What is SAP Purchase Requisition?
Definition
An SAP Purchase Requisition is an internal request in SAP used to identify a requirement for materials or services and initiate procurement activity. It records what is needed, the required quantity, delivery timing, and relevant accounting information. Unlike a purchase order, a Purchase Requisition generally represents an internal purchasing need rather than a formal commitment sent to a supplier.
The requisition creates a structured link between operational demand, purchasing controls, and financial planning. A well-managed requisition supports budget control, accurate cost allocation, and better visibility into expected spending before supplier commitments are finalized.
How SAP Purchase Requisition Works
The purchasing cycle typically begins with Purchase Requisition Creation. A requester enters the required material or service, quantity, delivery date, plant, purchasing group, and account assignment information. SAP assigns a unique Purchase Requisition Number that enables the request to be identified and monitored throughout its lifecycle.
During Purchase Requisition Submission, the request may be routed for review based on factors such as value, cost center, purchasing category, or organizational responsibility. Once the required authorization is completed, purchasing teams can use the approved requisition as a sourcing input or convert it into a purchase order.
The resulting purchase order establishes the external supplier commitment. Related activities, including purchase order approval and Purchase Order Dispatch Documentation Management, help maintain controlled documentation from internal demand through supplier communication.
Core Purchase Requisition Components
A requisition contains information that allows procurement and finance teams to understand both the operational requirement and its financial impact. Each Purchase Requisition Line Item can represent a separate material, service, delivery requirement, or accounting assignment.
Material or service details: Describe the item or activity being requested.
Quantity and delivery date: Define the volume required and expected timing.
Plant and purchasing group: Identify the responsible operational and procurement units.
Account assignment: Links spending to a cost center, internal order, asset, or project.
Source information: May identify a preferred supplier, contract, or purchasing arrangement.
Approval information: Records authorization requirements associated with the request.
These elements make the requisition more than a basic Purchase Requisition Form. They provide structured procurement data that supports financial oversight and consistent purchasing decisions.
Purchase Requisition Workflow and Status Tracking
The Purchase Requisition Workflow controls how a request moves from entry to authorization and purchasing action. Approval conditions can be configured around monetary thresholds, account assignments, purchasing groups, or other organizational criteria. This helps align procurement activity with delegated authority and internal spending policies.
Purchase Requisition Tracking provides visibility into the current stage of a request. The Purchase Requisition Status can indicate whether the requirement is awaiting approval, approved, assigned for sourcing, or associated with a subsequent purchasing document. This visibility helps requesters and purchasing teams coordinate expected procurement activity.
For finance teams, status visibility also improves understanding of planned expenditure. Although a requisition is not always an accounting posting, approved purchasing demand can contribute to cash flow forecasting and forward-looking spend analysis.
Financial and Procurement Importance
SAP Purchase Requisition data provides an early view of purchasing demand before a supplier commitment is formally established. Finance teams can review expected spending by cost center, project, material category, or organizational unit. Procurement teams can consolidate similar requirements and identify opportunities for strategic sourcing.
The Purchase Requisition Request also supports procurement compliance by documenting the origin and authorization of purchasing demand. This creates a traceable connection between the requester, approved requirement, purchasing action, and eventual supplier transaction.
In transaction or integration environments, purchasing commitments may also provide supporting information for expenditure analysis. However, concepts such as Working Capital Purchase Price Adjustment require separate transaction-specific calculations and should not be treated as direct purchase requisition measurements.
Best Practices for SAP Purchase Requisition Management
Effective requisition management depends on complete request data, clear authorization rules, and consistent monitoring. Organizations should standardize required fields so purchasing teams receive enough information to act without unnecessary clarification.
Use precise material and service descriptions for every request.
Assign accurate cost centers, projects, or other accounting objects.
Maintain clear approval thresholds based on purchasing authority.
Review open requisitions regularly to identify outdated demand.
Monitor conversion from requisitions to purchase orders.
Use status reporting to improve procurement planning and spend visibility.
These practices strengthen spend management and help finance teams connect planned purchasing requirements with budgets and expected cash requirements.
Summary
An SAP Purchase Requisition is an internal procurement document used to capture and authorize requirements for materials or services. It records detailed purchasing and accounting information, supports approval routing, and provides visibility into expected expenditure before a purchase order is issued. Through accurate requisition creation, status monitoring, and controlled conversion to purchasing documents, organizations can improve procurement governance, financial planning, and operational efficiency.
