Lesson 3 of 6
Warehouse product data that steers tasks
9 min
Listen to this lesson
In embedded EWM there is no separate product to create. When you create a material in SAP S/4HANA, the EWM product exists in the background and shares the same data: description, units of measure, weights and volumes. What EWM adds is a warehouse product: data that belongs to one warehouse number and one party entitled to dispose. That data decides where stock goes, where it comes from and how it is counted.
Where to maintain it
Warehouse product data is maintained in the Manage Product Master app, which in embedded EWM lets you maintain warehouse and non-warehouse data together, or in the classic Maintain Warehouse Product transaction (/SCWM/MAT1). The warehouse management monitor supports mass changes, and slotting can propose and set many fields through condition records. A warehouse product is not strictly needed for a product to be handled, but most putaway, removal and replenishment logic depends on it, so treat a missing one as a defect.
The indicators that matter most
| Field | What it steers | Contoso value for CMC-ALT-100 |
|---|---|---|
| Putaway control indicator | Selects the storage type search sequence for putaway | PALL → search 0010 high-rack, then 0030 bulk floor |
| Stock removal control indicator | Selects the storage type search sequence for picking | FPCK → pick from 0020 fixed bins, then 0010 |
| Storage section indicator | Chooses sections when section search is active | FAST → aisles 01–02 of 0010 |
| Process type determination indicator | Lets the product get a different warehouse process type | Blank (standard putaway and picking) |
| Cycle counting indicator | Sets how often the product is counted in cycle counting | A (counted most often) |
| Min/max quantity (storage type 0020) | Triggers replenishment of the fixed bin | Min 12, max 48, minimum replenishment 24 |
Warehouse product fields and Contoso's values. Indicator keys are project-defined.
The putaway control indicator is the field testers meet most. During putaway, EWM determines a storage type search sequence from the warehouse number, the putaway control indicator and other inputs such as the warehouse process type, stock type, quantity classification and hazard ratings. It then searches the storage types in that sequence for a bin. If the indicator is empty or wrong, putaway lands in the wrong area or fails with no bin found.
- Does the warehouse product exist for warehouse number 1710 and plant 1710's business partner?No → create it before testing any process · Yes → next
- Is the putaway control indicator set?No → putaway uses a fallback sequence or fails · Yes → next
- Does the indicator point to the intended search sequence?No → fix the indicator or the sequence · Yes → next
- Do the storage types in that sequence have free bins of the right bin type?No → tasks fail or overflow to the next type · Yes → putaway proposal should be correct
Units, weights and why they break warehouses
EWM calculates capacity, handling unit fill and travel effort from the material's units of measure, weights and volumes. A regulator kit maintained at 0.005 kg instead of 0.5 kg lets the system plan 12,000 onto one pallet, and a pallet maintained in the wrong unit makes capacity checks pass for bins that are physically full. These fields are not new, but EWM makes their errors visible on the warehouse floor. Contoso's data migration team checks them for every product that moves into warehouse 1710, not only for new products.
What would you do?
A test of inbound putaway for the fastener kit CMC-FST-010 fails with "no storage bin found." Regulator kits and alternators put away fine. What should the tester check first?
- In embedded EWM the product is the material; the warehouse product adds per-warehouse data.
- Putaway and stock removal control indicators select the storage type search sequences.
- Min/max quantities at storage-type level drive replenishment of fixed bins.
- Wrong weights, volumes and units show up as wrong capacity and packing in EWM.
