EWM & QM integration in SAP S/4HANA 1909

For SAP S/4HANA 1909 system with embedded EWM, this blog lists provides an overview of configurations, key functionalities and limitations of EWM & QM integration

Following QM inspection types are supported with S/4HANA EWM

1701              EWM: Goods Receipt Insp. for Pur. Order

1704              EWM: Goods Receipt Insp. from production

1708              EWM: Stock transfer inspection

1709              EWM: Recurring inspection of batches

Now also standard inspection types are supported without inspection rule in SAP S/4HANA 1909 system with embedded EWM

01                 Goods receipt insp. for purchase order

04                 Goods receipt inspection from production

08                 Stock transfer inspection

09                 Recurring inspection of batches

Basic Configuration & Master Data

Beside basic QM configuration, EWM inspection object should be activated. QM inspection document creation rule can be based on material master data or EWM inspection rule.

In case material master is set as origin of inspection lot, still there is a requirement to create a generic inspection rule (usually based on document type) in /SCWM/QRSETUP to trigger inspection lot creation.

/scwm/qrsetup

Material master data for quality inspection : MM02

During inspection lot creation EWM also decides stock type based on /scwm/qrsetup “Indep. ST Arg” configuration. Even if purchase order and inbound delivery are created with unrestricted use stock type EWM would update stock type to quality based on inspection rule.

There are inspection follow-up actions available provided by SAP

New inspection follow-up actions can be created by copying standard ones

EWM follow-up actions (posting change, put-away warehouse task) are assigned to QM follow up actions.

In case of no inspection rule (EWM embedded in SAP S/4HANA 1909), inspection lot setup is set to no inspection rule.

Process oriented storage control step and quality stock status is set.

Code groups for usage decision needs to be updated for EWM usage decisions. Either new EWM codes are added to an existing code group or new code group is created with EWM codes.

Codes groups can be maintained per plant number, codes groups for plants managed by EWM and Non EWM can be differentiated using following configuration.

Special Cases & Limitations

Inspection lots with “SKIP” status: When an inspection lot is created with “SKIP” status EWM would not update stock type but only delete inspection lot reference on stock. Therefore, if inbound delivery is created with quality stock type it would not be updated in EWM.  In this case it would be better to allow EWM to decide final stock type based on inspection rule (/SCWM/QRSETUP).

Differentiating Purchaser Orders and Stock Transfer Orders for Inspection Lot Creation:  Inspection lot setup can be differentiated for each inbound delivery type, in case delivery types cannot be for different inbound scenarios (like STO and PO case).  Business partner field in inspection rule (SCWM/QRSETUP) can be used to differentiate different business cases (STO &PO) . For STO documents usually each sender plat/storage location would be defined as one business partner, a specific inspection rule can be set in (/SCWM/QRSETUP for partner that represent plant).

Moving Inspection stock from EWM managed storage location to IM-MM managed storage location: Inspection lot related stock in EWM warehouse cannot be transferred to IM-MM managed (non-EWM) managed storage locations in 1909 S/4HANA or previous releases.

Customer returns with quality inspection: Inspection of customer returns are only supported with Advance Return Management (ARM).  When ARM is used with quality inspection document, QA32 EWM inspection or /SCWM/QINSP_S4 cannot be used for result entry. Partial inspection result entry based on handling unit is only possible with material inspection in warehouse tcode : MSR_INSPWH.  Posting changes are replicated to EWM via delivery document. Please refer to OSS note 2806070 – SAP S/4HANA 1909: Release information and restrictions for EWM in SAP S/4HANAHelp Document : Integration with Warehouse Management

Partial result entry per HU: Quality inspection result entry from EWM is possible with quality inspection work center. Quality specific packaging work center in EWM can be used to repack handling units and enter partial inspection result for handling units:   transection code /SCWM/QINSP_S4 – Quality Workload Overview. Partial decision functionality is available with S/4HANA 1709 SP01.

After QM inspection lot result entry follow-up actions can be triggered to create put away warehouse task.

Internal inspection lot creation from EWM: an inspection lot can be created for an available stock directly in EWM, for this purpose IOT5 should be activated and inspection type 1708 should be used. An inspection rule should be created in /scwm/qrsetup an generic inspection rule with owner can be used. Also, an exception code should be defined to record the requirement with following business contexts. Inspection lot creation using RF devices is also supported.

Acceptance Sampling with inspection rule:  Inspection lot can be created before goods receipt posting with inbound delivery creation. Following configurations are required:

In case inspection rules are in use, then a specific inspection rule has to be maintained for acceptance sampling

In case inspection rules are not in use; a quality inspection info record is needed to trigger acceptance sampling. A new inspection type should be created with source inspection type 01 and maintained in quality inspection info record. Quality inspection material master data is required to be maintained accordingly.

Following follow up action can be configured:

Accept:  Stock status would be updated to unrestricted, after goods receipt a second inspection lot is not created

Reject: Goods receipt is blocked.

Accept with reservations: Second inspection document is created after goods receipt.

With 1909 release, EWM QM integration simplified, bugs are fixed. Future improvements are expected in EWM &QM integration with new releases.
