From need to purchase order
Purchase requests, approvals, supplier selection, goods and service orders and outline agreements are scoped around your organisation. Approval limits reflect agreed responsibilities.
SAP MM: connect purchasing and inventory to the supplier invoice.
MM follows a purchase from the initial need through the order, goods receipt, inventory and supplier invoice. We help procurement, warehouse and accounts payable teams connect operational rules with SAP and their accounting effects.

01 · UNDERSTAND
Explain discrepancies before clearing them.
A blocked invoice can point to a missing receipt, an outdated price or an unsuitable tolerance. Reviewing the entire purchasing flow helps teams distinguish data issues from process and configuration issues.
- Align approvals with actual responsibilities.
- Reconcile physical, SAP and accounting stock.
- Understand price and quantity differences.
- Trace purchasing costs into finance and projects.
02 · DESIGN & DELIVER
Expertise grounded in how you work.
Goods receipts and inventory
Receipts, partial deliveries, supplier returns, physical inventory and valuation are examined together so physical movements and SAP records can be reconciled.
Invoice verification and reconciliation
We review purchase-order, receipt and invoice matching, tolerances and blocked invoices. Root causes in master data or rules guide corrective actions.
Finance and management accounting integration
Account determination, the goods-receipt/invoice-receipt clearing account (GR/IR) and cost-centre or project assignments connect MM with FI and CO.

USEFUL ANSWERS
Your questions.
Why are supplier invoices blocked?
Possible causes include incomplete orders, missing receipts, obsolete reference prices and unsuitable tolerances. A representative sample helps classify the causes before choosing corrective actions.
How can GR/IR be reconciled?
Review outstanding items and their origin, including receipts without invoices and invoices without receipts. Finance must approve the treatment, considering accounting policy and the SAP release.
Should MM and SD be considered together?
Yes when flows share inventory or cross company boundaries. The SD/MM overview explains those interfaces; this page focuses on purchasing and inventory.
Can suppliers and materials be migrated?
Within an agreed migration scope, master-data preparation, mapping and reconciliation precede loading. Data quality and acceptance controls are defined with the owners.
