ECC) and process variants

• Design the end-to-end P2P flow across the marketplace and SAP: purchase requisition, PO, service entry

and acceptance, goods receipt, invoice and payment

• Define vendor onboarding and master data rules: sync with the Supplier Self Service (SUS) portal, vendor

approval, suspension and deactivation via vendor master blocks

• Specify catalogue and contract-price handling, including extraction of historical PO and contract prices for

price benchmarking

• Design budget and account assignment controls: charge codes, GL codes, cost objects and budget

availability checks against the budget system (ERMS) or SAP FICO before PO approval

• Specify 3-way match (PO, GR, invoice) and GR-before-invoice controls, including tolerances, blocks and

exception handling

• Establish source-of-truth ownership for vendor, material, service and plant master data and for budgets
• Design the ALE/IDoc and EDI data exchange from a functional standpoint: distribution models, message

types (e.g. CREMAS, MATMAS, ORDERS, ORDCHG, DESADV, INVOIC), filtering rules, partner-specific

requirements and field mappings for master and transactional data between SAP systems and with

non-SAP systems

• Monitor and troubleshoot IDoc processing (WE02/WE05, BD87): analyse failed or stuck IDocs, trace root

cause to data or configuration, coordinate reprocessing and define business exception-handling

procedures

• Write functional specifications, data mapping documents and interface field-level requirements for the

technical team

• Define multi-currency, pricing and audit-trail requirements so marketplace transactions reconcile with

SAP

• Prepare test scenarios, lead SIT and UAT with business users, and support cutover and hypercare

Required Skills:

• 7+ years of experience
• Bachelor's degree in engineering, commerce, finance or a related field
• 7+ years of SAP MM functional experience with at least 2 full-cycle implementations or major P2P rollouts
• Strong knowledge of P2P configuration: purchasing documents, release strategies, GR/IR, service entry

sheets, invoice verification (MIRO) and payment blocks

• Working knowledge of SAP FICO integration: GL accounts, cost centres, internal orders/WBS, account

determination and budget/funds checks

• Hands-on ALE/IDoc functional experience: designing, configuring, monitoring and troubleshooting the

exchange of master and transactional data between SAP systems (ALE) and between SAP and non-SAP

systems (EDI)

• Experience integrating SAP with external procurement platforms, e-catalogues or punch-out (OCI/cXML)

solutions

• Proven ability to write clear functional specs and data mappings for IDoc, BAPI or API-based interfaces
• Strong vendor, material and service master data management experience
