Replenishment with Summarized JIT Calls

Use

With the summarized JIT call you can transfer releases, which are relevant for delivery, from the production system to a vendor. The delivery to a summarized JIT call can take place using exact times and also several times a day. You have the possibility of grouping several material requirements to a JIT call. In addition, a JIT call can contain an unloading point for the materials.

You do not create JIT calls from requirements planning, but from production.

First, you generate schedule lines from requirements planning as a preview, which you transmit as a forecast delivery schedule or a JIT delivery schedule to the vendors and which is not relevant for delivery for the vendors.

As soon as you really need the material in production, generate a summarized JIT call, which is relevant for delivery, by setting a kanban to EMPTY or create a new item in an existing JIT call. You can trigger a summarized JIT call both via classic as well as event-driven KANBAN.

Features

You generate a summarized JIT call in the SAP system by setting a kanban to EMPTY or by creating an event-driven kanban. Please also read the section Generating and Transmitting a summarized JIT call.

A summarized JIT call can contain delivery dates using exact times as well as exact days. Please also read the section Determination of Delivery Date.

You have the possibility of grouping several material requirements/kanbans to a JIT call. In a grouping, the system attaches the individual requirements as items to the JIT call header. You can group kanbans in various ways.

You can group all material requirements/kanbans, whose delivery dates are in a specific period of a shift sequence or a planning calendar.

The grouping can take place both using exact days or times.

You can group requirements via a plant or via a combination of plant and unloading point.

Note

If you group according to delivery date you must simultaneously group according to plant or according to plant and unloading point). You can, however, group according to plant or plant and unloading point, without having to group according to delivery date.

To group kanbans, please read the sectionSummarizing kanbans to one JIT call.

You can transfer the summarized JIT call via various media and in several formats.

You can send summarized JIT calls via EDI as well as via printer (letter), fax or E-mail. The dispatch is controlled via message management. Message management checks whether a message can be found for the criteria entered and triggers a message default. Please also read the sections Creating a Summarized JIT Call,Transmitting a Summarized JIT call and Message management structure.

You can carry out the goods receipt both via KANBAN and the summarized JIT call as well as by your scheduling agreement item. See also Goods Receipt with the Summarized JIT Call.

Subcontracting: For replenishment via summarized JIT calls, you can use subcontracting. Here, it is important that schedule lines are created in the MRP run and these have not been created manually. The MRP run then also creates the requirements of materials provided which you provide to your supplier.
