Next Generation JIT (Just in Time) for Production

 What is JIT – Just In Time?

The space is always limited on a production line or near production lines. Therefore, manufacturers do not want to stock products close to lines but rather prefer to order and schedule the delivery when products are needed to complete production, several times during a day.

Types of Just in Time:

• Just-In-Time (JIT)
  • The sequence of parts does not matter e.g., if production request components A, B, C & D, all of them can be picked and delivered to the line at the same time.
• Just-In-Sequence (JIS)
  • The sequence of the parts do matter in just-in-sequence (JIS), the right components need to be delivered to the line in the right sequence.

Next-Generation JIT: Just-In-Time and Just-In-Sequence in SAP S/4HANA

SAP Release: The integration between JIT and EWM solution is available as of release S/4HANA 2020 FPS1 Deployment option: EWM embedded in S4 HANA

Processes Covered:

1.JIT Supply to Production

Covers the complete process from the release to the supplier, warehouse or external service agent up to the receipt of components and assemblies at the production line.

2.JIT Supply to Customer

Covers the end-to-end process from receiving the JIT or JIS calls, up to delivering and billing the components or modules to the respective customer.

In today’s blog, I will cover the JIT Supply to Production from the EWM managed warehouse

The diagram below shows the integration between S4 REP and EWM, process flow with data points:

Fiori Based Only - Apps Available for Next Generation JIT in SAP S/4 HANA

Fiori Roles Required:

• Production Operator – Lean Manufacturing
• Production Planner – Lean Manufacturing
• Production Supervisor – Lean Manufacturing

Configuration required

1. Fiori activate services as below (transaction /n/iwfnd/maint_service):
   1. API_NJIT_CCYC_MANAGE_SRV
   2. JITCONTROLCYCLES_SRV
   3. LE_JIT_JITCALL_MANAGE_SRV
   4. APS_CHANGE_DOCUMENTS_SRV
2. Custom role added to user: ZMSCG_JITCYCLES_MANAGE
3. User roles needed:
   1. SAP_BR_PRODN_OPTR_LEAN_MFG
   2. SAP_BR_PRODN_PLNR_LEAN_MFG
   3. SAP_BR_PRODN_SUPVR_LEAN_MFG
4. BC Set activation: /SCWM/DLV_STOCK_TRANSFER_JIT
5. S4 ERP Configuration

6. EWM Configuration

Master Data & Process Steps

1. Create PSA
2. Create PSA bin

3. Assign PSA stage bin

4. Create and release the control cycle

5. Request Replenishments for Control Cycles

                    SEND the JIT call. The JIT call will be created in S4 ERP, transferred to EWM

6. JIT call in EWM

7. From here onwards, we can create and assign the JIT warehouse request to a wave (optional), release wave (optional), create warehouse task and warehosue order then continue picking and staging as we do normally.

Thanks for reading my first blog. Stay tuned for more!!!
