Stock types, batches & serial numbers

EWM stock is held in quants: product + quantity in a bin or HU, distinguished by attributes such as stock type, batch, owner, party entitled to dispose, stock usage (sales order, project) and goods-receipt date.

• Quants with identical attributes in the same location are merged.
• GR date and SLED drive FIFO/FEFO removal strategies.
• The stock overview in the warehouse monitor shows quants by bin, HU and attributes.

EWM stock types distinguish not only unrestricted/quality/blocked but also whether stock is in putaway or in the warehouse — for example F1 unrestricted in putaway and F2 unrestricted in warehouse; Q3/Q4 quality inspection; B5/B6 blocked. Availability groups map EWM stock to the S/4HANA storage location.

• GR posts into the 'putaway' stock type; completing putaway changes it to the 'in warehouse' type.
• Availability group + plant = storage location in IM (e.g. ROD receiving-on-dock vs AFS available-for-sale).
• Posting changes between stock types can be done in EWM and update IM automatically.

Batches and their classification are shared with S/4HANA (embedded) or replicated (decentralised). EWM can require the batch at GR, determine batches in outbound based on ERP batch selection criteria, and split HUs by batch.

• Batch-managed products need batch-relevant settings in both systems.
• SLED and production date drive FEFO stock removal rules.
• Batch changes and splits can be done in EWM with posting changes.

Serial-number requirements are set by the warehouse-number-dependent serial number profile: serials at document level (captured on the delivery), at warehouse-number level (captured at GR/GI) or inventory-relevant (tracked per bin for every movement).

• Inventory-relevant serials give the strongest traceability and the most RF scanning.
• Serial numbers can be pre-advised via ASN/DESADV.
• Align with the S/4HANA serial number profile to avoid GI errors.

EWM supports multiple owners (e.g. 3PL scenarios) and special stocks such as sales-order stock, project stock, supplier consignment and customer returns, visible as quant attributes.

• Owner differs from party entitled to dispose in 3PL and consignment.
• Special stocks must be considered in stock removal and replenishment.
• Stock comparison with IM uses /SCWM/ERP_STOCKCHECK.
