SAP ECC and Seko
Integration Agency & Consultants
When stock discrepancies between SAP financial values and Seko physical counts begin causing audit failures or shipment delays, the integration architecture has usually buckled under scale. At high volume, reliance on manual stock reconciliation creates a financial trust boundary that slows the business down. We bridge the gap between SAP ECC message types and Seko’s logistics API, ensuring inventory truth is maintained without forcing expensive customisations on the warehouse side. This architecture is designed for operators who need to eliminate stuck IDocs and maintain an auditable match across the supply chain.

Our consulting services, including comprehensive system audits, identify inefficiencies and integration gaps, enabling your team to take decisive action. By addressing these issues, we help your tech ecosystems, including SAP ECC and Seko, run smoothly, ensuring your ERP and WMS/3PL systems deliver a great customer experience. Our expertise ensures your technology infrastructure supports your business goals effectively.
Solution Design
This design establishes SAP ECC as the master for SKU data and purchase orders, while Seko owns warehouse execution. A critical architectural choice involves mapping SAP Plant and Storage Location codes directly to Seko’s logical facility zones. We prioritise transactional integrity for the financial close by sequencing fulfilment confirmations to trigger billing in SAP promptly. However, we typically treat inventory updates from Seko as a scheduled batch rather than real-time. This trade-off acknowledges that while intra-day stock figures may have a slight lag, the stability of the SAP material master is protected from excessive IDoc load. The result is a controlled operating model where the warehouse executes with speed, but finance retains an auditable three-way match and trust in the SAP stock valuation.
Managing data flow and record ownership
Data integrity relies on a strict flow where SAP ECC remains the system of record for SKUs and inbound purchase orders. Once SAP releases an outbound delivery, the integration translates internal SAP codes into Seko-compliant fulfilment requests. Fulfilment confirmations then flow back from Seko to SAP to trigger billing and inventory reduction. We embed monitoring at the connection layer to detect failed data transfers before they manifest as customer service issues, ensuring every physical movement has a corresponding financial entry.
Orchestrating secure data transfer via IPaaS
Cogent2 leverages IPaaS to integrate SAP ECC and Seko with ERP and WMS/3PL systems securely. This approach ensures SAP ECC and Seko data flows efficiently between ERP and WMS/3PL platforms. IPaaS platforms with ISO 27001 and SOC 2 compliance and above provide robust security, safeguarding sensitive information. The benefits include streamlined operations, reduced manual errors, and enhanced data accuracy, all while maintaining high security standards.
Surfacing inventory drift and mapping errors
Dashboards that only show 'up or down' status are insufficient for SAP and Seko operations. Hidden issues, like SAP storage locations not being correctly mapped to Seko facility zones, lead to inventory drift that quietly compounds over weeks. Our platform surfaces these exceptions early, highlighting specific data transfer failures or mapping mismatches that stop orders from reaching the warehouse. This visibility allows finance and operations to identify why a physical shipment hasn't triggered an SAP update, preventing month-end reconciliation issues.
Handing over daily stock reconciliation tasks
Finance, operations, and ecommerce teams must move from manual workarounds to owning the logic between SAP ECC and Seko. Handover starts with the operating model: finance learns to reconcile SAP stock value against Seko physical counts, while operations manages the ownership of facility mapping. We provide operational documentation that details daily stock reconciliation checks and how to interpret alerts when a data transfer fails. This documentation is written for the people running the business, not as a technical reference. It ensures your team knows exactly who owns each exception type, from SKU mismatches to fulfilment delays, before we step back.
Maintaining ledger integrity and shipment flow
Post-launch support is focused on maintaining the integrity of the SAP financial ledger and warehouse execution. We monitor the integration for data transfer failures and Seko exceptions, ensuring issues are surfaced and prioritised for the appropriate team. Our escalation process is designed for high-volume retail, where delays in stock sync can cause shipment backlogs. We take ongoing operational ownership of the connection, allowing your internal teams to focus on fulfilment rather than troubleshooting data transfers.
Common failures
Locked delivery documents and stuck confirmations Shipment confirmations from Seko commonly fail to post in SAP ECC if the delivery document is locked by a background Post Goods Issue job or an open user session. This creates a situation where goods have left the building, but the ERP remains unupdated. This delay prevents billing and creates reconciliation work that must be cleared manually before the month-end close.
Unmapped SKU substitutions at the pick face A failure occurs when SAP IDocs fail to post because Seko's system sends back a SKU that was substituted at the pick face without a corresponding update to the SAP Delivery document. This results in orphaned shipment records and requires manual intervention to realign the outbound delivery with the physical reality of the parcel.
Reference mismatches in dropship and returns Using SAP Purchase Order numbers as the identifier for Seko shipments in dropship scenarios often prevents the warehouse from processing returns against the original consumer Sales Order. This leads to warehouse teams receiving stock they cannot identify, delaying customer refunds and causing ambiguity between sales records and physical returns.
Frequently asked questions
How does this integration handle our rigid SAP IDoc formats without forcing custom work on Seko's side?
The integration uses a translation layer to convert SAP ECC's IDoc messages, such as ORDERS05 for sales orders, into the modern API structure Seko requires. This prevents costly custom development by handling field mapping and logic translation before the data reaches Seko. This ensures that every fulfilment request sent from SAP is in a format Seko can immediately process.
How do you prevent 'stuck' orders caused by mismatches between SAP stock locations and the physical warehouse?
We establish a definitive mapping between SAP ECC Plant and Storage Location codes and their corresponding logical zones in Seko's warehouse. This is a common failure point; without a clear mapping, outbound delivery IDocs from SAP will fail because Seko cannot identify the stock's physical location. This proactive mapping ensures that fulfilment work is never held up by location ambiguity.
Which system owns inventory data, and how are stock discrepancies between SAP and Seko resolved?
In this operating model, SAP ECC remains the financial source of truth for inventory value, while Seko's system is the master for the physical, available-to-ship count. The integration transmits stock adjustment messages from Seko back to SAP ECC to update inventory levels. This regular synchronisation ensures physical cycle counts in the warehouse are correctly reflected in SAP's financial records, which is critical for an accurate month-end close.
Our SKUs in SAP are padded with leading zeros. Will this cause order failures with Seko?
Yes, this is a frequent cause of integration failure, as SAP ECC often generates a padded SKU like '000012345' that will not match the '12345' SKU in Seko's system. The integration must include transformation logic to strip these leading zeros from the item code in the outbound IDoc. This ensures the SKU on the fulfilment request matches Seko's item record, preventing order rejection.
How does the integration data support our finance team's three-way match process?
The data flow is designed to ensure financial integrity from start to finish. Fulfilment confirmations from Seko, containing shipped quantities, are sent back to SAP ECC to create the Goods Issue. This allows your finance team to confidently match the original Purchase Order, the Goods Issue record in SAP, and the supplier's invoice, creating a verifiable audit trail for every dispatched order.
What happens if SAP sends a partial shipment update? Can Seko's system handle it?
This can cause significant issues if not handled correctly, as many logistics platforms cannot process partial shipment IDocs (DESADV) from SAP ECC. The integration must be configured to either hold the order until it can be fully allocated or to translate the single SAP partial shipment into a format Seko understands. Without this, you risk creating orphaned stock allocations in SAP that do not reflect the physical reality in the warehouse.
