Distribution center replenishment planning from vendor to DC

Project overview

A retailer operating a central distribution center was struggling to keep core items available without creating excess inventory. Purchase decisions were often reactive, and buyers had limited visibility into which requirements had already been covered by open supply. The target state was a stable SAP S/4HANA Retail planning process in which merchandise requirements are reviewed at regular intervals, converted into controlled procurement documents, and then followed through goods receipt and invoice verification.

Business challenges

• Replenishment decisions were heavily dependent on manual follow-up and spreadsheet-based coordination.
• Buyers lacked one transparent sequence from requirement calculation to vendor purchase order creation.
• Late ordering caused avoidable shortages in the DC, while inconsistent follow-up sometimes resulted in duplicate or unbalanced procurement.
• Logistics and finance teams were not aligned on the handover between inbound execution and invoice verification.

SAP Retail solution design

• Implemented a regular merchandise requirements planning rhythm for the distribution center.
• Used SAP Retail to generate purchase requisitions from the planning run and convert approved demand into vendor purchase orders.
• Standardized inbound execution through goods receipt posting and warehouse putaway confirmation.
• Linked logistics completion to invoice verification and commercial follow-up so procurement and finance work from the same process backbone.

Expected business impact

• Created a more disciplined replenishment model for the DC.
• Improved visibility from demand signal to inbound execution.
• Reduced procurement firefighting and supported more reliable stock availability planning.
• Established a cleaner cross-functional handover between purchasing, warehouse and finance.

Recommended next steps

Recommended next steps include exception-based monitoring for late vendors, planning parameter tuning by merchandise category, and dashboarding for requisition aging and inbound reliability.
