Just-In-Time Supply to Customer

The process starts with receiving Just-In-Time (JIT) calls from customers. 

JIT calls are sent via an Electronic Data Interchange (EDI) integration and contain the component details with the requirements date and time. The Material Planner (JIT Supply) monitors and manages the JIT calls from customers.

The production planner releases production-relevant component group materials for summarized JIT calls or production-relevant package units for sequenced JIT calls for production.

The production operator then confirms the production of the component groups.

The Shipping Specialist (JIT Supply) creates deliveries on open JIT calls, with status reflected accordingly. Advanced shipping notifications are sent via EDI to the OEM. The shipping specialist can also create handling units for summarized JIT calls.

After picking and posting of goods issue, the JIT call status is updated accordingly. Optionally, for summarized JIT calls picking and post goods issue can also be done in EWM. 

After the billing is created, the JIT call is updated to completed status.
