The next generation of just-in-time processing in SAP S/4HANA enables smaller quantities of parts to be delivered directly to the production supply area of the line at the right time several times a day. This includes, among other things, the processing of quantity (JIT) and sequence (JIS) calls from both the outbound and inbound perspectives.
JIT Supply to Production (S2P) covers the entire process from release to the supplier, warehouse or external service provider to the receipt of components and assemblies on the production line. The JIT call-off is sent from the production supply area to the warehouse or external supplier to request replenishment of materials. The production synchronous call-off can be sent for a vehicle schedule order.
JIT Supply to Customer (S2C) covers the entire process from receipt of the JIT or JIS call-offs to delivery and invoicing of the components or assemblies to the respective customer.
JIT supply begins with the receipt of the JIT call-off from the customer. These call-offs are directly relevant for shipping, provided there is sufficient stock available from in-house production or external procurement. The shipping process begins with delivery creation and ends with goods issue posting.
