Article 43: What procurement proposals does MRP generate and how do I process them?
What procurement proposals can MRP create?
When MRP identifies a material shortage, it automatically generates procurement proposals - recommendations for specific actions to resolve the shortage.
What are the main types of procurement proposals?
Purchase Requisitions
When generated:
- Material has procurement type "F" (External)
- Vendor sourcing is the preferred method
- Lead time and cost favor external procurement
What information is included:
- Material number and description
- Required quantity to cover shortage
- Delivery date needed
- Suggested vendor (if source list exists)
- Cost center or account assignment
How to process:
- Review requirements in MD04 or MD05
- Verify quantities and delivery dates
- Convert to Purchase Order via ME57 or ME59
- Send to vendor for fulfillment
Planned Orders
When generated:
- Material has procurement type "E" (In-house)
- Internal production is preferred method
- Manufacturing capability exists
What information is included:
- Material to be produced
- Production quantity needed
- Start and finish dates
- BOM and routing references
- Resource requirements
How to process:
- Review production capacity and scheduling
- Firm the planned order if approved (MD11)
- Convert to production order (CO40)
- Release for production when ready
Transfer Requirements
When generated:
- Material sourced from another plant or storage location
- Special procurement key configured for transfers
- Stock available at source location
Processing steps:
- Verify source availability
- Create transfer order or stock transport order
- Coordinate logistics between locations
- Monitor transfer until receipt
How do I efficiently process multiple proposals?
Mass Processing Tools
Transaction ME57 (Convert PRs to POs):
- Bulk conversion of purchase requisitions
- Automatic vendor selection based on source determination
- Exception handling for complex cases
Transaction MD11 (Firming Planned Orders):
- Mass firming of planned orders
- Capacity checking integration
- Priority-based processing
Transaction MD15 (Collective Conversion):
- Mixed proposal types handled together
- Planner-specific workload management
- Exception reporting for failed conversions
What factors should I consider before converting?
Before Converting Purchase Requisitions:
Supplier Evaluation:
- Vendor capacity to deliver on time
- Price competitiveness and terms
- Quality capability and certifications
- Current workload and priority
Internal Considerations:
- Budget approval and authorization
- Delivery coordination with receiving
- Quality inspection requirements
- Payment terms alignment
Before Converting Planned Orders:
Production Feasibility:
- Manufacturing capacity availability
- Component availability from BOM
- Resource scheduling and conflicts
- Quality requirements and setup time
Strategic Alignment:
- Make vs buy economics
- Load balancing across work centers
- Inventory strategy and turnover goals
- Customer priority and delivery promises
What monitoring is needed after conversion?
Purchase Order Monitoring:
- Vendor confirmations and delivery updates
- Expediting for critical requirements
- Quality issues and corrective actions
- Invoice verification and payment
Production Order Monitoring:
- Material availability for production start
- Progress reporting and milestone tracking
- Quality control and testing results
- Goods receipt upon completion
