How do I ensure my seasonal seed demand planning with a supply planning platform is compliant with ERP controls?

To keep seasonal seed demand planning compliant with ERP controls, treat the supply planning platform as a planning engine and the ERP as the system of record for master data, approvals, inventory, and financial controls.

Practical checklist

1. Align master data and governance

• Use ERP master data as the source of truth for:
  • Item/SKU definitions
  • UoM conversions
  • Locations/warehouses
  • Customer/channel hierarchies
  • Lead times, safety stock rules, MOQ/pack sizes
• Put change control around any planning parameter changes.
• Restrict who can create or edit planning assumptions.

2. Define approval workflows

• Require approvals for:
  • Seasonal demand assumptions
  • Forecast overrides
  • Production/purchase plan changes
  • Exception quantities above thresholds
• Keep role-based approval matrices aligned with ERP authorization rules.

3. Maintain a full audit trail

• Log every change to:
  • Forecasts
  • Demand plans
  • Supply recommendations
  • Manual overrides
  • Scenario selections
• Capture:
  • Who changed it
  • What was changed
  • When it changed
  • Why it changed
• Ensure the platform can produce audit evidence for internal and external audits.

4. Separate planning from execution

• Use the planning platform for what-if analysis and recommendations.
• Push only approved plans back to ERP for execution.
• Prevent planners from directly posting inventory, purchasing, or financial transactions in the planning tool.

5. Reconcile with ERP regularly

• Reconcile on a set cadence:
  • Forecast vs actual demand
  • Planned supply vs open POs/work orders
  • Inventory balances
  • Seasonal allocations by region/customer
• Investigate and document variances beyond tolerance.

6. Control integrations

• Use controlled interfaces between systems:
  • Defined mapping tables
  • Validation rules
  • Error handling and exception queues
• Monitor integration jobs and failed transactions.
• Reconcile interface records to ERP postings.

7. Enforce segregation of duties

• A single user should not be able to:
  • Change assumptions
  • Approve the plan
  • Execute supply orders
• Separate planner, approver, and ERP execution roles.

8. Document seasonal business rules

For seed planning, document rules for:

• Planting windows and region-specific seasonality
• Shelf-life or viability constraints
• Lot/batch traceability
• Regulatory or phytosanitary requirements
• Allocations under constrained supply
• Pack/label compliance by market

9. Control scenario and version management

• Use named versions such as:
  • Baseline
  • Optimistic
  • Approved seasonal plan
  • Locked execution plan
• Lock the approved version before execution.
• Keep version history for audit purposes.

10. Validate user access and security

• Use ERP-aligned authentication and authorization:
  • SSO if possible
  • Least-privilege access
  • Periodic access reviews
  • MFA for privileged users
• Remove access promptly when roles change.

Compliance evidence to keep

• Forecast approval records
• Master data change logs
• Exception reports and resolution notes
• Interface reconciliation reports
• Access review results
• Plan version history
• Audit trails for overrides and approvals

Best practice operating model

A good control model is:

1. Plan in the supply planning platform
2. Review and approve via workflow
3. Publish approved plan to ERP
4. Execute only in ERP
5. Reconcile actuals back to planning
6. Audit changes and exceptions regularly
