# Delfoi Planner with SAP S/4HANA: finite scheduling for production orders > Source: https://netray.co/stack/delfoi-planner-sap-s4hana-finite-scheduling > Publisher: Netray (netray.co), AI and integration engineering for ERP and manufacturing systems. > Section: ERP Stack ## Short answer Delfoi Planner for SAP S/4HANA is a finite scheduling add-on listed on the SAP site. Planners work in a drag-and-drop Gantt, and revised plan dates and routings are sent back into S/4HANA. It also lists support for S/4HANA Cloud Public Edition, but this page focuses on the on-premise case. ## Erp SAP S/4HANA ## Erp Key sap-s4hana ## On Prem true ## Product Delfoi Planner for SAP S/4HANA ## Vendor Delfoi Oy ## Category APS ## Integration **Method:** SAP Store extension and add-on **Detail:** The listing describes an add-on that reads orders, routings, work centers and capacities from S/4HANA and writes back revised dates and routings. The exact transport mechanism (released APIs, OData or RFC) depends on the edition and version, so confirm it with Delfoi for your release. **Method:** Optimisation engine outside the ERP core **Detail:** Scheduling runs in the planner so that MRP and capacity logic are not stretched. The ERP stays the system of record for orders, and the planner's output is a schedule that updates order dates. ## Data Flows **From:** S/4HANA **To:** Delfoi Planner **Data:** Planned and production orders, routings, work centers, capacities and calendars **Trigger:** Scheduled sync or planner refresh **From:** Delfoi Planner **To:** S/4HANA **Data:** Revised start and finish dates, sequence and routing changes **Trigger:** Planner publishes a schedule **From:** S/4HANA **To:** Delfoi Planner **Data:** Confirmations, order status changes and material availability **Trigger:** Shop floor confirmation or order release ## Setup ### Scope the scheduling problem **Detail:** Pick the plants and work centers with real finite-capacity constraints, such as shared machines, tooling and setups. ### Clean the master data **Detail:** Fix routing times, work center capacities and calendars in S/4HANA first, because the planner will schedule exactly what the data says. ### Install and connect **Detail:** Deploy the planner per Delfoi's guide and connect it to S/4HANA with a technical user limited to the objects it reads and writes. ### Model constraints **Detail:** Configure setup matrices, parallel resources, shift patterns and planning rules in the planner. ### Run in shadow mode **Detail:** Compare planner schedules with what the plant actually ran for a few weeks before writing dates back. ### Define write-back rules **Detail:** Decide which orders the planner may reschedule, how firm orders are frozen and who can publish. ### Train planners **Detail:** Teach planners when to override and how to record the reason so changes stay explainable. ## Pitfalls - Optimistic routing times, which produce schedules the shop floor cannot meet. - Conflicts between planner dates and MRP regeneration that overwrite each other. - Orders already released or partially confirmed being moved without a freeze rule. - Calendar and shift mismatches between S/4HANA factory calendars and the planner model. - Missing material availability checks, so a feasible Gantt depends on parts that are not there. - Upgrades that change released interfaces and break the write-back until the add-on is updated. ## Ai Layer ### Schedule versus actual explainer **Description:** Read planner output and S/4HANA confirmations to explain in plain language why orders slipped, such as a long setup, a late component or a routing time that is too short. ### Routing time review **Description:** Compare routing standards with confirmed times and draft a list of operations where the data is consistently off, for a planner to approve before changing anything. ### Exception summary for the morning meeting **Description:** Summarise orders at risk, shortages and overloaded work centers across both systems, with each statement tied to a record. ## Alternatives - Native S/4HANA production planning (PP/DS where licensed, or capacity leveling) may be enough for simple, low-mix plants. - A spreadsheet or Gantt tool outside the ERP for a single bottleneck resource, if you do not need write-back. - A full MES with scheduling if shop-floor data capture is the larger gap. ## Faq ### Does Delfoi Planner replace MRP? **Answer:** No. MRP still calculates requirements and creates planned orders. The planner sequences and schedules those orders against finite capacity, then sends the revised dates back. Decide clearly which system owns dates after each MRP run. ### Does it work with both S/4HANA on-premise and cloud? **Answer:** The listing mentions S/4HANA and the Cloud Public Edition. The connection details differ by edition, so ask Delfoi which interfaces they use for your release before planning the project. ### What data quality does finite scheduling need? **Answer:** Accurate routing times, work center capacities, calendars and setup data. A finite scheduler exposes bad data quickly, so plan a data cleanup before go-live and a shadow period before writing dates back. ### Where would a private AI assistant fit? **Answer:** As a read-only explainer and reviewer across S/4HANA and the planner. It can explain slips and flag suspect routing data, while the planner and a human approve every schedule or master data change. ## Source https://www.sap.com/canada/products/erp/partners/delfoi-oy-delfoi-planner-for-sap-s4hana.html ## Search terms delfoi planner sap s4hana, finite scheduling sap s/4hana, sap aps gantt chart add-on, production scheduling s4hana, delfoi sap integration, drag and drop gantt sap production orders --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
