Work orders are planned in SAP — but what happened to them on the floor was logged on paper and in spreadsheets. The company needed to bring production into digital form right at the machines, without touching the SAP environment the rest of the business runs on. Weighed quantities, breaks, faults and confirmations were to be recorded where they happen and flow back to SAP without manual re-entry. ## Production floor requirements – tablets, SAP and five production phases An operator's hands are full of raw materials, not on a keyboard — and every order passes through several halls and people. - **A tablet, not a desktop**: Large touch targets, password-free login with a worker ID and PIN, and a dark theme for a dimmer production hall. - **SAP in both directions**: Orders are loaded from SAP in batches. Confirmed data has to make it back reliably, with status tracking for every write and retries on failure. - **Five phases, several work centres**: Weighing, milling, tinting, quality control and discharge. Several people can work a phase at once, and work can be paused and finished later. - **Simplification during development**: We merged the originally separate server component into the rest of the system during development, without pausing delivery of new features. ## Principle Every value is recorded at the scale or machine the moment it originates, and reaches SAP without re-typing. - **SAP as the master source**: Orders and recipes come from SAP. Chemolak Mix adds what actually happened on the floor and sends it back. - **Deviation at the point of entry**: The operator sees the recipe target and enters the actual. The system calculates the deviation immediately, with no spreadsheet work at the end of the shift. - **One system for the floor and the office**: The operator app and the admin console work on the same data. ## A work order's path – from SAP import to writeback Every work order takes the same path, and every step leaves a record. 1. **SAP import** – Orders and recipe components in batches. 2. **Plan and priority** – The planner assigns a work centre and sets the order. 3. **Work centre** – The operator finds it in the queue on their tablet. 4. **Weighing** – Target vs. actual for every raw material. 5. **Next phases** – Milling, tinting, quality control, discharge. 6. **Writeback** – Quantities, consumption and faults back to SAP. ## Order planning – priorities, halls and work centres Planners see work orders with their phase, work centre, operator and progress. They filter by hall, phase or status and reorder orders by dragging rows. Orders at risk of missing their deadline are flagged in the operators' queue. - Order sequence set by moving rows - Management of halls, work centres and machines - Users with a role, PIN and assigned work centres ## Operator terminal – the order queue for one work centre Operators log in with a worker ID and PIN and see the order queue for their work centre — with priority, shade, quantity and planned start. One tap picks up where they left off. The order detail shows all five phases, the active one and the list of raw materials with their target quantities. A colleague can be added to the job. ## Weighing raw materials – target, actual and deviation Weighing is a live checklist of the recipe's raw materials. For each one the operator sees the target, enters the actual weight on a large numeric keypad, and the deviation appears immediately. The phase can't be closed until every component is confirmed. - Planned vs. actual for every raw material - A large keypad for finger operation - Phase time and weighing progress in one place ## Phase completion and fault reporting – directly from the tablet After weighing, the operator confirms a summary and the order moves on to the next work centre. When work is interrupted — a fault, a break, the end of a shift — the order is paused and can be finished later. Machine faults are reported straight from the tablet with a type and description. The shift lead sees them in the console at once, and they're part of the writeback to SAP. ## Two-way SAP integration – order import and writeback Orders arrive from SAP in batches. Each batch shows how many records loaded and which ones need to be resolved by hand. In the other direction, confirmed quantities, consumed materials and reported faults are sent to SAP. The status of every write is tracked, and failed writes are retried. - Batch order import with record checks - Writeback with retries on failure - A record of every synchronisation ## Order detail – history across work centres For every order, the admin sees phase progress, assigned operators, recipe components with target, actual and batch, and a timeline of operations — who started, paused and finished what. ## Reports for shift leads – performance, delays and idle machines Because every phase is recorded in real time, the console can show what's running, what's late and which machines are down. Reports compare operator and work-center performance and planned phase times against actual ones. ## Digital production records – with two-way SAP integration Chemolak Mix replaced paper and spreadsheet logs right on the production floor. Shift leads and planners have real-time visibility, and confirmed data flows back to SAP without manual re-entry. ### What we delivered - Operator app for tablets - Admin console for planners and shift leads - Two-way SAP integration - Records for five production phases - Operator and work-centre performance reports --- Web version: https://interfase.sk/en/case-studies/chemolak/mix llms.txt: https://interfase.sk/llms.txt
